Constraining Vacuum Energy

Eric Linton with Lawrence KraussConstraining Vacuum EnergyDistance measurements to Type Ia supernovae (SNe Ia) suggest that the expansion rate of the universe is increasing with time, contrary to previous beliefs about the evolution of the universe. One mechanism that could account for this acceleration is vacuum energy, also referred...

Cosmology with Vacuum Bubbles

David Olson with Glenn StarkmanCosmology with Vacuum BubblesRecently, there has been much excitement in the cosmology community over the results coming from surveys of Type Ia supernovae. These surveys seem to indicate that the rate of expansion of the universe (as measured by the relationship between the redshifts of...

Singularities in General Relativity

John Chunko with Tanmay VachaspatiSingularities in General RelativityThe determination of the presence of singularities in a general spacetime can be a very difficult task, especially since many apparent singularities can be removed by an appropriate coordinate transformation on the spacetime. One is therefore led to the construction of a...

Experimental Approach to Magnetic Field Confinement in a Dual-strip System

Jeff Kolthammer with Robert BrownExperimental Approach to Magnetic Field Confinement in a Dual-strip System There has appeared in literature a theoretical derivation of current conditions that lead to excellent magnetic-field confinement, called supershielding, in open-shield systems. A system consisting of two parallel, flat strips is used for illustration. We propose...
