Floquet Theory and Ultrafast Control of Magnetism
Masahiro Sato
The development of laser science and technology have stimulated the study of condensed matter physics, especially, dynamical or non-equilibrium nature in solids. The laser techniqu…
Large photogalvanic spin current by magnetic resonance in bilayer Cr trihalides
Hiroaki Ishizuka, Masahiro Sato
Magnetic materials show rich optical responses related to the magnetic order. These phenomena reflect the nature of their excitations, providing a powerful probe for the magnetic s…
Electric-field control of magnetic anisotropies: applications to Kitaev spin liquids and topological spin textures
Shunsuke C. Furuya, Masahiro Sato
Magnetic anisotropies often originate from the spin-orbit coupling and determine magnetic ordering patterns. We develop a microscopic theory for DC electric-field controls of magne…
Triplon current generation in solids
Yao Chen, Masahiro Sato, Yifei Tang +6
A triplon refers to a fictitious particle that carries angular momentum corresponding to the elementary excitation in a broad class of quantum dimerized spin systems. Such…
Quantized edge magnetizations and their symmetry protection in one-dimensional quantum spin systems
Shunsuke C. Furuya, Masahiro Sato
The bulk electric polarization works as a nonlocal order parameter that characterizes topological quantum matters. Motivated by a recent paper [H. Watanabe \textit{et al.}, Phys. R…
Nonequilibrium steady states in the Floquet-Lindblad systems: van Vleck's high-frequency expansion approach
Tatsuhiko N. Ikeda, Koki Chinzei, Masahiro Sato
Nonequilibrium steady states (NESSs) in periodically driven dissipative quantum systems are vital in Floquet engineering. We develop a general theory for high-frequency drives with…
