Topological Superconductor from the Quantum Hall Phase: Effective Field Theory Description
M. Gomes, Pedro R. S. Gomes, K. Raimundo +2
We derive low-energy effective field theories for the quantum anomalous Hall and topological superconducting phases. The quantum Hall phase is realized in terms of free fermions wi…
Quantum Spherical Spins with Local Symmetry
Pedro R. S. Gomes, P. F. Bienzobaz
We construct a quantum system of spherical spins with a continuous local symmetry. The model is exactly soluble in the thermodynamic limit and exhibits a number of interesting prop…
Effective field theory for the bulk-edge correspondence in a two-dimensional Z_2 topological insulator with Rashba interactions
Pedro R. S. Gomes, Po-Hao Huang, Claudio Chamon +1
We determine the effective field theory in (2+1)-dimensional space and time that captures the long wave length and low-energy limit of fermions hopping on a honeycomb lattice at ha…
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…
