Topological gap labeling with the third Chern numbers in three-dimensional quasicrystals
Kazuki Yamamoto, Mikito Koshino
We study the topological gap labeling of general 3D quasicrystals and we find that every gap in the spectrum is characterized by a set of the third Chern numbers. We show that a qu…

Rectification in Nonequilibrium Steady States of Open Many-Body Systems
Kazuki Yamamoto, Yuto Ashida, Norio Kawakami
We study how translationally invariant couplings of many-particle systems and nonequilibrium baths can be used to rectify particle currents, for which we consider minimal setups to…

Theory of Non-Hermitian Fermionic Superfluidity with a Complex-Valued Interaction
Kazuki Yamamoto, Masaya Nakagawa, Kyosuke Adachi +3
Motivated by recent experimental advances in ultracold atoms, we analyze a non-Hermitian (NH) BCS Hamiltonian with a complex-valued interaction arising from inelastic scattering be…
