Cross derivative: a universal and efficient method for phase transitions in classical spin models
Y. Chen, K. Ji, Z. Y. Xie +1
With an auxiliary weak external magnetic field, we reexamine the fundamental thermodynamic function, Gibbs free energy F(T, h), to study the phase transitions in the classical spin…
Unveiling the quantum critical point of an Ising chain
Y. F. Dai, H. Zhang, S. Y. Zhou +7
Quantum phase transitions occur at zero temperature upon variation of some nonthermal control parameters. The Ising chain in a transverse field is probably the most-studied model u…
Bosonization study of quantum phase transitions in the one-dimensional asymmetric Hubbard model
Z. G. Wang, Y. G. Chen, S. J. Gu
The quantum phase transitions in the one-dimensional asymmetric Hubbard model are investigated with the bosonization approach. The conditions for the phase transition from density…
Near-Perfect Correlation of the Resistance Components of Mesoscopic Samples at the Quantum Hall Regime
E. Peled, D. Shahar, Y. Chen +3
We study the four-terminal resistance fluctuations of mesoscopic samples near the transition between the and the quantum Hall states. We observe near-perfect correlatio…
Distribution function for shotnoise in disordered multi-channel quantum conductors
K A Muttalib, Y Chen
We obtain the shot noise generating function for a multi-channel quantum conductor in the diffusive limit.
Crossover from Fermi Liquid to Non-Fermi Liquid Behavior in a Solvable One-Dimensional Model
Y. Chen, K. A. Muttalib
We consider a quantum moany-body problem in one-dimension described by a Jastrow type, characterized by an exponent and a parameter . We show that with increasing , the F…
