The spinorial representation of polarized light and Berry phase
The spinorial representation polarized light Berry phase
2011/8/3
Abstract: From relativistic point of view it has been shown here that a polarized photon can be visualized to give an equivalent spinorial description when the two-component spinor is the eigenvector ...
Non-Abelian statistics as a Berry phase in exactly solvable models
Non-Abelian statistics Berry phase solvable models
2010/4/13
We demonstrate how to directly study non-Abelian statistics for a wide class of exactly solvable many-body quantum systems. By employing exact eigenstates to simulate the adiabatic transport of a mode...
Berry Phase and Fidelity in the Dicke model with $A^{2}$ term
Berry Phase Fidelity Dicke model with $A^{2}$ term
2010/4/8
The instability, so-called the quantum-phase-like transition, in the Dicke model with a rotating-wave approximation for finite $N$ atoms is investigated in terms of the Berry phase and the fidelity. I...
