Gravitational acceleration in a class of geometric sigma models
Milovan Vasilic
In this work, I examine spherically symmetric solutions in geometric sigma models with four scalar fields. This class of models turns out to be a subclass of the wider class of sca…
Spinning branes in Riemann-Cartan spacetime
Milovan Vasilic, Marko Vojinovic
We use the conservation law of the stress-energy and spin tensors to study the motion of massive brane-like objects in Riemann-Cartan geometry. The world-sheet equations and bounda…
Interaction of the Particle with the String in Pole-Dipole Approximation
Milovan Vasilic, Marko Vojinovic
Within the framework of generalized Papapetrou method, we derive the effective equations of motion for a string with two particles attached to its ends, along with appropriate boun…
String background fields and Riemann-Cartan geometry
Milovan Vasilic
We study classical dynamics of cylindrical membranes wrapped around the extra compact dimension of a -dimensional Riemann-Cartan spacetime. The world-sheet equations and bou…
Test membranes in Riemann-Cartan spacetimes
Milovan Vasilic, Marko Vojinovic
The dynamics of brane-like extended objects in spacetimes with torsion is derived from the conservation equations of stress-energy and spin tensors. Thus obtained world-sheet equat…
Zero-size objects in Riemann-Cartan spacetime
Milovan Vasilic, Marko Vojinovic
We use the conservation law of the stress-energy and spin tensors to study the motion of massive zero-size objects in Riemann-Cartan geometry. The resultant world line equations tu…
