Majorana-mediated spin transport without spin polarization in Kitaev quantum spin liquids
Tetsuya Minakawa, Yuta Murakami, Akihisa Koga +1
We study the spin transport through the quantum spin liquid (QSL) by investigating the real-time and real-space dynamics of the Kitaev spin system with a zigzag structure in terms…

Magnetic properties of the S = 1 Kitaev model with anisotropic interactions
Tetsuya Minakawa, Joji Nasu, Akihisa Koga
We investigate magnetic properties in the Kitaev model in the anisotropic limit. Performing the fourth-order perturbation expansion with respect to the -bonds, -bonds,…
