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…

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…
