Abstract

By the unitary transformation method,the instantaneous energy eigenstates of the L-S coupled systetn in a time-dependent magnetic field,hence the Berry phases,are calculated.

Time-dependent Landau system and non-adiabatic Berry phase in two dimensions

Jing Hui, Jiansheng Wu

By applying the time-independent unitary transformation, the time-dependent Landau system is transformed into a product of a time-independent Landau system's Hamiltonian and a factor only depending on time, which can be solved exactly. Both the invariant operator and the eigenstate are obtained. In the periodical time-dependent case, the non-adiabatic Berry's phase is also presented.

Berry Phase of Composite System Induced by Time-Dependent Interaction

Linguang Yang, Bin Shao, Zou Jian

The Berry phase in a composite system induced by the time-dependent interaction is discussed. We choose two coupled spin-1/2 systems as the composite system: one of the subsystems is subjected to a static magnetic field, and the coupling parameters between two spins are controllable in time. We show that the time-dependent interaction can induce the Berry phase in a similar way as that a spin-1/2 system (qubit) is driven by an effective time-dependent magnetic field. Furthermore, using two consecutive cycles with opposite directions of both the static magnetic field as well as opposite signs of the coupling parameters, a nontrivial two-qubit unitary transformation purely based on Berry phases can be constructed.

Berry's phase and wavefunctions for time-dependent Hamilton systems

P. G. L. Leach

An alternative derivation of Berry's phase (1985) to that given by Morales (1988) is given for non-autonomous Hamiltonian systems which admit an energy-like first integral. The generality of the problems treated is greater.
