Adiabatic transport in one-dimensional systems with a single defect
Kazuaki Takasan, Masaki Oshikawa, Haruki Watanabe
The adiabatic transport properties of U(1) invariant systems are determined by the dependence of the ground state energy on the twisted boundary condition. We examine a one-dimensi…
Exact results for nonlinear Drude weights in the spin-1/2 XXZ chain
Yuhi Tanikawa, Kazuaki Takasan, Hosho Katsura
Nonlinear Drude weight (NLDW) is a new concept which characterizes the nonlinear transport in quantum many-body systems. We investigate these weights for the spin-1/2 XXZ chain in…
Control of superexchange interactions with DC electric fields
Shunsuke C. Furuya, Kazuaki Takasan, Masahiro Sato
We discuss DC electric-field controls of superexchange interactions. We first present generic results about antiferromagnetic and ferromagnetic superexchange interactions valid in…
Breakdown of Markovianity by interactions in stroboscopic Floquet-Lindblad dynamics under high-frequency drive
Kaoru Mizuta, Kazuaki Takasan, Norio Kawakami
Floquet-Magnus (FM) expansion theory is a powerful tool in periodically driven (Floquet) systems under high-frequency drives. In closed systems, it dictates that their stroboscopic…
Laser-induced topological -wave superconductivity in bilayer transition metal dichalcogenides
Hiroomi Chono, Kazuaki Takasan, Youichi Yanase
In this paper, we propose a way to realize topological -wave superconductivity with application of circularly polarized laser light in two-dimensional bilayer transition metal d…
Anomalous Hydrodynamic Transport in Interacting Noncentrosymmetric Metals
Riki Toshio, Kazuaki Takasan, Norio Kawakami
In highly conductive metals with sufficiently strong momentum-conserving scattering, the electron momentum is regarded as a long-lived quantity, whose dynamics is described by an e…
