Topological crystalline superconductors in two dimensions.

Summary of "Topological crystalline superconductors in two dimensions."

We propose a general framework to classify the topological edge modes in two dimensional
 topological crystalline superconductors with time-reversal symmetry,
 which are protected by different crystalline symmetries. The realization of topological
 crystalline phases is investigated in the superconductors and a criterion for
 distinguishing topological phases in crystalline superconductor both with mirror and
 mirror-inversion symmetry is founded. In these topological phases, Majorana edge
 modes can be identified along the mirror invariant line, while topological edge modes
 in the AIII class exist along the mirror-inversion invariant line. Furthermore, for the
 time-reversal invariant superconductor when only the mirror-inversion symmetry is
 preserving, topological edge modes in the AIII class with nearly flat band emerge in
 the mirror-inversion parity subspace.

Medical and Biotech [MESH] Definitions

A set of statistical methods for analyzing the correlations among several variables in order to estimate the number of fundamental dimensions that underlie the observed data and to describe and measure those dimensions. It is used frequently in the development of scoring systems for rating scales and questionnaires.

The core of the crystalline lens, surrounded by the cortex.

The portion of the crystalline lens surrounding the nucleus and bound anteriorly by the epithelium and posteriorly by the capsule. It contains lens fibers and amorphous, intercellular substance.

The clear, watery fluid which fills the anterior and posterior chambers of the eye. It has a refractive index lower than the crystalline lens, which it surrounds, and is involved in the metabolism of the cornea and the crystalline lens. (Cline et al., Dictionary of Visual Science, 4th ed, p319)

Investigative techniques which measure the topological, geometric, and or geographic properties of the entities studied.
