Spatial Compactification and Decay-Rate Behaviour
The transition from instanton-dominated quantum tunneling regime to sphaleron-dominated classical crossover regime is explored in (1+1)dimensional scalar field theory when spatial coordinate is compactified. It is shown that the type of sphaleron transition is critically dependent on the circumference of the spatial coordinate.
متن کاملEffect of Compactified Spatial Coordinate in Decay-Rate Phase Transition
The pahse transition from instanton-dominated quantum tunneling regime to sphaleron-dominated classical crossover regime is explored in (1+1)dimensional scalar field theory when spatial coordinate is compactified. It is shown that the type of sphaleron transition is critically dependent on the circumference of the spatial coordinate. Based on our main result we conjecture the type of winding nu...
متن کاملLong Lived Large Type II Strings: decay within compactification
Motivated also by recent revival of interest about metastable string states (as cosmic strings or in accelerator physics), we study the decay, in presence of dimensional compactification, of a particular superstring state, which was proven to be remarkably long-lived in the flat uncompactified scenario. We compute the decay rate by an exact numerical evaluation of the imaginary part of the one-...
متن کاملLarge-scale Curvature Perturbations with Spatial and Time Variations of the Inflaton Decay Rate
We present a gauge-invariant formalism to study the evolution of the curvature and entropy perturbations in the case in which spatial and time variations of the inflaton decay rate into ordinary matter are present. During the reheating stage after inflation curvature perturbations can vary with time on super-horizon scales sourced by a a gauge-invariant inflaton decay rate perturbation. We show...
متن کاملSpatial Behaviour and Linguistic Representation
Local and global reference frames in survey knowledge acquired from navigation and maps Tobias Meilinger Max Planck Institute Tübingen, Germany It has been a long standing question in spatial navigation research whether navigators represent their environment within a single reference frame (i.e. coordinate system) or within multiple local interconnected representations. Most results suggest tha...
