Melting of Discrete Vortices via Quantum Fluctuations
Chaohong Lee, Tristram J. Alexander, Yuri S. Kivshar
We consider nonlinear boson states with a nontrivial phase structure in the three-site Bose-Hubbard ring, {\em quantum discrete vortices} (or {\em q-vortices}), and study their "me…

Adiabatic Mach-Zehnder Interferometry on A Quantized Bose-Josephson Junction
Chaohong Lee
We propose a scheme to achieve a Mach-Zehnder interferometry using a quantized Bose-Josephson junction with negative charging energy. The quantum adiabatic evolution through a dyna…
