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…
Variational Monte Carlo Study of Electron Differentiation around Mott Transition
Daisuke Tahara, Masatoshi Imada
We study ground-state properties of the two-dimensional Hubbard model at half filling by improving variational Monte Carlo method and by implementing quantum-number projection and…
Variational Monte Carlo Method Combined with Quantum-Number Projection and Multi-Variable Optimization
Daisuke Tahara, Masatoshi Imada
Variational wave functions used in the variational Monte Carlo (VMC) method are extensively improved to overcome the biases coming from the assumed variational form of the wave fun…
YbRh2Si2: Quantum tricritical behavior in itinerant electron systems
Takahiro Misawa, Youhei Yamaji, Masatoshi Imada
We propose that proximity of the first-order transition manifested by the quantum tricritical point (QTCP) explains non-Fermi-liquid properties of YbRh2Si2. Here, at the QTCP, a co…
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…
Does Simple Two-Dimensional Hubbard Model Account for High-Tc Superconductivity in Copper Oxides?
Takeshi Aimi, Masatoshi Imada
We reexamine whether the essence of high-Tc superconductivity is contained in doped Hubbard models on the square lattice by using recently developed pre-projected Gaussian-basis Mo…
