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 s=1/2 1D antiferromagnetic XXZ model with…

HPC-Driven Modeling with ML-Based Surrogates for Magnon-Photon Dynamics in Hybrid Quantum Systems
Jialin Song, Yingheng Tang, Pu Ren +8
Simulating hybrid magnonic quantum systems remains a challenge due to the large disparity between the timescales of the two systems. We present a massively parallel GPU-based simul…

Geometric Effects on Tunneling in Driven Quantum Systems
Shintaro Takayoshi, Takashi Oka
We review quantum tunneling provoked by external field driving, focusing on the role of geometric effects. The discussion begins with an overview of tunneling phenomena, including…
