Hidden Symmetries for Ellipsoid-Solitonic Deformations of Kerr-Sen Black Holes and Quantum Anomalies
Hidden symmetries in general relativity gravitational anomalies nonholonomic deformations
2011/6/6
Abstract: We prove the existence of hidden symmetries in the general relativity theory defined by exact solutions with generic off-diagonal metrics, nonholonomic (non-integrable) constraints, and defo...
Axial Symmetry, Anti-BRST Invariance and Modified Anomalies
Axial Symmetry Anti-BRST Invariance Modified Anomalies
2010/11/30
It is shown that anti-BRST symmetries are quantized counterparts of local axial symmetries in gauge theories. An extended form of descent equations is worked out which yields a set of modified consist...
Commensurability effects in one-dimensional Anderson localization: anomalies in eigenfunction statistics
Commensurability effects eigenfunction statistics
2010/11/1
The one-dimensional (1d) Anderson model (AM), i.e. a tight-binding chain with uncorrelated Gaussian disorder in the on-site energies, has statistical anomalies at any rational point f = 2a E , where ...
Finding structural anomalies in graphs by means of quantum walks
structural anomalies in graphs quantum walks
2010/9/1
We explore the possibility of using quantum walks on graphs to find structural anomalies, such as extra edges or loops, on a graph. We focus our attention on star graphs, whose edges are like spokes c...
