From classical to quantum loss of light coherence
Pierre Lassègues, Mateus Antônio Fernandes Biscassi, Martial Morisse +7
Light is a precious tool to probe matter, as it captures microscopic and macroscopic information on the system. We here report on the transition from a thermal (classical) to a spo…
Field and intensity correlations: the Siegert relation from stars to quantum emitters
Pierre Lassègues, Mateus Antônio Fernandes Biscassi, Martial Morisse +9
The Siegert relation relates field and intensity temporal correlations. After a historical review of the Siegert relation and the Hanbury Brown and Twiss effect, we discuss the val…
Generating long-lived entangled states with free-space collective spontaneous emission
Alan C. Santos, André Cidrim, Celso J. Villas-Boas +2
Considering the paradigmatic case of a cloud of two-level atoms interacting through common vacuum modes, we show how cooperative spontaneous emission, which is at the origin of sup…
Universal dynamics of a turbulent superfluid Bose gas
A. D. García-Orozco, L. Madeira, M. A. Moreno-Armijos +6
We study the emergence of universal scaling in the time-evolving momentum distribution of a harmonically trapped three-dimensional Bose-Einstein condensate, parametrically driven t…
Dipole-dipole frequency shifts in multilevel atoms
A. Cidrim, A. Piñeiro Orioli, C. Sanner +4
Dipole-dipole interactions lead to frequency shifts that are expected to limit the performance of next-generation atomic clocks. In this work, we compute dipolar frequency shifts a…
Soliton trains after interaction quenches in Bose mixtures
A. Cidrim, L. Salasnich, T. Macrì
We investigate the quench dynamics of a two-component Bose mixture and study the onset of modulational instability, which leads the system far from equilibrium. Analogous to the si…
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…
Momentum distribution of Vinen turbulence in trapped atomic Bose-Einstein condensates
Áttis V. M. Marino, Lucas Madeira, André Cidrim +2
The decay of multicharged vortices in trapped Bose-Einstein condensates may lead to a disordered vortex state consistent with the Vinen regime of turbulence, characterized by an ab…
Photon blockade with ground-state neutral atoms
A. Cidrim, T. S. do Espirito Santo, J. Schachenmayer +2
We show that induced dipole-dipole interactions allow for photon blockade in subwavelength ensembles of two-level, ground-state neutral atoms. Our protocol relies on the energy shi…
Vortices in self-bound dipolar droplets
André Cidrim, Francisco E. A. dos Santos, Emanuel A. L. Henn +1
Quantized vortices have been observed in a variety of superfluid systems, from He to condensates of alkali-metal bosons and ultracold Fermi gases along the BEC-BCS crossover. I…
Vinen turbulence via the decay of multicharged vortices in trapped atomic Bose-Einstein condensates
A. Cidrim, A. J. Allen, A. C. White +2
We investigate a procedure to generate turbulence in a trapped Bose-Einstein condensate which takes advantage of the decay of multicharged vortices. We show that the resulting sing…
Quantum turbulence in trapped atomic Bose-Einstein condensates
Marios C. Tsatsos, Pedro E. S. Tavares, Andre Cidrim +5
Turbulence, the complicated fluid behavior of nonlinear and statistical nature, arises in many physical systems across various disciplines, from tiny laboratory scales to geophysic…
Controlled polarization of two-dimensional quantum turbulence in atomic Bose-Einstein condensates
A. Cidrim, F. E. A. dos Santos, L. Galantucci +2
We propose a scheme for generating two-dimensional turbulence in harmonically trapped atomic condensates with the novelty of controlling the polarization (net rotation) of the turb…
Twisted unwinding of multi-charged quantum vortex and generation of turbulence in atomic Bose-Einstein condensates
G. D. Telles, P. E. S. Tavares, A. R. Fritsch +5
We report the observation of the twisted decay of quadruply charged vortices in an atomic Bose-Einstein condensate. Supporting numerical simulations show that the singly-charged vo…
Internal Decoherence of a Gaussian Wave Packet in a Harmonic Potential
A. Cidrim, F. E. A. dos Santos, A. O. Caldeira
We have studied the quantum dissipative problem of a Gaussian wave packet under the influence of a harmonic potential. A phenomenological approach to dissipation is adopted in the…
