Nonadiabatic production of spinor condensates with a QUIC trap
P. Zhang, Z. Xu, L. You
Motivated by the recent experimental observation of multi-component spinor condensates via a time-dependent quadrupole-Ioffe-configuration trap (QUIC trap), we provide a general fr…
Effective size of a trapped atomic Bose gas
Wenxian Zhang, Z. Xu, L. You
We investigate the temperature-dependent effective size of a trapped interacting atomic Bose gas within a mean field theory approximation. The sudden shrinking of the average lengt…
Dynamical instability and domain formation in a spin-1 Bose condensate
Wenxian Zhang, D. L. Zhou, M. -S. Chang +2
We interpret the recently observed spatial domain formation in spin-1 atomic condensates as a result of dynamical instability. Within the mean field theory, a homogeneous condensat…
Quantum information cannot be split into complementary parts
D. L. Zhou, B. Zeng, L. You
We prove a new impossibility for quantum information (the no-splitting theorem): an unknown quantum bit (qubit) cannot be split into two complementary qubits. This impossibility, t…
Coherent spin mixing dynamics in a spin-1 atomic condensate
Wenxian Zhang, D. L. Zhou, M. -S. Chang +2
We study the coherent off-equilibrium spin mixing inside an atomic condensate. Using mean field theory and adopting the single spatial mode approximation (SMA), the condensate spin…
Entanglement and spin squeezing properties for three bosons in two modes
B. Zeng, D. L. Zhou, Z. Xu +1
We discuss the canonical form for a pure state of three identical bosons in two modes, and classify its entanglement correlation into two types, the analogous GHZ and the W types a…
