Fractional Angular Momentum and Quasi-Probability Densities for Angular Degrees of Freedom
Bo-Sture K. Skagerstam, Per K. Rekdal
In the present update work we consider properly defined two-parameter quasi-probability densities that, e.g., can be used as witness for quantum behaviour for a class of pure state…
On Quantum States for angular Position and Angular Momentum of Light
Bo-Sture K. Skagerstam, Per K. Rekdal
In the present paper we construct a properly defined quantum state expressed in terms of elliptic Jacobi theta functions for the self-adjoint observables angular position and t…
Quantum Field Theory with Classical Sources - Linearized Quantum Gravity
Bo-Sture K. Skagerstam, Karl-Erik Eriksson, Per K. Rekdal
In a previous work and in terms of an exact quantum-mechanical framework, -independent causal and retarded expectation values of the second-quantized electro-magnetic fields…
Causality in Quantum Field Theory with Classical Sources - Quantum Electrodynamics
Bo-Sture K. Skagerstam, Karl-Erik Eriksson, Per K. Rekdal
In an exact quantum-mechanical framework, we show that expectation values of the second-quantized electro-magnetic fields in the Coulomb gauge, and in the presence of classical sou…
Memory Effects in Spontaneous Emission Processes
Arne L. Grimsmo, Asle H. Vaskinn, Per K. Rekdal +1
We consider a quantum-mechanical analysis of spontaneous emission in terms of an effective two-level system with a vacuum decay rate and transition angular frequency . O…
On the Theory of Casimir-Polder Forces
Bo-Sture Skagerstam, Per Kristian Rekdal, Asle Heide Vaskinn
We consider the energy shift for an atom close to a non-magnetic body with a magnetic moment coupled to a quantized magnetic field. The corresponding repulsive Casimir-Polder force…
