A1 Koichi HAMAGUCHI Department of Physics http://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. I have worked on model building, phenomenological study and particle cosmology of models beyond the Standard Model, such as the 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.
A1 Simeon HELLERMAN Kavli Institute for the Physics and Mathematics of the Universe 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.
A1 Kentaro HORI Kavli Institute for the Physics and Mathematics of the Universe https://db.ipmu.jp/member/personal/143en.html 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.
A1 Masahiro IBE 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.
A1 Shigeki MATSUMOTO Kavli Institute for the Physics and Mathematics of the Universe 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.
A1 *# Yutaka MATSUO Department of Physics http://www-hep.phys.s.u-tokyo.ac.jp matsuo[at]phys.s.u-tokyo.ac.jp Subjects: Quantum Gravity, Superstring theory, Quantum field theory and related mathematica physics. More concretely, (1) Formulation of Branes in M-theory (2) related new symmetry and geometry (3) infinite dimensional symmetry appearing in 4D Yang-Mills and 2D solvable models
A1 MELIA Thomas Kavli Institute for the Physics and Mathematics of the Universe https://db.ipmu.jp/member/personal/2727en.html tom.melia[at]ipmu.jp 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.

A1 Yuji TACHIKAWA Kavli Institute for the Physics and Mathematics of the Universe http://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.
A1 *# Izumi TSUTSUI High Energy Accelerator Research Organization http://research.kek.jp/people/itsutsui/index_e.html izumi.tsutsui[at]kek.jp Our group investigates the foundations of quantum mechanics and the nonperturbative aspects of quantum field theory. Recent research topics are: 1) Foundations of Quantum Mechanics * Quantum measurement (Weak Value and Weak Measurement) * Entanglement and quantum correlations in particle physics 2) Gauge Field Theory and Topology * Quantization of systems on topologically nontrivial spaces * Physics of nonperturbative field configurations such as topological solitons
A1 Taizan WATARI Kavli Institute for the Physics and Mathematics of the Universe http://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. Visit this page https://www.ipmu.jp/en/research-activities/PhD-programs.html for more information. My research interests in recent years include string duality, mathematics seen in the language of string theory, and physics applications of string theory (to hadron scattering, grand unification and early universe). To see whether I am ready to host one more PhD student next year, visit my web page http://member.ipmu.jp/taizan.watari/messageNfaq.html
