Mirror skin effect and its electric circuit simulation
Tsuneya Yoshida, Tomonari Mizoguchi, Yasuhiro Hatsugai
We analyze impacts of crystalline symmetry on the non-Hermitian skin effects. Focusing on mirror symmetry, we propose a novel type of skin effects, a mirror skin effect, which resu…
Reflection-Symmetry Protected Antiferromagnetic Topological Insulator in Three-Dimensional Heavy-Fermion Systems
Kazuhiro Kimura, Tsuneya Yoshida, Norio Kawakami
We study the topological properties of an antiferromagnetic phase with reflection symmetry in three-dimensional heavy-fermion systems. We here propose a reflection-symmetric topolo…
Higher-order topological phases in a spring-mass model on a breathing kagome lattice
Hiromasa Wakao, Tsuneya Yoshida, Hiromu Araki +2
We propose a realization of higher-order topological phases in a spring-mass model with a breathing kagome structure. To demonstrate the existence of the higher-order topological p…
Non-Hermitian fractional quantum Hall states
Tsuneya Yoshida, Koji Kudo, Yasuhiro Hatsugai
We demonstrate the emergence of a topological ordered phase for non-Hermitian systems. Specifically, we elucidate that systems with non-Hermitian two-body interactions show a fract…
Relation between exceptional points and the Kondo effect in -electron materials
Yoshihiro Michishita, Tsuneya Yoshida, Robert Peters
We study the impact of nonhermiticity due to strong correlations in f-electron materials. One of the most remarkable phenomena occurring in nonhermitian systems is the emergence of…
Chiral-symmetry protected exceptional torus in correlated nodal-line semi-metals
Kazuhiro Kimura, Tsuneya Yoshida, Norio Kawakami
We analyze a diamond-lattice Hubbard model with the spatially modulated Hubbard interaction. Our dynamical mean-field analysis with special emphasis on non-Hermitian properties elu…
