Topological Signatures for Population Admixture

2015
As populations with multilinear transmission (i.e., mixing of genetic material from two parents, say) evolve over generations, the genetic transmission lines constitute complicated networks. In contrast, unilinear transmission leads to simpler network structures (trees).

Optical signature of topological insulators

Physical Review B, 2009
The axion coupling in topological insulators couples electric polarization with magnetic field, and magnetization with electric field. As a result, the usual laws of electromagnetic wave propagation are modified. We report on the Fresnel formula for the reflection of electromagnetic wave at the interface of materials with different axion couplings. The

Signatures of Topological Superconductors

2015
Topological superconductors are particularly interesting in light of the active ongoing experimental efforts for realizing exotic physics such as Majorana zero modes. These systems have excitations with non-Abelian exchange statistics, which provides a path towards topological quantum information processing.

Experimental Signatures of Topological Insulators

2017
Energy bands in solids describe quantum states in periodic crystals. When a quantum state is wound around the Brillouin zone, it acquires a quantum phase. For a completely filled band, the global phase acquired in this winding is a topological property of the band. For 3D solid with timereversal symmetry, there are two topological classes corresponding

Topological Signatures for Classification

2016
In recent years the statistical analysis of topological signatures computable from a possibly high-dimensional point cloud has attracted increasing attention from a theoretical as well as applied point of view. In this work we briefly review the basic techniques and main inferential results available in the TDA (Topological Data Analysis) toolkit ...

Topological Signatures of Multiregional Dynamics

Multiregional dynamics, characterized by complex interactions among spatially distributed components, are fundamental to understanding intricate systems ranging from the human brain to global climate patterns and social networks. Traditional analytical methods often focus on pairwise correlations or static network structures, potentially overlooking ...
