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...
Iterative Interplay between Aharonov-Bohm Deficit Angle and Berry Phase
abelian local non-pertubative nonabelian
2008/4/15
Geometric phases can be observed by interference as preferred
scattering directions in the Aharonov-Bohm (AB) effect or as Berry
phase shifts leading to precession on cyclic paths. Without
curvatur...
Irrational numbers can be assigned to physical entities based on
iterative processes of geometric objects. It is likely that
iterative round trips of vector signals include a geometric phase
