测量诱导量子扩散

Measurement-induced quantum diffusion

P. Facchi, S. Pascazio, A. Scardicchio

摘要:

研究了被踢量子系统在多次动量测量下的动力学行为。即使当经典对应物的动力学不是混沌时,也可以获得扩散行为。扩散系数显式计算的一大类哈密顿和经典的情况下相比。

英文摘要:

The dynamics of a kicked quantum system undergoing repeated measurements of momentum is investigated. A diffusive behavior is obtained even when the dynamics of the classical counterpart is not chaotic. The diffusion coefficient is explicitly computed for a large class of Hamiltonians and compared to the classical case.
