Muñoz de Nova, Juan Ramón ; Guéry Odelin, D. ; Sols Lucía, Fernando ; Zapata, I. | IOP Publishing | 2014-12-15We 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 protocols that best lead to a quasi-stationary sonic black hole s[...]texto impreso
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 non-classical correlations resulting from the quantum character of the spont[...]texto impreso
Gaul, C. ; Domínguez-Adame Acosta, Francisco ; Sols Lucía, Fernando ; Zapata, I. | American Physical Society | 2014-01-21Two-particle scattering in graphene is a multichannel problem, where the energies of the identical or opposite-helicity channels lie in disjoint energy segments. Due to the absence of Galilean invariance, these segments depend on the total momen[...]texto impreso
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 horizon from which the analogue of Hawking radiation should be gener[...]texto impreso
We devote this work to the study of the mean-field phase diagram of the ? = 0 quantum Hall state in bilayer graphene and the computation of the corresponding neutral collective modes, extending the results of recent works in the literature. Spec[...]texto impreso
We show that antiparallel triplet pairing correlations are generated in superfluids with purely s-wave interactions whenever population imbalance enforces anisotropic Fulde Ferrell (FF) or inhomogeneous Larkin-Ovchinikov (LO) states. These tripl[...]texto impreso
Muñoz de Nova, Juan Ramón ; Sols Lucía, Fernando ; Zapata, I. | American Physical Society | 2014-04-07The 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 particularly large near the peaks in the radiation spectrum emitte[...]
