Many-body physics with ultracold gases

I Bloch, J Dalibard, W Zwerger - Reviews of modern physics, 2008 - APS
This paper reviews recent experimental and theoretical progress concerning many-body
phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling …

Pattern forming dynamical instabilities of Bose–Einstein condensates

PG Kevrekidis, DJ Frantzeskakis - Modern Physics Letters B, 2004 - World Scientific
In this short topical review, we revisit a number of works on the pattern-forming dynamical
instabilities of Bose–Einstein condensates in one-and two-dimensional settings. In …

Hysteresis in a quantized superfluid 'atomtronic'circuit

S Eckel, JG Lee, F Jendrzejewski, N Murray, CW Clark… - Nature, 2014 - nature.com
Atomtronics, is an emerging interdisciplinary field that seeks to develop new functional
methods by creating devices and circuits where ultracold atoms, often superfluids, have a …

[图书][B] Twisted photons: applications of light with orbital angular momentum

JP Torres, L Torner - 2011 - books.google.com
This book deals with applications in several areas of science and technology that make use
of light which carries orbital angular momentum. In most practical scenarios, the angular …

Quantized vortices in an exciton–polariton condensate

KG Lagoudakis, M Wouters, M Richard, A Baas… - Nature physics, 2008 - nature.com
One of the most striking quantum effects in an interacting Bose gas at low temperature is
superfluidity. First observed in liquid 4He, this phenomenon has been intensively studied in …

Polariton superfluids reveal quantum hydrodynamic solitons

A Amo, S Pigeon, D Sanvitto, VG Sala, R Hivet… - Science, 2011 - science.org
A quantum fluid passing an obstacle behaves differently from a classical one. When the flow
is slow enough, the quantum gas enters a superfluid regime, and neither whirlpools nor …

Driving phase slips in a superfluid atom circuit with a rotating weak link

KC Wright, RB Blakestad, CJ Lobb, WD Phillips… - Physical review …, 2013 - APS
We have observed well-defined phase slips between quantized persistent current states
around a toroidal atomic (Na 23) Bose-Einstein condensate. These phase slips are induced …

Quantized rotation of atoms from photons with orbital angular momentum

MF Andersen, C Ryu, P Cladé, V Natarajan, A Vaziri… - Physical review …, 2006 - APS
We demonstrate the coherent transfer of the orbital angular momentum of a photon to an
atom in quantized units of ℏ, using a 2-photon stimulated Raman process with Laguerre …

Spontaneous coherence in a cold exciton gas

AA High, JR Leonard, AT Hammack, MM Fogler… - Nature, 2012 - nature.com
If bosonic particles are cooled down below the temperature of quantum degeneracy, they
can spontaneously form a coherent state in which individual matter waves synchronize and …

Observation of vortex dipoles in an oblate Bose-Einstein condensate

TW Neely, EC Samson, AS Bradley, MJ Davis… - Physical review …, 2010 - APS
We report experimental observations and numerical simulations of the formation, dynamics,
and lifetimes of single and multiply charged quantized vortex dipoles in highly oblate dilute …
