The Collision of Two Black Holes
Peter Anninos, David Hobill, Edward Seidel +2
We study the head-on collision of two equal mass, nonrotating black holes. We consider a range of cases from holes surrounded by a common horizon to holes initially separated by ab…
Squeezed States for General Systems
Michael Martin Nieto, D. Rodney Truax
We propose a ladder-operator method for obtaining the squeezed states of general symmetry systems. It is a generalization of the annihilation-operator technique for obtaining the c…
Higher Spin BRS Cohomology of Supersymmetric Chiral Matter in D=4
J. A. Dixon, R. Minasian, J. Rahmfeld
We examine the BRS cohomology of chiral matter in , supersymmetry to determine a general form of composite superfield operators which can suffer from supersymmetry anoma…
BRS Cohomology of the Supertranslations in D=4
J. A. Dixon, R. Minasian
Supersymmetry transformations are a kind of square root of spacetime translations. The corresponding Lie superalgebra always contains the supertranslation operator $ δ= c^α σ^μ_{α\…
Supersymmetry and a Time-Dependent Landau System
V. Alan Kostelecký, V. I. Man'ko, Michael Martin Nieto +1
A general technique is outlined for investigating supersymmetry properties of a charged spin-$\half$ quantum particle in time-varying electromagnetic fields. The case of a time-var…
