Weyl phonons in chiral crystals
Tiantian Zhang, Zhiheng Huang, Zitian Pan +3
Chirality is an indispensable concept that pervades fundamental science and nature, manifesting itself in diverse forms such as chiral quasiparticles and chiral structures. Of part…
Conversion of chiral phonons into magnons in ferromagnets and antiferromagnets
Dapeng Yao, Shuichi Murakami
Chiral phonons with atomic rotations converted into electron spins result in a change of spin magnetizations in crystals. In this paper, we investigate a new conversion of chiral p…
Polarization Jumps across Topological Phase Transitions in Two-dimensional Systems
Hiroki Yoshida, Tiantian Zhang, Shuichi Murakami
In topological phase transitions involving a change in topological invariants such as the Chern number and the topological invariant, the gap closes, and the electri…
Effects of first- and second-order topological phases on equilibrium crystal shapes
Yutaro Tanaka, Shuichi Murakami
We study equilibrium crystal shapes of a topological insulator (TI), a topological crystalline insulator (TCI) protected by mirror symmetry, and a second-order topological insulato…
Optical non-Hermitian skin effect in two-dimensional uniform media
Taiki Yoda, Yuto Moritake, Kenta Takata +3
The non-Hermitian skin effect (NHSE) is a novel localization phenomenon in certain non-Hermitian systems with gain and/or loss. Most of previous works study the non-Hermitian skin…
Morse theory study on the evolution of nodal lines in -symmetric nodal-line semimetals
Manabu Takeichi, Ryo Furuta, Shuichi Murakami
A nodal-line semimetal is a topological gapless phase containing one-dimensional degeneracies called nodal lines. The nodal lines are deformed by a continuous change of the system…
