Quantum phase transitions and critical behaviors in the two-mode three-level quantum Rabi model
Yan Zhang, Bin-Bin Mao, Dazhi Xu +4
We explore an extended quantum Rabi model describing the interaction between a two-mode bosonic field and a three-level atom. Quantum phase transitions of this few degree of freedo…
Weakly first-order phase transitions: the epsilon expansion vs. numerical simulations
Peter Arnold, Stephen R. Sharpe, Laurence G. Yaffe +1
Some phase transitions of cosmological interest may be weakly first-order and cannot be analyzed by a simple perturbative expansion around mean field theory. We propose a simple tw…
expansion analysis of very weak first-order transitions in the cubic anisotropy model, Part II
Peter Arnold, Yan Zhang
A companion article analyzed very weakly first-order phase transitions in the cubic anisotropy model using $\eps$ expansion techniques. We extend that analysis to a calculation of…
Monte Carlo study of very weak first-order transitions in the three-dimensional Ashkin-Teller model
Peter Arnold, Yan Zhang
We propose numerical simulations of the Ashkin-Teller model as a foil for theoretical techniques for studying very weakly first-order phase transitions in three dimensions. The Ash…
