Gravitational field of twisted Baby Skyrmion strings and loops
Gravitational field twisted Baby Skyrmion Einstein equations
2010/3/18
We consider the gravitational field of infinite straight and stationary twisted Baby Skyrmion cosmic string. Using the approximate solution of Einstein equations, it is shown that the internal phase r...
Polymer quantization of the free scalar field and its classical limit
free scalar field Polymer quantization classical limit
2010/3/18
Building on prior work, a generally covariant reformulation of free scalar field theory on the flat Lorentzian cylinder is quantized using Loop Quantum Gravity (LQG) type `polymer' representations. Th...
