Spatial-Translation-Induced Discrete Time Crystals
Kaoru Mizuta, Kazuaki Takasan, Masaya Nakagawa +1
A discrete time crystal is a phase unique to nonequilibrium systems, where discrete time translation symmetry is spontaneously broken. Most of conventional time crystals proposed s…
Control of Magnetic and Topological Orders with a DC Electric Field
Kazuaki Takasan, Masahiro Sato
We theoretically propose a new route to control magnetic and topological orders in a broad class of insulating magnets with a DC electric field. We show from the strong-coupling ex…
Topological phases of non-Hermitian systems
Zongping Gong, Yuto Ashida, Kohei Kawabata +3
Recent experimental advances in controlling dissipation have brought about unprecedented flexibility in engineering non-Hermitian Hamiltonians in open classical and quantum systems…
