Resonant analogue configurations in atomic condensates
Juan Ramón Muñoz de Nova, Pablo Fernández Palacios, Pedro Alcázar Guerrero +2
As a contribution to a memorial volume, we provide a comprehensive discussion of resonant configurations in analogue gravity, focusing on its implementation in atomic condensates a…
Quantum transport in the black-hole configuration of an atom condensate outcoupled through an optical lattice
J. R. M. de Nova, F. Sols, I. Zapata
The outcoupling of a Bose-Einstein condensate through an optical lattice provides an interesting scenario to study quantum transport phenomena or the analog Hawking effect as the s…
Entanglement and violation of classical inequalities in the Hawking radiation of flowing atom condensates
J. R. M. de Nova, F. Sols, I. Zapata
We consider a sonic black-hole scenario where an atom condensate flows through a subsonic-supersonic interface. We discuss several criteria that reveal the existence of nonclassica…
Birth of a quasi-stationary black hole in an outcoupled Bose-Einstein condensate
J. R. M. de Nova, D. Guéry-Odelin, F. Sols +1
We study the evolution of an initially confined atom condensate which is progressively outcoupled by gradually lowering the confining barrier on one side. The goal is to identify p…
Violation of Cauchy-Schwarz inequalities by spontaneous Hawking radiation in resonant boson structures
J. R. M. de Nova, F. Sols, I. Zapata
The violation of a classical Cauchy-Schwarz (CS) inequality is identified as an unequivocal signature of spontaneous Hawking radiation in sonic black holes. This violation can be p…
Triplet pair correlations in {\it s-}wave superfluids as a signature of the FFLO state
I. Zapata, F. Sols, E. Demler
We show that triplet pairing correlations are generated in purely s-waves superfluids whenever population imbalance enforces anisotropic Fulde-Ferrell (FF) or inhomogeneous Larkin-…
Resonant Hawking radiation in Bose-Einstein condensates
Ivar Zapata, Mathias Albert, Renaud Parentani +1
We study double-barrier interfaces separating regions of asymptotically subsonic and supersonic flow of Bose condensed atoms. These setups contain at least one black hole sonic hor…
Pi-phases in balanced fermionic superfluids on spin-dependent optical lattices
I. Zapata, B. Wunsch, N. T. Zinner +1
We study a balanced two-component system of ultracold fermions in one dimension with attractive interactions and subject to a spin-dependent optical lattice potential of opposite s…
