Interplay of Spin-Orbit Interaction and Electron Correlation on the Van Vleck Susceptibility in Transition Metal Compounds
Masafumi Udagawa, Youichi Yanase
We have studied the effects of electron correlation on Van Vleck susceptibility () in transition metal compounds. A typical crossover behavior is found for the correla…
Partial Kondo screening in frustrated Kondo lattice systems
Yukitoshi Motome, Kyoya Nakamikawa, Youhei Yamaji +1
We investigate the effect of geometrical frustration on the competition between the Kondo coupling and the Ruderman-Kittel-Kasuya-Yosida interaction in Kondo lattice systems. By va…
Quantum melting of charge ice and non-Fermi-liquid behavior: An exact solution for the extended Falicov-Kimball model in the ice-rule limit
Masafumi Udagawa, Hiroaki Ishizuka, Yukitoshi Motome
An exact solution is obtained for a model of itinerant electrons coupled to ice-rule variables on the tetrahedron Husimi cactus, an analogue of the Bethe lattice of corner-sharing…
Cluster dynamical mean-field study of the Hubbard model on a 3D frustrated hyperkagome lattice
Masafumi Udagawa, Yukitoshi Motome
We study the Hubbard model on a geometrically-frustrated hyperkagome lattice by a cluster extension of the dynamical mean field theory. We calculate the temperature () dependenc…
Chirality-spin separation in the Hubbard model on the kagome lattice
Masafumi Udagawa, Yukitoshi Motome
Effect of geometrical frustration in strongly-correlated metallic region is studied for the Hubbard model on the kagome lattice at half filling by a cluster extension of the dynami…
Chirality-driven mass enhancement in the kagome Hubbard model
Masafumi Udagawa, Yukitoshi Motome
We investigate the quasiparticle-mass enhancement in the Hubbard model on the frustrated kagome lattice by using a cluster extension of the dynamical mean-field theory. By analyzin…
