Timelike self-similar spherically symmetric perfect-fluid models
Martin Goliath, Ulf S Nilsson, Claes Uggla
Einstein's field equations for timelike self-similar spherically symmetric perfect-fluid models are investigated. The field equations are rewritten as a first-order system of auton…

Spatially self-similar spherically symmetric perfect-fluid models
Martin Goliath, Ulf S Nilsson, Claes Uggla
Einstein's field equations for spatially self-similar spherically symmetric perfect-fluid models are investigated. The field equations are rewritten as a first-order system of auto…

A Field Theory for Partially Polarized Quantum Hall States
T. H. Hansson, A. Karlhede, J. M. Leinaas +1
We propose a new effective field theory for partially polarized quantum Hall states. The density and polarization for the mean field ground states are determined by couplings to tw…
