Geometric modulation of transition and survival intensities in non-Hermitian systems
Ryu Frieson, Takashi Oka, Hideaki Obuse
The time evolution of non-Hermitian systems is generally nonunitary. Dynamics governed by time-dependent non-Hermitian Hamiltonians lead to a variety of novel phenomena, one of whi…

Light-induced anomalous Hall conductivity in massive 3D Dirac semimetal CoSnS
Naotaka Yoshikawa, Shun Okumura, Yoshua Hirai +10
Weyl semimetals can emerge from Dirac semimetals when the time-reversal or spatial-inversion symmetries are broken. Recently, it has been proposed based on the Floquet theory that…
