Entropy of a Turbulent Bose-Einstein Condensate
Lucas Madeira, Arnol D. García-Orozco, F. E. A. dos Santos +1
Quantum turbulence deals with the phenomenon of turbulence in quantum fluids, such as superfluid helium and trapped Bose-Einstein condensates (BECs). Although much progress has bee…
Quantum turbulence in Bose-Einstein condensates: present status and new challenges ahead
L. Madeira, A. Cidrim, M. Hemmerling +3
The field of quantum turbulence is related to the manifestation of turbulence in quantum fluids, such as liquid helium and ultracold gases. The concept of turbulence in quantum sys…
Bose-Einstein Condensation on Curved Manifolds
Natália S. Móller, F. Ednilson A. dos Santos, Vanderlei S. Bagnato +1
Here we describe a weakly interacting Bose gas on a curved manifold, which is embedded in the three-dimensional Euclidean space.~To this end we start by considering a harmonic trap…
Cooperative spontaneous emission via renormalization approach: Classical versus semi-classical effects
Carlos Eduardo Máximo, Romain Bachelard, Francisco Ednilson Alves dos Santos +1
We address the many-atom emission of a dilute cloud of two-level atoms through a renormalized perturbation theory. An analytical solution for the truncated coupled-dipole equations…
Quantum turbulence in quantum gases
L. Madeira, M. A. Caracanhas, F. E. A. dos Santos +1
Turbulence is characterized by a large number of degrees of freedom, distributed over several length scales, that result into a disordered state of a fluid. The field of quantum tu…
Free expansion of Bose-Einstein condensates with a multicharged vortex
Rafael Poliseli Teles, F. E. A. dos Santos, M. A. Caracanhas +1
In this work, we analyze the free expansion of Bose-Einstein condensates containing multicharged vortices. The atomic cloud is initially confined in a three-dimensional asymmetric…
