Few-body bound states of two-dimensional bosons
G. Guijarro, G. E. Astrakharchik, J. Boronat +2
We study clusters of the type AB with in a two-dimensional mixture of A and B bosons, with attractive AB and equally repulsive AA and BB interactions. In or…
Quantum phases and collective excitations of a spin-orbit-coupled Bose-Einstein condensate in a one-dimensional optical lattice
Giovanni I. Martone
The ground state of a spin-orbit-coupled Bose gas in a one-dimensional optical lattice is known to exhibit a mixed regime, where the condensate wave function is given by a superpos…
Departing from thermality of analogue Hawking radiation in a Bose-Einstein condensate
M. Isoard, N. Pavloff
We study the quantum fluctuations in a one dimensional Bose-Einstein condensate realizing an analogous acoustic black hole. The taking into account of evanescent channels and of ze…
Three-body interaction near a narrow two-body zero crossing
A. Pricoupenko, D. S. Petrov
We calculate the effective three-body force for bosons interacting with each other by a two-body potential tuned to a narrow zero crossing in any dimension. We use the standard two…
Enhancement of many-body quantum interference in chaotic bosonic systems
Peter Schlagheck, Denis Ullmo, Juan Diego Urbina +2
Although highly successful, the truncated Wigner approximation (TWA) leaves out many-body quantum interference between mean-field Gross-Pitaevskii solutions as well as other quantu…
Fusion channels of non-Abelian anyons from angular-momentum and density-profile measurements
Elia Macaluso, Tommaso Comparin, Leonardo Mazza +1
We present a method to characterize non-Abelian anyons that is based only on static measurements and that does not rely on any form of interference. For geometries where the anyoni…
