Angular Dependence of Specific Heat and Magnetization Effects in the Kitaev Model
Takao Morinari, Hibiki Takegami
We investigate the effect of a magnetic field on the Kitaev model using the equation of motion approach for the spin Green's function, considering both the case of suppressed magne…

Spin-Spin Correlations in the Kitaev Model at Finite Temperatures: Approximate and Exact Results via Green's Function Equation of Motion
Hibiki Takegami, Takao Morinari
The Kitaev model, defined on a honeycomb lattice, features an exactly solvable ground state with fractionalized Majorana fermion excitations, which can potentially form non-Abelian…
