| Nuclear Theory (A0) | FUKUSHIMA Kenji | Department of Physics | | fuku[at]nt.phys.s.u-tokyo.ac.jp | We investigate various phenomena originating from the "strong interaction" that is associated with one of the most fundamental forces in nature. Quarks and gluons interact strongly to form hadrons such as pions, nucleons, and so on, and hadrons are constituents of any materials we know. From the same theory of the strong interaction, unexpectedly amusing physics can appear in special environments like high temperature, high density, or strong background (electromagnetic or gravitational) fields. We are pursuing novel phenomena based on this established and yet profound theory of the strong interaction. |
| Nuclear Theory (A0) | LIANG Haozhao | Department of Physics | https://tnp.phys.s.u-tokyo.ac.jp/en/ | haozhao.liang[at]phys.s.u-tokyo.ac.jp | Our research mainly focuses on the nuclear many-body theories and the relevant interdisciplinary studies in nuclear physics, nuclear astrophysics, and particle physics.
Key topics include: nuclear density functional theory (DFT), structure of exotic nuclei, hidden symmetries in atomic nuclei, nuclear collective excitations, nuclear weak-interaction processes and r-process nucleosynthesis, etc. |
| Theoretical Particle Physics (A1) | HAMAGUCHI Koichi | Department of Physics | https://www-hep.phys.s.u-tokyo.ac.jp/~hama/welcome-e.html | hama[at]hep-th.phys.s.u-tokyo.ac.jp | I am interested in physics beyond the energy scale of the Standard Model of particle physics, and doing research aiming at a more fundamental unified theory underlying in nature. Currently I am working on phenomenology and particle cosmology which are mainly based on supersymmetric models. I also plan to pay attention to the latest results from high energy experiments and astrophysical observations, and then feed them back to theoretical research. |
| Theoretical Particle Physics (A1) | HELLERMAN Simeon | IPMU | https://db.ipmu.jp/member/personal/154en.html | | I study the dynamics of gravity in situations where the short-distance structure of space-time becomes important, for example, in the early Universe. As a tool, I use string theory, which is the unique dynamical system incorporating both the existence of gravity and the uncertainty principle of quantum mechanics.
My recent work has mapped out the various different phases of string theory and the transitions the theory can make from one phase to another, in a cosmological environment. These phase transitions alter several features of the theory dramatically. For instance, the number of dimensions of the space-time can change, or the transition may restore a highly stable type of order known as supersymmetry, or else the character of the string dynamics may change altogether. |
| Theoretical Particle Physics (A1) | HORI Kentaro | IPMU | https://member.ipmu.jp/kentaro.hori/ | kentaro.hori[at]ipmu.jp | My research is centered on discovery, understanding and application of duality in quantum field theory such as electric-magnetic duality and mirror symmetry; structure and properties of branes and orientifolds in superstring theory. It is sometimes developed through interaction with mathematics. |
| Theoretical Particle Physics (A1) | IBE Masahiro | Institute for Cosmic Ray Research | https://th.icrr.u-tokyo.ac.jp/ | ibe[at]icrr.u-tokyo.ac.jp | In my research, I have focused on physics beyond the Standard Model which completes the Higgs mechanism at the energy scale around the TeV. The evidences of the new physics are expected to be discovered at the coming generation of collider experiments such as the large hadron collider (LHC) experiments. Especially, I have put emphasis on the interplay between the phenomenological aspects of the new physics and its cosmological/astrophysical implications. By the rapid progress in the cosmological/astrophysical observations as well as the full operation of the LHC experiments, the studies which exploit both particle phenomenology and cosmology/astrophysics will be more important than ever. |
| Theoretical Particle Physics (A1) | MATSUMOTO Shigeki | IPMU | https://db.ipmu.jp/member/personal/227en.html | shigeki.matsumoto[at]ipmu.jp | I am so far studying dark matter (DM) in particle physics; proposing interesting DM candidates, finding new mechanisms on DM processes, suggesting experimental methods to test the candidates, and contributing to DM search projects by showing the range of DM mass and interactions, through various international and interdisciplinary collaborations with high-energy experimentalists, cosmologists, astronomers, and even chemists. |
| Theoretical Particle Physics (A1) | MELIA Thomas | IPMU | https://db.ipmu.jp/member/personal/2727en.html | | I am currently interested in exploring particle phenomenology in two main areas. The first is in devising novel analyses at the LHC or future colliders to search for beyond the (or interesting ‘within the’) standard model physics. The second is the effort to directly detect dark matter, where in particular I have been thinking about designing new small-scale experiments with low energy thresholds. I am also interested in uncovering – and putting to use – new mathematical structures in quantum field theory. Conformal representation theory, commutative algebra, and cohomology have proven important in organizing the way we think about realworld effective QFTs. Standard model scattering amplitudes harbour hidden symmetries. I am interested in developing these ideas further. |

| Theoretical Particle Physics (A1) | TACHIKAWA Yuji | IPMU | https://member.ipmu.jp/yuji.tachikawa/ | yuji.tachikawa[at]ipmu.jp | I mainly study quantum field theory (QFT), which governs the physics of elementary particles. QFT is especially interesting in the strongly-coupled regime, and is analyzable with just pencil, paper and a bit of computing power if we further assume the supersymmetry, a symmetry exchanging fermions and bosons. Supersymmetric quantum field theory is best studied by embedding it in string theory, which is another main subject of my study. An interesting aspect of this line of research is that many modern mathematical concepts somehow appear naturally. |
| Theoretical Particle Physics (A1) | WATARI Taizan | IPMU | https://member.ipmu.jp/taizan.watari/index.html | taizan.watari[at]ipmu.jp | Institute for the Physics and Mathematics of the Universe (IPMU) welcomes graduate students who major in theoretical particle physics from the A1 subcourse (A5 subcourse for cosmology major). My research interest covers broad area in theoretical particle physics and dynamics of gauge theories. Theory of the very early universe is also a part of it, because quantum field theories and quantum gravity are the appropriate theoretical frame works to talk about the very early stage of the universe. I have been also trying to exploit superstring theory for a better understanding of particle physics, gauge theories and early universe.

