Berry Phase in Jaynes-cummings Model for a Tunneling Quantum-dot Molecule
摘要
Abstract
In order to provide advice on the control of the geometric phase of a quantum system,it explores the Berry phase in a tunneling double-quantum-dot molecule interacting with a quantized singlemode field by the full quantum theory.Effects of parameters,such as the mean photon number of the field,field-dot detuning,tunneling energy-level detuning,linear and nonlinear field-dot coupling,on the geometric phase were researched.The results show that in the region where anticrossing of the eigenenengy levels of the system occurs,the Berry phase can be efficiently controlled by adjusting the applied voltage exerted on the quantum-dot molecule.The conclusion may be applied in quantum computation.关键词
