Semiclassical and Quantum Black Holes and their Evaporation, de Sitter and Anti-de Sitter Regimes, Gravitational and String Phase Transitions
Marina Ramon Medrano, Norma G. Sanchez
An effective string theory in physically relevant cosmological and black hole space times is reviewed. Explicit computations of the quantum string entropy, partition function and q…
Metallic phase in the two-dimensional ionic Hubbard model
K. Bouadim, N. Paris, F. Hebert +2
We investigate the phases of the ionic Hubbard model in a two-dimensional square lattice using determinant quantum Monte Carlo (DQMC). At half-filling, when the interaction strengt…
Quantum Monte Carlo Study of an Interaction-Driven Band Insulator to Metal Transition
N. Paris, K. Bouadim, F. Hebert +2
We study the transitions from band insulator to metal to Mott insulator in the ionic Hubbard model on a two dimensional square lattice using determinant Quantum Monte Carlo. Evalua…
Mott and Band Insulator Transitions in the Binary Alloy Hubbard Model
N. Paris, A. Baldwin, R. T. Scalettar
We use determinant Quantum Monte Carlo simulations and exact diagonalization to explore insulating behavior in the Hubbard model with a bimodal distribution of randomly positioned…
