Multiple non-hermitian phase transitions on quantum torus surface
José A. S. Lourenço, Ygor Pará, J. Furtado
In this paper we investigate the arising of non-hermitian phase transitions on quantum torus surfaces. We consider a single fermion whose dynamics is governed by the Dirac equation…
Robust quantum boomerang effect in non-Hermitian systems
Flavio Noronha, José A. S. Lourenço, Tommaso Macrì
Anderson localization is a general phenomenon that applies to a variety of disordered physical systems. Recently, a novel manifestation of Anderson localization for wave packets la…
Non-Hermitian dynamics and -symmetry breaking in interacting mesoscopic Rydberg platforms
José A. S. Lourenço, Gerard Higgins, Chi Zhang +2
We simulate the dissipative dynamics of a mesoscopic system of long-range interacting particles which can be mapped into non-Hermitian spin models with a symmetry. W…
The effect of boundary conditions on dimensionally reduced field-theoretical models at finite temperature
E. Cavalcanti, C. A. Linhares, J. A. Lourenço +1
Here we understand \textit{dimensional reduction} as a procedure to obtain an effective model in dimensions that is related to the original model in dimensions. To explor…
Dimensional reduction of a finite-size scalar field model at finite temperature
E. Cavalcanti, J. A. Lourenço, C. A. Linhares +1
We investigate the process of dimensional reduction of one spatial dimension in a thermal scalar field model defined in dimensions (inverse temperature and spatial dimens…
Kondo effect in a parity-time-symmetric non-Hermitian Hamiltonian
Jose A. S. Lourenco, Ronivon L. Eneias, Rodrigo G. Pereira
The combination of non-Hermitian physics and strong correlations can give rise to new effects in open quantum many-body systems with balanced gain and loss. We propose a generalize…
