Activity-induced ferromagnetism in one-dimensional quantum many-body systems
Kazuaki Takasan, Kyosuke Adachi, Kyogo Kawaguchi
We study a non-Hermitian quantum many-body model in one dimension analogous to the Vicsek model or active spin models, and investigate its quantum phase transitions. The model cons…
Light-field-driven non-Ohmic current and Keldysh crossover in a Weyl semimetal
R. Ikeda, H. Watanabe, J. H. Moon +3
In recent years, coherent electrons driven by light fields have attracted significant interest in exploring novel material phases and functionalities. However, observing coherent l…
Patchwork Conditions for Holographic Nonlinear Responses: A Computational Method for Electric Conductivity and Friction Coefficient
Shuta Ishigaki, Shin Nakamura, Kazuaki Takasan
We propose a new method to compute nonlinear transport coefficients in holography, such as nonlinear DC conductivity and nonlinear friction coefficient. The conventional method can…
