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…
Demonstration of geometric diabatic control of quantum states
Kento Sasaki, Yuki Nakamura, Tokuyuki Teraji +2
Geometric effects can play a pivotal role in streamlining quantum manipulation. We demonstrate a geometric diabatic control, that is, perfect tunneling between spin states in a dia…
Anomalous Hall effect of light-driven three-dimensional Dirac electrons in bismuth
Yoshua Hirai, Naotaka Yoshikawa, Masashi Kawaguchi +4
Recent advancement in laser technology has opened the path toward the manipulation of functionalities in quantum materials by intense coherent light. Here, we study three-dimension…
Disentangling the Competing Mechanisms of Light-Induced Anomalous Hall Conductivity in Three-Dimensional Dirac Semimetal
Yuta Murotani, Natsuki Kanda, Tomohiro Fujimoto +7
We experimentally elucidate the origin of the anomalous Hall conductivity in a three-dimensional Dirac semimetal, CdAs, driven by circularly polarized light. Using time-res…
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…
Ellipticity control of terahertz high-harmonic generation in a Dirac semimetal
Semyon Germanskiy, Renato M. A. Dantas, Sergey Kovalev +9
We report on terahertz high-harmonic generation in a Dirac semimetal as a function of the driving-pulse ellipticity and on a theoretical study of the field-driven intraband kinetic…
