RESEARCH DESCRIPTION

The focus of my research is on quantum field theory, which is the basis for our understanding of the fundamental forces of nature.  The most successful quantum field theory is quantum electrodynamics, which governs all of atomic physics, chemistry, biology, and condensed matter physics.  The key to its success is that the electromagnetic coupling constant, the charge of the electron, is very small in natural units, so weak-coupling expansions (perturbation theories) are practical.  The same is not true in the nuclear and subnuclear domain, where the couplings can be large.  Therefore, a large part of my career concentrated on exploring methods to transcend the limitations to weakly coupled theories.

 

My present work (going back 45 years!) largely concentrates on the Casimir effect, or more generally quantum vacuum energy phenomena.  This is also nonperturbative in that the background reflects nontrivial topological configurations of the underlying fields.  Currently being explored are quantum frictional forces, negative Casimir entropy, Casimir energies of inhomogeneous systems, repulsive Casimir forces, and local quantum effects (Casimir energy and force densities).  These ideas are being applied to cosmological and subnuclear systems, as well as to real-world phenomena, such as to the freezing of ice onto surfaces.  This work is being done in collaboration with a diverse group of scientists, of all ages and career stages,  spread around the world, linked through internet communication.
