驱动晶格中的相互作用-感应电流-反转
Interaction-induced current-reversals in driven lattices
摘要：
我们表明，长程相互作用可以导致，随着时间的推移，连续的逆转的定向电流的稀释合奏的粒子在驱动晶格。这些电流反转是基于一个一般的机制，导致相互作用引起的积累的粒子在规则区域的基础单粒子相空间和同步的单粒子运动，以及提高效率的哈密顿棘轮。
英文摘要：
We demonstrate that long-range interactions can cause, as time evolves, consecutive reversals of directed currents for dilute ensembles of particles in driven lattices. These current-reversals are based on a general mechanism which leads to an interaction-induced accumulation of particles in the regular regions of the underlying single-particle phase space and to a synchronized single-particle motion as well as an enhanced efficiency of Hamiltonian ratchets.
