Lindbladian reverse engineering for general non-equilibrium steady states: A scalable null-space approach
Leonardo da Silva Souza, Fernando Iemini
The study of open system dynamics is of paramount importance both from its fundamental aspects as well as from its potential applications in quantum technologies. In the simpler an…
Continuous-time open quantum walks in one dimension: matrix-valued orthogonal polynomials and Lindblad generators
Newton Loebens
We study continuous-time open quantum walks in one dimension through a matrix representation, focusing on nearest-neighbor transitions for which an associated weight matrix exists.…
An entropic simulational study of the spin- Baxter-Wu model in a crystal field
L. N. Jorge, P. H. L. Martins, C. J. DaSilva +2
We investigate the critical behavior of the two-dimensional spin- Baxter-Wu model in a crystal field using entropic sampling simulations with the joint density of states. We obt…
Thoroughly analysis of the phase diagram for the Bell-Lavis model: An entropic simulational study
L. S. Ferreira, L. N. Jorge, Cláudio J. DaSilva +1
In this work, we investigate the Bell-Lavis model using entropic simulations for several values of the energy parameters. The phase diagram and the ground state configur…
Real-time Phase Conjugation of Vector Vortex Beams
A. G. de Oliveira, M. F. Z. Arruda, W. C. Soares +4
Vector vortex beams have played a fundamental role in the better understanding of coherence and polarization. They are described by spatially inhomogeneous polarization states, whi…
Phase conjugation and mode conversion in stimulated parametric down-conversion with orbital angular momentum: a geometrical interpretation
André G. de Oliveira, Marcelo F. Z. Arruda, Willamys C. Soares +5
We report on an experiment that investigates the spatial mode conversion in the process of parametric down-conversion seeded by a light beam in a superposition of orbital angular m…
On the order of the phase transition in the spin-1 Baxter-Wu model
L. N. Jorge, L. S. Ferreira, A. A. Caparica
In this work we investigate the order of the phase transition of the spin-1 Baxter-Wu model. We used extensive entropic simulations to describe the behavior of quantities which rev…
The three-dimensional Baxter-Wu Model
L. N. Jorge, L. S. Ferreira, A. A. Caparica
A classic three-dimensional spin model, based upon the Baxter-Wu scheme, is presented. It is found, by entropic sampling simulations, that the behavior of the energy and magnetizat…
Klyshko's Advanced-Wave Picture in Stimulated Parametric Down-Conversion with a Spatially Structured Pump Beam
M. F. Z. Arruda, W. C. Soares, S. P. Walborn +4
The advanced-wave picture is "... an intuitive treatment of two-photon correlation with the help of the concept of an effective field acting upon one of the two detectors and forme…
Thermodynamic properties of rod-like chains: entropic sampling simulations
Lucas S. Ferreira, Lucas N. Jorge, Alvaro A. Caparica +3
In this work we apply entropic sampling simulations to a three-state model which has exact solutions in the microcanonical and grand-canonical ensembles. We consider chains pla…
Critical behavior of the spin- Baxter-Wu model: Entropic sampling simulations
L. N. Jorge, L. S. Ferreira, S. A. Leão +1
In this work we use a refined entropic sampling technique based on the Wang-Landau method to study the spin- Baxter-Wu model. The static critical exponents were determined as…
Dynamical Chern-Simons modified gravity, Godel Universe and variable cosmological constant
C. Furtado, J. R. Nascimento, A. Yu. Petrov +1
We study the condition for the consistency of the Gödel metric with the dynamical Chern-Simons modified gravity. It turns out to be that this compatibility can be achieved only if…
