Quantum Monte Carlo study of the transverse-field Ising model on a frustrated checkerboard lattice
H. Ishizuka, Y. Motome, N. Furukawa +1
We present the numerical results for low temperature behavior of the transverse-field Ising model on a frustrated checkerboard lattice, with focus on the effect of both quantum and…
Application of polynomial-expansion Monte Carlo method to a spin-ice Kondo lattice model
Hiroaki Ishizuka, Masafumi Udagawa, Yukitoshi Motome
We present the results of Monte Carlo simulation for a Kondo lattice model in which itinerant electrons interact with Ising spins with spin-ice type easy-axis anisotropy on a pyroc…
Quantum Monte Carlo study of the formation of molecular polarizations and the antiferroelectric ordering in squaric acid crystals
Hiroaki Ishizuka, Yukitoshi Motome, Nobuo Furukawa +1
Effects of geometrical frustration and quantum fluctuation are theoretically investigated for the proton ordering in a quasi-two-dimensional hydrogen-bonded system, squaric acid cr…
Metal-insulator transition caused by the coupling to localized charge-frustrated systems under ice-rule local constraint
Hiroaki Ishizuka, Masafumi Udagawa, Yukitoshi Motome
We report the results of our theoretical and numerical study on electronic and transport properties of fermion systems with charge frustration. We consider an extended Falicov-Kimb…
