Decoherence of spatial superpositions along stationary worldlines
Clemens Jakubec, Aaron Bartleson, Peter W. Milonni +1
We analyze the decoherence of a particle's spatial superposition moving along a stationary worldline through the Minkowski vacuum. The particle is modeled via an internal degree of…
Effect of Self-Interaction on Feynman's Interpretation of the Lamb Shift
Peter W. Milonni, Paul R. Berman, Kanu Sinha
We derive Bethe's formula for the Lamb shift by extending Feynman's suggestion that the shift could be interpreted as the change, due to the presence of the atom, in electromagneti…
Decoherence and Brownian motion of a polarizable particle near a surface
Clemens Jakubec, Christopher Jarzynski, Kanu Sinha
We analyze the classical and quantized center-of-mass motion of a polarizable particle interacting with the fluctuations of the electromagnetic (EM) field in the presence of a medi…
Scalar QED Model for Polarizable Particles in Thermal Equilibrium or in Hyperbolic Motion in Vacuum
Kanu Sinha, Peter W. Milonni
We consider a scalar QED model for the frictional force and the momentum fluctuations of a polarizable particle in thermal equilibrium with radiation or in hyperbolic motion in a v…
