A4 *＃ Shuji HASEGAWA Department of Physics http://www-surface.phys.s.u-tokyo.ac.jp/top.html shuji[at]phys.s.u-tokyo.ac.jp Our research targets are atomic arrangements, electronic band structures, electronic/spin transport, optical responses, phase transitions and other functional properties of a few atomic layers, atomic wires, atomic clusters, and other nanometer-scale structures formed on crystal surfaces such as semiconductors, metals, and topological insulators, etc. We utilize various kinds of experimental techniques such as electron diffraction/microscopy, scanning tunneling microscopy/spectroscopy, photoemission spectroscopy, microscopic four-point probe methods, molecular beam epitaxy, and focused ion beam techniques. We recently found single-atom-layer superconductors, and suppression of backscattering of carriers at topological surfaces, etc.
A4   Masayuki HASHISAKA The Institute for Solid State Physics https://hashisaka.issp.u-tokyo.ac.jp/Eindex.html hashisaka[at]issp.u-tokyo.ac.jp The interplay of quantum nature and electron correlation causes exotic phenomena in condensed matter, such as superconductivity and the fractional quantum Hall effect. 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 paradigmatic is the quasiparticle in the fractional quantum Hall state, which has fractional charge and anyonic statistics that differ from the Bose and Fermi statistics. Our goal is to establish novel quantum technologies based on the intriguing nature of such exotic quasiparticles.

A4   Kensuke KOBAYASHI Institute for Physics of Intelligence https://meso.phys.s.u-tokyo.ac.jp/en/ kensuke[at]phys.s.u-tokyo.ac.jp Recent progress in nanotechnology enables us to directly address quantum behavior of electrons in nano-devices made of metal or semiconductor. The advantage of this research field, which is called "mesoscopic physics" or "nanophysics", lies in the various controllability and the versatile degrees of freedom in the device design. We explore this field to understand, predict, and control various novel quantum, many-body, and nonequilibrium effects in nano-devices in terms of the dynamical aspects of electron behavior.
A4   Takeshi KONDO The Institute for Solid State Physics http://kondo1215.issp.u-tokyo.ac.jp kondo1215[at]issp.u-tokyo.ac.jp The angle-resolved photoemission spectroscopy (ARPES) is a powerful technique to visualize the band structure. With the spin-resolved technique, we can identify the spin-polarized character of the band. In addition, the time-resolved ARPES realized with a pump-probe technique can track the reordering process of electron system from its nonequilibrium state. In our laboratory, we utilize these various ARPES techniques and explore novel electronic states of matter. Furthermore, we develop a new ARPES machine capable of achieving both the lowest measurement temperature and the highest energy resolution in the world by innovating a 3He cryostat and a laser source.

With the new probes, we investigate spin-polarized electronic states and dynamics in monatomic layers that have intriguing Dirac Fermions. We aim to make the comprehensive educations to students and we also promote concerting researches with various quantum beams, such as positrons and electrons.

A4   Tohru OKAMOTO Department of Physics http://dolphin.phys.s.u-tokyo.ac.jp/index-e.html okamoto[at]phys.s.u-tokyo.ac.jp We study low temperature electronic properties of low-dimensional systems, including the quantum Hall effect on semiconductor surfaces and the superconductivity of monolayer films.
A4   Akito SAKAI Department of Physics https://www.nakatsuji-lab.phys.s.u-tokyo.ac.jp/ akito[at]phys.s.u-tokyo.ac.jp Strong correlation between electrons can induce non-trivial electronic states. One of the famous examples is Tomonaga-Luttinger liquid in the interacting one-dimensional electron system. Similarly, such a “strange metal”, where the quasiparticle picture does not hold, can also appear in the three-dimensional system. We find out the ideal system which can be described by a simple Hamiltonian at low temperature, and perform various experiments such as specific heat, magnetization, electric and thermal transport, and magnetostriction. Our goal is to reveal novel quantum states induced by the entanglement.
