A3 Naoki KAWASHIMA The Institute for Solid State Physics kawashima AT We are developing new computational methods and algorithms for analytically intractable problems in condensed matter theory. We also use them in large-scale computing on parallel computers. Specifically, we study quantum spin liquids by tensor-network method, Z2 vortex dissociation transition by cluster algorithm, spinon deconfinement critical phenomena by quantum Monte Carlo, optical lattice systems by worm algorithm, and spin glass critical phenomena.
A3 Mio MURAO Department of Physics We consider that a quantum computer is not just a machine to run computational algorithms but also a machine to perform any operations allowed by quantum mechanics. We analyze what kinds of new properties and effects may appear in quantum systems by using quantum computers to improve our understanding of quantum mechanics from an operational point of view. We also investigate applications of quantum properties and effects such as entanglement for information processing, communication, precise measurement and manipulations.
A3 Masao OGATA Department of Physics Condensed Matter Theory: Especially theories in many-body problems where quantum phenomena play essential roles. For example, strongly correlated electron systems, high-temperature superconductivity, magnetism, low-dimensional conductors such as organic conductors, mesoscopic systems, oxides with orbital, spin and charge degrees of freedom, and unconventional superconductivity phenomena. We use field-theoretical methods, exact solutions, renormalization group, variational theory, and numerical simulations.

A3 Taisuke OZAKI The Institute for Solid State Physics In accordance with development of recent massively parallel computers, first-principles calculations based on density functional theories (DFT) have been playing a very important role in understanding and designing properties of a wide variety of materials. 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. In addition to this, we are aiming at realization of materials design from first-principles.

A3 Osamu SUGINO The Institute for Solid State Physics Our research, the first principles calculation of materials, is motivated by keen interest in explanation of properties of materials and understanding of phenomena occurring in condensed phases by solving basic equations like Schroedinger equation. We also develop new computational methods to make more and more complex phenomena within the target of first principles calculation. The present theme: stimulated electron-ion dynamics in the condensed phases, tunneling phenomena via nano-structures or ultrathin layers, and catalytic reactions occurring at surface or interfaces.
A3 Synge TODO Department of Physics We are exploring novel methods in computational physics based on stochastic method such as the Monte Carlo simulation, path-integral representation of quantum fluctuations, information compression by using the singular value decomposition and the tensor network, statistical machine learning, etc. By making full use of these powerful numerical methods, we aim to elucidate various exotic phases, phase transitions, and dynamics specific to quantum many-body systems, from strongly correlated systems such as the spin systems and the Bose-Hubbard model to real materials. We are also researching parallelization methods for leading-edge supercomputers, and developing and releasing open-source software for next-generation physics simulations.
A3 Naoto TSUJI Department of Physics tsuji [at] 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 have revealed various possibilities that novel states of matter do emerge out of equilibrium. We are trying to understand their mechanism and explore the frontier of nonequilibrium physics.
