Enhancement of Nuclear Spin-Lattice Relaxation Rate and Spin Susceptibility due to Valence Fluctuations -Origin of Anomalously Enhanced Wilson Ratio in Ce and Yb Systems-
Shinji Watanabe, Kazumasa Miyake
We show theoretically that the nuclear spin-lattice relaxation rate (T_1T)^{-1} and the spin susceptibility exhibit divergent behaviors toward zero temperature at the quantum criti…
Valence Fluctuations Revealed by Magnetic Field Scan: Comparison with Experiments in YbXCu_4 (X=In, Ag, Cd) and CeYIn_5 (Y=Ir, Rh)
Shinji Watanabe, Atsushi Tsuruta, Kazumasa Miyake +1
The mechanism of how critical end points of the first-order valence transitions (FOVT) are controlled by a magnetic field is discussed. We demonstrate that the critical temperature…
Comment on arXiv:0811.1575 entitled "Quantum phase transitions in the Hubbard model on triangular lattice" by T. Yoshioka, A. Koga and N. Kawakami
Shinji Watanabe, Takahiro Mizusaki, Masatoshi Imada
We show that the phase boundary between the paramagnetic metal and the nonmagnetic Mott insulator for the Hubbard model on a triangular lattice obtained by Yoshioka et al. in arXiv…
On Proximity of 4/7 Solid Phase of 3He Adsorbed on Graphite -Origin of Specific-Heat Anomalies in Hole-Doped Density-Ordered Solid-
Shinji Watanabe, Masatoshi Imada
We theoretically study the stability of the solidified second-layer 3He at 4/7 of the first-layer density adsorbed on graphite, which exhibits quantum spin liquid. We construct a l…
Magnetic-Field Control of Quantum Critical Points of Valence Transition
Shinji Watanabe, Atsushi Tsuruta, Kazumasa Miyake +1
We study the mechanism how critical end points of first-order valence transitions are controlled by a magnetic field. We show that the critical temperature is suppressed to be a qu…
What is Minimal Model of 3He Adsorbed on Graphite? -Importance of Density Fluctuations in 4/7 Registered Solid -
Shinji Watanabe, Masatoshi Imada
We show theoretically that the second layer of 3He adsorbed on graphite and solidified at 4/7 of the first-layer density is close to the fluid-solid boundary with substantial densi…
