DMFT Study for Valence Fluctuations in the Extended Periodic Anderson Model
Ryu Shinzaki, Joji Nasu, Akihisa Koga
We study valence fluctuations at finite temperatures in the extended periodic Anderson model, where the Coulomb interaction between conduction and localized -electrons is taken…
Spin correlation and Majorana spectrum in chiral spin liquids in a decorated-honeycomb Kitaev model
Joji Nasu, Yukitoshi Motome
Temperature evolution of the spin correlation and excitation spectrum is investigated for a Kitaev model defined on a decorated honeycomb lattice by using the quantum Monte Carlo s…
Phase Diagram of the Kitaev-type Model on a Decorated Honeycomb Lattice in the Isolated Dimer Limit
Joji Nasu, Yukitoshi Motome
An effective model in the isolated dimer limit of the Kitaev-type model on a decorated honeycomb lattice is investigated at finite temperature. The ground state of this model is ex…
Thermodynamics of Chiral Spin Liquids with Abelian and Non-Abelian Anyons
Joji Nasu, Yukitoshi Motome
Thermodynamic properties of chiral spin liquids are investigated for a variant of the Kitaev model defined on a decorated honeycomb lattice. Using the quantum Monte Carlo simulatio…
Magnetic three states of matter: A quantum Monte Carlo study of spin liquids
Yoshitomo Kamiya, Yasuyuki Kato, Joji Nasu +1
We present thermodynamic phase diagrams showing magnetic analog of "three states of matter," namely, spin liquid, paramagnetic, and magnetically ordered phases, obtained by unbiase…
Thermal fractionalization of quantum spins in a Kitaev model: -linear specific heat and coherent transport of Majorana fermions
Joji Nasu, Masafumi Udagawa, Yukitoshi Motome
Finite-temperature () properties of a Kitaev model defined on a honeycomb lattice are investigated by a quantum Monte Carlo simulation, from the viewpoint of fractionalization o…
