Nonadiabatic Geometric Phase in Composite Systems and Its Subsystem

Xin Li

We point out that the time-dependent gauge transformation technique may be effective in investigating the nonadiabatic geometric phase of a subsystem in a composite system. As an example, we consider two uniaxially coupled spin —1/2 particles with one of particles driven by rotating magnetic Geld. The influences of coupling and precession frequency of the magnetic Geld on geometric phase are also discussed in detail.

Effect of intersubsystem couplings on the evolution of composite systems

X. X. Yi, H. T. Cui, Y.H. Lin +1 more

The effect of intersubsystem coupling on the adiabaticity of composite systems and that of its subsystems is investigated. Similar to the adiabatic evolution defined for pure states, nontransitional evolution for mixed states is introduced; conditions for the nontransitional evolution are derived and discussed. An example that describes two coupled qubits is presented to detail the general presentation. The effects due to nonadiabatic evolution on the geometric phase are also presented and discussed.

Berry phase and quantum entanglement in a nonreciprocal composite system

Xin Wang, H. D. Liu, X. X. Yi

In this work, we study the geometric phases and quantum entanglement of a composite system consisting of two interacting spin-1/2 particles in the presence of an external magnetic field. The conditions for real and complex eigenvalues are derived and discussed. Based on the non-Hermitian Berry phase, we propose the geometric phase of projective quantum states, discuss their relationship, and analyze their geometric properties. We expound on how the geometric phase of projective quantum states is contingent upon the coupling strength and the nonreciprocity between two subsystems, illustrating the connection between the geometric phase of the composite system and the geometric phases of its subsystems. By studying the quantum entanglement of the subsystems, the role of the correlation between the subsystem and the nonreciprocity is discussed. The results show that the quantum entanglement is influenced and determined by the nonreciprocity of the coupling. These schemes can provide a way to manipulate the nonreciprocal correlation between the subsystems to control the non-Hermiticity, geometric phase, and entanglement of the subsystems.
