一类Hamilton算子的弱关联子和含时Aharonov-Bohm通量的Landau Hamilton算子的绝热定理

Propagators weakly associated to a family of Hamiltonians and the adiabatic theorem for the Landau Hamiltonian with a time-dependent Aharonov-Bohm flux

J. Asch, I. Hradecky, P. Stovicek

摘要:

研究了在恒定磁场作用下,在慢含时奇异通量管驱动下,量子粒子在平面内运动的动力学问题。已知的绝热结果不包括这些模型,因为哈密顿量具有时间依赖域。我们给出了传播子的意义,并证明了一个绝热定理。为此,我们引进和发展的传播弱相关的含时哈密顿量的新概念。

英文摘要:

We study the dynamics of a quantum particle moving in a plane under the influence of a constant magnetic field and driven by a slowly time-dependent singular flux tube through a puncture. The known adiabatic results do not cover these models as the Hamiltonian has time dependent domain. We give a meaning to the propagator and prove an adiabatic theorem. To this end we introduce and develop the new notion of a propagator weakly associated to a time-dependent Hamiltonian.
