Journal ArticleDOI
Quench Dynamics and Orthogonality Catastrophe of Bose Polarons.
TL;DR: The impurity dynamics can be described by an effective potential that deforms from a harmonic to a double-well one when crossing the miscibility-immiscibility threshold and an orthogonality catastrophe occurs and the polaron picture breaks down.
Journal ArticleDOI
Negative-Mass Hydrodynamics in a Spin-Orbit-Coupled Bose-Einstein Condensate.

TL;DR: An expanding spin-orbit coupled Bose-Einstein condensate whose dispersion features a region of negative effective mass is measured, observing a range of dynamical phenomena, including the breaking of parity and of Galilean covariance, dynamical instabilities, and self-trapping.

Journal ArticleDOI
Shaping the evanescent field of optical nanofibers for cold atom trapping
TL;DR: In this article, the authors investigate trapping geometries for cold, neutral atoms that can be created in the evanescent field of a tapered optical fiber by combining the fundamental mode with one of the next lowest possible modes, namely the HE21 mode.
