Winding Strings in Singular Spacetimes
Marek Pawlowski, Wlodzimierz Piechocki, Michal Spalinski
Evolution of winding strings in spacetimes with cycles whose proper lengths depend on time is examined. It was established earlier that extended objects wrapping the shrinking dime…
Simple model of big-crunch/big-bang transition
Przemyslaw Malkiewicz, Wlodzimierz Piechocki
We present classical and quantum dynamics of a test particle in the compactified Milne space. Background spacetime includes one compact space dimension undergoing contraction to a…
On three quantization methods for particle on hyperboloid
Jean-Pierre Gazeau, Marc Lachieze-Rey, Wlodzimierz Piechocki
We compare the respective efficiencies of three quantization methods (group theoretical, coherent state and geometric) by quantizing the dynamics of a free massive particle in two-…
