Relativistic Quantum State, Geometric Phase and Dissipationless Spin current
Relativistic Quantum State Geometric Phase Dissipationless Spin current
2011/8/11
Abstract: Spin current of a Dirac particle is shown to be given by the geometric phase and in terms of the later, a closed form expression is obtained for the dissipationlessness of the spin current.
Geometric phase for nonlinear coherent and squeezed state
geometric phase nonlinear coherent squeezed state
2010/11/8
The non-unitary and non-cyclic geometric phase for two nonlinear coherent and one squeezed tates are formulated. Moreover, the nonlinear results are reduced to geometric phases of standard oherent and...

We derive an effective Hamiltonian for a quantum system constrained to a submanifold (the
constraint manifold) of configuration space (the ambient space) by an infinite restoring force. We pay specia...

Cosmological Adiabatic Geometric Phase of a Scalar Field in a Bianchi Spacetime
Cosmological Adiabatic Geometric Phase Scalar Field
2010/4/15
A two-component formulation of the Klein-Gordon equation is used to investigate the cyclic and noncyclic adiabatic geometric phases due to spatially homogeneous (Bianchi) cosmological models. It is sh...
