The geometric and topological interpretation of Berry phase on a torus
Da-Bao Yang, Kun Meng, Yi-Zhi Wu +1
Illustration of the geometric and topological properties of Berry phase is often in an obscure and abstract language of fiber bundles. In this article, we demonstrate these propert…
Thermal effect on mixed state geometric phases for neutrino propagation in a magnetic field
Da-Bao Yang, Ji-Xuan Hou, Ku Meng
In astrophysical environments, neutrinos may propagate over a long distance in a magnetic field. In the presence of a rotating magentic field, the neutrino spin can flip from left-…
Geometric phases for two-mode squeezed state
Da-Bao Yang, Ji-Xuan Hou
Although the geometric phase for one-mode squeezed state had been studied in detail, the counterpart for two-mode squeezed state is vacant. It is be evaluated explicitly in this pa…
Berry phases for interacting spins in composite environments
Da-Bao Yang, Fu-Lin Zhang, Jing-Ling Chen
Due to the potential application in quantum information process, geometric phase of interacting system arouse many interests. Some physicists concentrate on the system in pure clas…
Geometric Phases for Coherent States
Da-Bao Yang, Jing-Ling Chen, Chunfeng Wu +1
We explore geometric phases of coherent states and some of their properties. A better and elegant expression of geometric phase for coherent state is derived. It is used to obtain…
Demonstrating Additional Law of Relativistic Velocities based on Squeezed Light
Da-Bao Yang, Yan Li, Fu-Lin Zhang +1
Special relativity is foundation of many branches of modern physics, of which theoretical results are far beyond our daily experience and hard to realized in kinematic experiments.…
