Toward simulating Superstring/M-theory on a Quantum Computer
2020年10月23日17:00 - 18:00
花田 政範 (Department of Mathematics, University of Surrey, UK)
We present a framework for simulating superstring/M-theory on a quantum computer, based on holographic duality. Because holographicduality maps superstring/M-theory to quantum field theories (QFTs), w...続きを読む

Realistic shell model and chiral three-body force
2020年10月22日13:30 - 15:00
福井 徳朗 (京都大学 基礎物理学研究所 研究員)
We show an evolution to derive the effective Hamiltonian in the shell-model framework starting from two- and three-body interactions based on the chiral effective field theory. A new way to calculate ...続きを読む

Lefschetz-thimble inspired analysis of the Dykhne–Davis–Pechukas method and an application for the Schwinger Mechanism
2020年8月21日13:00 - 14:30
島崎 拓哉 (東京大学 ハドロン理論グループ 研究生)
Dykhne–Davis–Pechukas (DDP) method is a common approximation scheme for the transition probability in two-level quantum systems, as realized in the Landau–Zener effect, leading to an exponentially dam...続きを読む

Nambu-Goldstone fermion in a Bose-Fermi mixture with an explicitly broken supersymmetry
2020年8月7日13:00 - 14:30
田島 裕之 (高知大学 自然科学系理工学部門 特任助教)
Supersymmetry, which is a symmetry associated with interchange between bosons and fermions, is one of the most important symmetries in high-energy physics but its evidence has never been observed yet....続きを読む

Complex Langevin study of an attractively interacting two-component Fermi gas in 1D with population imbalance
2020年7月10日13:30 - 14:30
筒井 翔一朗 (理研 量子ハドロン物理学研究室 博士研究員)
We investigate an attractively interacting two-component Fermi gas in 1D described by the Gaudin-Yang model with population imbalance. While the Gaudin-Yang model is known as a solvable model based on...続きを読む

Field theoretical approach to relativistic hydrodynamics
2020年6月12日13:00 - 14:30
本郷 優 (数理創造プログラム 客員研究員（学術機関）)
Hydrodynamics is a low-energy effective theory of a conserved charge density, which describes a long-distance and long-time behavior of many-body systems. It is applicable not only to a non-relativist...続きを読む
