For the experiment, a reasonable number of atoms at small initial momenta is of paramount importance, and we therefore use a Bose-Einstein condensate (BEC) of (F = 1) 87Rb at a temperature of 50 nK as the source of atoms.
Experimental observation of Loschmidt time reversal of a Quantum Chaotic System
We have used a total atom number of N = 100 corresponding to a square amplitude |α|2 = 50 for the two independent coherent states.
Tests of Bose-broken Symmetry in Atomic Bose-Einstein Condensates
The computational complexity of the MD lies in two factors : the number of particles N , and the time scale of the phenomenon under simulation. A typical example is the melting of a simple cubic solid with dimension 50 lattice constants which requires 125,000 atoms simulation.
Implementation of parallel algorithms for 2D vortex dynamics simulation in type-II superconductors
This phase gives rise to coherence and interference phenomena which, in a number of experiments with degenerate atomic gases, has been made visible in a macroscopic manner, e.g., in the experiments reported in Refs. [50,51,52,53,54].
