Adiabatic Quantum Transport in a Spin Chain with a Moving Potential
Vinitha Balachandran, Jiangbin Gong
Many schemes to realize quantum state transfer in spin chains are not robust to random fluctuations in the spin-spin coupling strength. In efforts to achieve robust quantum state t…
Two-mode Bose-Einstein condensate in a high-frequency driving field that directly couples the two modes
Qi Zhang, Peter Hanggi, Jiangbin Gong
A two-mode Bose-Einstein condensate coupled by a high-frequency modulation field is found to display rich features. An effective stationary Hamiltonian approach reveals the emergen…
Proposal of a Cold-atom Realization of Quantum Maps with Hofstadter's Butterfly Spectrum
Jiao Wang, Jiangbin Gong
Quantum systems with Hofstadter's butterfly spectrum are of fundamental interest to many research areas. Based upon slight modifications of existing cold-atom experiments, a cold-a…
Controlling the Ratchet Effect for Cold Atoms
Anatole Kenfack, Jiangbin Gong, Arjendu K. Pattanayak
Low-order quantum resonances manifested by directed currents have been realized with cold atoms. Here we show that by increasing the strength of an experimentally achievable delta-…
Controlled Quantum State Transfer in a Spin Chain
Jiangbin Gong, Paul Brumer
Control of the transfer of quantum information encoded in quantum wavepackets moving along a spin chain is demonstrated. Specifically, based on a relationship with control in a par…
Dissipationless Directed Transport in Rocked Single-Band Quantum Dynamics
Jiangbin Gong, Dario Poletti, Peter Hanggi
Using matter waves that are trapped in a deep optical lattice, dissipationless directed transport is demonstrated to occur if the single-band quantum dynamics is periodically tilte…
