Three-dimensional Gross-Pitaevskii solitary waves in optical lattices: stabilization using the artificial quartic kinetic energy induced by lattice shaking
M. Olshanii, S. Choi, V. Dunjko +4
In this Letter, we show that a three-dimensional Bose-Einstein solitary wave can become stable if the dispersion law is changed from quadratic to quartic. We suggest a way to reali…
Monopole excitations of a harmonically trapped one-dimensional Bose gas from the ideal gas to the Tonks-Girardeau regime
S. Choi, V. Dunjko, Z. D. Zhang +1
Using a time-dependent modified nonlinear Schrödinger equation (m-NLSE) -- where the conventional chemical potential proportional to the density is replaced by the one inferred fro…
Breakdown of the scale invariance in the vicinity of Tonks-Girardeau gas
Z. D. Zhang, G. E. Astrakharchik, D. C. Aveline +4
In this article, we consider the monopole excitations of the harmonically trapped Bose gas in the vicinity of the Tonks-Girardeau limit. Using Girardeau's Fermi-Bose duality and su…
Single-photon cooling in a wedge billiard
S. Choi, B. Sundaram, M. G. Raizen
Single-Photon Cooling (SPC), noted for its potential as a versatile method for cooling a variety of atomic species, has recently been demonstrated experimentally. In this paper, we…
A quantum description of bubble growth in a superheated fluid
S. Choi, K. M. Galdamez, B. Sundaram
We discuss a quantum description of bubble growth in a superheated liquid Helium by addressing the problem of operator ordering ambiguities that arise due to the presence of positi…
Quantum non-demolition measurements using Bose-Einstein condensates
S. Choi, K. Burnett
We study possible scenarios for quantum non-demolition measurements using Bose-Einstein condensates. We show that the interactions between condensate atoms makes it possible to mea…
