Efficient Scheme for Time-dependent Thermal Pure Quantum State: Application to the Kitaev Model with Armchair Edges
H. Taguchi, A. Koga, Y. Murakami
We consider the time-dependent thermal pure quantum state method and introduce the efficient scheme to evaluate the change in physical quantities induced by the time-dependent pert…
Field-direction Dependence of Majorana-mediated Spin Transport
H. Taguchi, A. Koga, Y. Murakami +2
We study the field-direction dependence of the Majorana-mediated spin transport in the Kitaev clusters with zigzag and armchair edges, applying a static magnetic field to one of th…
Thermally enhanced Majorana-mediated spin transport in the Kitaev model
Hirokazu Taguchi, Yuta Murakami, Akihisa Koga
We study how stable the Majorana-mediated spin transport in a quantum spin Kitaev model is against thermal fluctuations. Using the time-dependent thermal pure quantum state method,…
Role of Majorana fermions in spin transport of anisotropic Kitaev model
Hirokazu Taguchi, Yuta Murakami, Akihisa Koga +1
We study a quantum spin Kitaev model with zigzag edges to clarify the effects of anisotropy in the exchange couplings on the spin propagation. We simulate the spin and Majorana dyn…
