Pointlike objects cause many of the divergences that afflict physical theories. For instance, the gravitational binding energy of a point particle in Newtonian mechanics is infinite. In generalâ€¦ (More)

Defining energy is a surprisingly difficult problem in general relativity. For instance, the energy density of the gravitational field of a planet at a particular point could be determined by aâ€¦ (More)

The electromagnetic radiation of rotating relativistic electron layers is studied numerically using particle-in-cell simulation. This system is general enough to be applied to problems involving theâ€¦ (More)

At the interaction point of a storage ring each beam is subject to perturbations due to the electromagnetic field of the counter-rotating beam. These perturbations lead to a limit of the achievableâ€¦ (More)

Evaluating a functional integral exactly over a subset of metrics that represent the quantum fluctuations of the horizon of a black hole, we obtain a Schroedinger equation in null coordinate time forâ€¦ (More)