We have been developing efficient and accurate methods and software packages to extend applicability of DFT to more realistic systems as discussed in industry. Although the computational cost of the conventional DFT method scales as the third power of number of atoms, we have developed an O(N) Krylov subspace method, of which computational cost scales only linearly, based on nearsightedness of electron.

| Theoretical Condensed Matter Physics (A3) | TSUJI Naoto | Department of Physics | http://dyn.phys.s.u-tokyo.ac.jp/home/index.php/welcome/ | tsuji[at]phys.s.u-tokyo.ac.jp | We are interested in nonequilibrium physics of quantum many-body systems and statistical mechanics. The aim is to realize a new order or new physical property by driving quantum systems out of equilibrium. At first sight, it sounds unlikely to happen because energy injected by an external drive would turn into heat, which would destroy all the interesting properties of quantum many-body systems that might emerge at low energies. However, contrary to our intuition, recent studies found various possibilities such that novel states of matter that can never be realized in equilibrium do emerge out of equilibrium. We are trying to understand their mechanism and explore the frontier of nonequilibrium physics. |

Our research aims to investigate these phenomena using nanofabrication and our original measurement techniques. The quantum many-body systems sometimes show their peculiarity as the beautiful characteristics of elementary excitations.

The universe appears to be a vast, cold, quiet expanse of space, but is it true? The answer is NO: Recent studies in X-rays and gamma-rays show us that there are full of hot and energetic phenomena, such as explosion of stars, matter getting sucked into black holes, vast gas around clusters of galaxies. We investigate such energetic celestial objects with X-rays and gamma-ray telescopes in the space and ground, and study the mechanical and chemical evolution of the universe. We utilize the X-ray space satellite Hitomi, ground-based very high energy gamma-ray observatory CTA, as well as the recent X-ray and gamma-ray missions such as Suzaku, Chandra, XMM-Newton, and Chandra. We also develop next generation high-energy astrophysics mission, such as Athena. |

How has it evolved? These are the key questions of our research. We explore these fundamental questions primarily through observing cosmic microwave background (CMB), the light from the very beginning of the universe. Through CMB, we study not only the fundamental nature of the universe, but also particle physics as well, such as the nature of neutrinos and unknown particles. Our approach is that of experimental physics, and our research entails development of cutting edge technologies such as those using superconducting instrumentation, and low-temperature and microwave engineering. |

The theory of cosmic inflation can be tested by measuring the B-mode pattern in the CMB polarization experimentally. We are active member of LiteBIRD, the post ESA Planck satellite, to measure the CMB B-mode polarization.

| Astrophysics and Astronomy (A8) | MORIYAMA Shigetaka | Institute for Cosmic Ray Research | https://www-sk.icrr.u-tokyo.ac.jp/ | moriyama[at]icrr.u-tokyo.ac.jp | My fields of interest include dark matter, axions, neutrino physics, and proton decay. My research comprises of two experimental approaches. The first approach involves the use of a liquid xenon target that is sensitive to an energy scale ranging from sub-keV to MeV. The XENONnT detector with ~10 ton of liquid xenon is used to discover dark matter particle in the Universe with the world best sensitivity. The second approach involves the use of Super-Kamiokande. The hierarchy of neutrino masses and CP violation in the lepton sector may be crucial for understanding the existence of matter in the Universe, and an observation of proton decay clearly indicates a large framework of particle physics. We are working to realize a much larger detector, the Hyper-Kamiokande. |

| Astrophysics and Astronomy (A8) | SAKO Takashi | Institute for Cosmic Ray Research | https://www.icrr.u-tokyo.ac.jp/~sako/index.html | sako[at]icrr.u-tokyo.ac.jp | Cosmic-rays are high-energy particles accelerated somewhere in the universe. Search of their origin and study of high-energy physics using CRs are called astroparticle physics. My research is to observe particles not deflected or less deflected by cosmic magnetic field to pinpoint their origins. One technique is observation of gamma rays. In our galaxy, CRs are accelerated up to PeV and they emit 100TeV-PeV gamma rays. To observe these gamma rays, new experiment ALPACA is under construction in Bolivia. Another way is to concentrate on the highest energy CRs such as 10^20eV. To compensate low flux, observation with >1000km^2 called Telescope Array is on going in USA. |

| Astrophysics and Astronomy (A8) | VAGINS Mark | IPMU | https://db.ipmu.jp/member/personal/27en.html | mark.vagins[at]ipmu.jp | My research is focused on developing new methods of observing neutrinos, both through the enhancement of existing detectors like Super-Kamiokande (Super-K) and via the design and construction of future facilities like Hyper-Kamiokande. One of my main goals is to measure, for the first time, the diffuse supernova neutrino background (DSNB), often called the “relic” supernova neutrinos.
Adding water-soluble gadolinium to Super-K - an idea I co-invented - should allow us to detect these relic neutrinos without having to build an all-new experiment. Enhancing Super-K in this manner will also make possible other new physics, including high-statistics reactor antineutrino oscillation studies, as well as improve studies of neutrino oscillations and proton decay searches. |
