Direct derivation of microcanonical ensemble average from many-particle quantum mechanics
Tetsuro Saso
Starting from the quantum mechanics for particles, we show that we can directly derive the microcanonical ensemble average of the physical quantity by using only the long t…
Specific Heat-Coefficient of YbAl3 Studied by Combined Nearly Free Electron Conduction Band Hybridized with Localized f Electrons with Correlation Effect
Yoshiki Imai, Tetsuro Saso
Based on the recently proposed band model, the electronic specific heat of moderately heavy electron compound YbAl are investigated. The band term of the Hamiltonian consists o…
Theory for Magnetic Anisotropy of Field-Induced Insulator-to-Metal Transition in Cubic Kondo Insulator YbB_{12}
Toshiyuki Izumi, Yoshiki Imai, Tetsuro Saso
Magnetization and energy gap of Kondo insulator YbB_{12} are calculated theoretically based on the previously proposed tight-binding model composed of Yb 5d and 4f orbital…
Absence of Hybridization Gap in Heavy Electron Systems and Analysis of YbAl3 in terms of Nearly Free Electron Conduction Band
Hiroyuki Kuroiwa, Yoshiki Imai, Tetsuro Saso
In the analysis of the heavy electron systems, theoretical models with c-f hybridization gap are often used. We point out that such a gap does not exist and the simple picture with…
Anomalous magnetic phase diagram in low-carrier two-band systems and possible application to CeOs4Sb12
Yoshiki Imai, Tetsuro Saso
Magnetic properties under the external field are investigated in low-carrier two-band systems, which may explain the nontrivial phase boundary found in temperature vs. magnetic fie…
Anomalous Metal-Insulator Transition in Filled Skutterudite CeOsSb
Yoshiki Imai, Keitaro Sakurazawa, Tetsuro Saso
Anomalous metal-insulator transition observed in filled skutterudite CeOsSb is investigated by constructing the effective tight-binding model with the Coulomb repulsion…
