Spontaneous Symmetry Breaking and Frustrated Phases
Heitor Casasola, Carlos A. Hernaski, Pedro R. S. Gomes +1
We study a system involving a single quantum degree of freedom per site of the lattice interacting with a few neighbors (up to second neighbors), with the interactions chosen as to…
Supersymmetric Quantum Spherical Spins with Short-Range Interactions
L. V. T. Tavares, L. G. dos Santos, G. T. Landi +2
This work is dedicated to the study of a supersymmetric quantum spherical spin system with short-range interactions. We examine the critical properties both a zero and finite tempe…
Supersymmetric Quantum Spherical Spins
L. G. dos Santos, L. V. T. Tavares, P. F. Bienzobaz +1
In this work we investigate properties of a supersymmetric extension of the quantum spherical model from an off-shell formulation directly in the superspace. This is convenient to…
Modulated phases in a three-dimensional Maier-Saupe model with competing interactions
P. F. Bienzobaz, Na Xu, Anders W. Sandvik
This work is dedicated to the study of the discrete version of the Maier-Saupe model in the presence of competing interactions. The competition between interactions favoring differ…
Stochastic Quantization of the Spherical Model and Supersymmetry
P. F. Bienzobaz, Pedro R. S. Gomes, M. Gomes
We use the stochastic quantization method to construct a supersymmetric version of the quantum spherical model. This is based on the equivalence between the Brownian motion describ…
Supersymmetric Extension of the Quantum Spherical Model
Pedro R. S. Gomes, P. F. Bienzobaz, M. Gomes
In this work, we present a supersymmetric extension of the quantum spherical model, both in components and also in the superspace formalisms. We find the solution for short/long ra…
Quantum spherical model with competing interactions
P. F. Bienzobaz, S. R. Salinas
We analyze the phase diagram of a quantum mean spherical model in terms of the temperature , a quantum parameter , and the ratio , where refers to f…
