The physics of optical vortices, also known as twisted light, is now a well-established and a
growing branch of optical physics with a number of important applications and significant …

Experiments at the interface of quantum optics and chemistry have revealed that strong
coupling between light and matter can substantially modify the chemical and physical …

In the interaction of molecules with light endowed with orbital angular momentum, an
exchange of orbital angular momentum in an electric dipole transition occurs only between …

It is well established that the interaction of light with matter generally imparts mechanical
forces and associated torques. Where laser light is involved, such effects can be deployed …

We show that a two-level atom moving in a Laguerre-Gaussian beam is subject to a light-
induced torque, T, about the beam axis which is directly proportional to l, the orbital angular …

Within the frame of macroscopic QED in linear, causal media, we study the radiation force of
Casimir-Polder type acting on an atom which is positioned near dispersing and absorbing …

We show that an atom moving in a light beam with orbital angular momentum experiences
an azimuthal shift in the resonant frequency in addition to the usual axial Doppler and recoil …

We derive a Hamiltonian for the external and internal dynamics of an electromagnetically
bound, charged two-particle system in external electromagnetic and gravitational fields …

We show how a simple calculation leads to the surprising result that an excited two-level
atom moving through a vacuum sees a tiny friction force of first order in v/c. At first sight this …

The usual multipolar Hamiltonian for atom-light interaction features a nonrelativistic moving
atom interacting with electromagnetic fields which inherently follow Lorentzian symmetry …
