Temperature dependence of spin currents in one- and three-dimensional insulators
Kouki Nakata
The temperature dependence of spin currents in insulators at the finite temperature near zero Kelvin is theoretically studied. The spin currents are carried by Jordan-Wigner fermio…

Magnon Pumping by a Time-Dependent Transverse Magnetic Field in Ferromagnetic Insulators
Kouki Nakata, Gen Tatara
The magnon pumping effect in ferromagnetic insulators under an external time-dependent transverse magnetic field is theoretically studied. Generation of a magnon current is discuss…

Extended Quantum Dimer Model and novel valence-bond phases
Kouki Nakata, Keisuke Totsuka
We extend the quantum dimer model (QDM) introduced by Rokhsar and Kivelson so as to construct a concrete example of the model which exhibits the first-order phase transition betwee…
