Space-Time Foam and Cosmic-Ray Interactions
Marcin M. Jankiewicz, Roman V. Buniy, Thomas W. Kephart +1
It has been proposed that propagation of cosmic rays at extreme-energy may be sensitive to Lorentz-violating metric fluctuations (``foam''). We investigate the changes in interacti…
The eccentric universe
Arjun Berera, Roman V. Buniy, Thomas W. Kephart
For a universe containing cosmological constant together with uniform arrangements of magnetic fields, strings, or domain walls, exact solutions to the Einstein equations are shown…
On the existence of finite-energy lumps in classic field theories
Roman V. Buniy, Thomas W. Kephart
We show how the existence of non-trivial finite-energy time-dependent classical lumps is restricted by a generalized virial theorem. For simple model Lagrangians, bounds on energie…
