An Atom Laser is not monochromatic
S. Choi, D. Stromberg, B. Sundaram
We study both numerically and analytically the possibility of using an adiabatic passage control method to construct a Mach-Zehnder interferometer (MZI) for Bose-Einstein condensat…
A nonlinear Ramsey interferometer operating beyond the Heisenberg limit
S. Choi, B. Sundaram
We show that a dynamically evolving two-mode Bose-Einstein condensate (TBEC) with an adiabatic, time-varying Raman coupling maps exactly onto a nonlinear Ramsey interferometer that…
Dynamics of vortex matter in rotating two-species Bose-Einstein condensates
S. J. Woo, S. Choi, L. O. Baksmaty +1
In a rotating two-component Bose-Einstein condensate (BEC), the traditional triangular vortex lattice can be replaced by a rectangular vortex lattice or even a structure characteri…
Quantum squeezing and entanglement in a two-mode Bose-Einstein condensate with time-dependent Josephson-like coupling
S. Choi, N. P. Bigelow
Dynamical evolution of quantum mechanical squeezing and entanglement in a two-mode Bose-Einstein condensate (TBEC) with an adiabatic, time-varying Raman coupling is studied by find…
Controlling quasiparticle excitations in a trapped Bose-Einstein condensate
S. J. Woo, S. Choi, N. P. Bigelow
We describe an approach to quantum control of the quasiparticle excitations in a trapped Bose-Einstein condensate based on adiabatic and diabatic changes in the trap anisotropy. We…
