Detecting and distinguishing topological defects in future data from the CMBPol satellite
distinguishing topological defects the CMBPol satellite
2011/1/11
The proposed CMBPol mission will be able to detect the imprint of topological defects on the cosmic microwave background (CMB) provided the contribution is sufficiently strong. We quantify the detecti...
Flat band in the core of topological defects: bulk-vortex correspondence in topological superfluids with Fermi points
Flat band topological superfluids Fermi points
2010/11/24
We consider the dimensional crossover in the topological matter, which involves the transformation of different types of topologically protected zeroes in the fermionic spectrum. In the considered cas...

A topological defect separating a pair of two-dimensional CFTs is a codimension one interface along which all components of the stress-energy tensor glue continuously. We study topological defects of ...
Heisenberg spin textures on a cylinder with topological defects
