Abstract

The transport of ultracold atoms in a two-leg ladder under non-uniform artificial magnetic field is studied analytically and numerically. Introducing a non-uniform magnetic field as a magnetic barrier produces rich phenomena, similar to the transmission and the reflection of light beams propagating in a non-uniform media. The phase diagram describing atomic transmission and reflection at the magnetic barrier is given. Atomic transport can be effectively controlled by the magnetic field. Interestingly, when atoms transmit through the barrier, magnetic induced resistance and dynamical biased ladder state are observed, offering an efficient dynamical way for realizing the biased ladder phase. Our work provides an theoretical evidence for the coherent control of atomic matter waves in magnetized lattice systems and the design of novel atomic optical devices.

期刊介绍: Physics Letters A offers an exciting publication outlet for novel and frontier physics. It encourages the submission of new research on: condensed matter physics, theoretical physics, nonlinear science, statistical physics, mathematical and computational physics, general and cross-disciplinary physics (including foundations), atomic, molecular and cluster physics, plasma and fluid physics, optical physics, biological physics and nanoscience. No articles on High Energy and Nuclear Physics are published in Physics Letters A. The journal''s high standard and wide dissemination ensures a broad readership amongst the physics community. Rapid publication times and flexible length restrictions give Physics Letters A the edge over other journals in the field.
