Critical Temperature Curve in BEC-BCS Crossover
Strong relevant regime condensation two-component system fermion monte carlo method function
2014/12/19
The strongly correlated regime of the crossover from Bardeen-Cooper-Schrieffer pairing to Bose-Einstein condensation can be realized by diluting a system of two-component fermions with a short-range a...
BCS-BEC crossover in spatially modulated fermionic condensates
BCS-BEC spatially modulated fermionic condensates
2011/7/20
Several novel multi-component fermionic condensates show universal behavior under imbalance in the number of fermionic species.
Population imbalance and pairing in the BCS-BEC crossover of three-component ultracold fermions
Population imbalance three-component ultracold fermions
2010/11/17
We investigate the phase diagram and the BCS-BEC crossover of a homogeneous three-component
ultracold Fermi gas with a U(3) invariant attractive interaction. We show that the system at
sufficiently ...

BCS-BEC crossover two-dimensional Fermi gas
2010/11/23
We investigate the crossover from Bardeen-Cooper-Schrieffer (BCS) superfluidity to Bose-Einstein condensation (BEC) in a two-dimensional Fermi gas at T = 0 using the fixed-node diffusion Monte Carlo m...
Emergent gravitational dynamics from multi-BEC hydrodynamics?
Emergent gravitational dynamics multi-BEC hydrodynamics
2010/12/20
In this paper, we examine the possibility to implement some form of emergent Newtonian gravity
in a generic multi-component Bose–Einstein condensate. Parallely to what happens for the emer-
gence of...
Revivals in the attractive BEC in a double-well potential and their decoherence
Revivals attractive BEC double-well potential their decoherence
2010/11/11
We study the dynamics of ultracold attractive atoms in a weakly linked two potential wells. We consider an unbalanced initial state and monitor dynamics of the population difference between the two we...
Physicists in Germany and France have coupled a Bose–Einstein condensate (BEC) of ultracold atoms to the vibrations of a mechanical oscillator for the first time. Although the oscillator is relatively...
近日，由中科院物理研究所王如泉副研究员带领的实验小组成功实现了87Rb的玻色-爱因斯坦凝聚（BEC）。这是继中科院上海光机所、北京大学、中科院武汉物理数学所和山西大学之后的国内第五台BEC实验装置。
物理所的设计具有以下几个独到之处：第一，没有采用传统的双磁光阱结构，系统只有一套磁光阱和一个真空腔。这种设计省掉了双磁光阱之间的推送光束，提高了搭建光晶格的光学自由度，便于搭建二维光晶格，而传统的双...
2010年2月9日，由王如泉副研究员带领的实验小组在中国科学院物理研究所/北京凝聚态物理国家实验室（筹）成功实现了87Rb的玻色-爱因斯坦凝聚（BEC）。这是继中科院上海光机所，北京大学，中科院武汉物理数学所和山西大学之后的国内第五台BEC实验装置。
Physicists in the US have become the first to use laser light to make neutral, ultracold atoms behave like charged particles in a magnetic field – even though the atoms have no charge. The set-up coul...
Quantum and Classical Dynamics of a BEC in a Large-Period Optical Lattice
Quantum and Classical Dynamics BEC Large-Period Optical Lattice
2010/4/8
We experimentally investigate diffraction of a Rb-87 Bose-Einstein condensate from a 1D optical lattice. We use a range of lattice periods and timescales, including those beyond the Raman-Nath limit. ...
