Phase transitions on the dark side of the Gross-Neveu model: Spontaneous symmetry breaking at repulsive coupling
Gabriel Osiander Rein, Fakher F. Assaad, Igor F. Herbut
Gross-Neveu model in 2+1 dimensions exhibits a continuous transition from gapless Dirac semimetal to the gapped quantum anomalous Hall (QAH) insulator at a finite (attractive) coup…
The two-dimensional optical Su-Schrieffer-Heeger model: ground state and thermodynamic properties
Jadson L. Portela e Silva, Gabriel Rein, Sebastião dos A. Sousa-Júnior +2
We investigate the two-dimensional optical Su-Schrieffer-Heeger (SSH) model, in which the electron hopping amplitude is modulated by the difference between neighboring phonon coord…
Alteration of Topology in Quantum Phase Transitions via Symmetry Enrichment
Gabriel Rein, Marcin Raczkowski, Zhenjiu Wang +2
Topology plays a cardinal role in explaining phases and quantum phase transitions beyond the Landau-Ginzburg-Wilson paradigm. In this study, we formulate a set of models of Dirac f…
Hubbard and Heisenberg models on hyperbolic lattices: Metal-insulator transitions, global antiferromagnetism, and enhanced boundary fluctuations
Anika Götz, Gabriel Rein, João Carvalho Inácio +1
We study the Hubbard and Heisenberg models on hyperbolic lattices with open boundary conditions by means of mean-field approximations, spin-wave theory, and quantum Monte Carlo (QM…
Entanglement robustness to excitonic spin precession in a quantum dot
Samir Bounouar, Gabriel Rein, Kisa Barkemeyer +9
A semiconductor quantum dot (QD) is an attractive resource to generate polarization-entangled photon pairs. We study the excitonic spin precession (flip-flop) in a family of QDs wi…
