Emergent induction in magnetic Weyl semimetals

Takahiro Anan, Takahiro Morimoto

We theoretically study emergent electromagnetic responses in Weyl semimetals. Focusing on magnetic Weyl semimetals, we develop a general theory of emergent induction driven by magn…

Quantum-geometric shift of quasiequilibrium: Origin of nonreciprocal current driven by quantum-metric dipole

Sota Kitamura, Takahiro Anan, Takahiro Morimoto

We study nonlinear DC electric transport of quantum-metric origin by combining adiabatic perturbation theory with the nonequilibrium Green function approach. The adiabatic ansatz p…

Spinon shift current in a noncentrosymmetric quantum spin chain

Ryosuke Yamashita, Shintaro Takayoshi, Takahiro Morimoto

We theoretically study direct current generation in a quantum spin chain induced by spinon excitations by light irradiation. We consider a one-dimensional (1D) antiferromag…

Nonreciprocal current induced by dissipation in time-reversal symmetric systems

Takahiro Anan, Sota Kitamura, Takahiro Morimoto

We study nonreciprocal current response in noncentrosymmetric crystals under time-reversal symmetry. We reveal that the nonreciprocal current appears in a dissipative system throug…

Formulation of the orbital magnetic moment in multiorbital tight-binding models: Application to the inverse Faraday effect

Kosuke Tazuke, Takahiro Morimoto, Sota Kitamura

We establish a theoretical formulation of the orbital magnetic moment in multiorbital tight-binding models, focusing on the role of the electric dipole. We demonstrate that the tot…

Quantum Optical Spanner: Twisting Superconductors with Vortex Beam via Higgs Mode

Daemo Kang, Sota Kitamura, Takahiro Morimoto

Light carrying orbital angular momentum (OAM)--known as vortex beams--has broadened the scope of understanding and applications of light's angular momentum. Optical tweezers using…
