Weyl superconductors

open access: yes, 2017
We study the physics of the superconducting variant of Weyl semimetals, which may be realized in multilayer structures comprising topological insulators and superconductors. We show how superconductivity can split each Weyl node into two.

Type-II Weyl Semimetals

open access: yes, 2015
Fermions in nature come in several types: Dirac, Majorana and Weyl are theoretically thought to form a complete list. Even though Majorana and Weyl fermions have for decades remained experimentally elusive, condensed matter has recently emerged as ...

A Tree Soft Set Framework for Evaluating Teaching Quality in University Physics Programs: Enhancing Precision and Decision-Making [PDF]

open access: yesNeutrosophic Sets and Systems
Education in physics is at a crossroads. Numerous nations have middling or worse levels of scientific literacy, according to international research, and their students are viewed as being ill-equipped to handle the challenges going forward.

Spin and pseudospin symmetries of the Dirac equation with confining central potentials

open access: yes, 2013
We derive the node structure of the radial functions which are solutions of the Dirac equation with scalar $S$ and vector $V$ confining central potentials, in the conditions of exact spin or pseudospin symmetry, i.e., when one has $V=\pm S+C$, where $C ...

CaTe: a new topological node-line and Dirac semimetal

open access: yesnpj Quantum Materials, 2017
Topological physics: a predicted node-line semimetal CaTe Topological insulators are materials with non-trivial topological order that are insulating in their bulk but conductive on their surface.

Energetics and Dipole Moment of Transition Metal Monoxides by Quantum Monte Carlo

open access: yes, 2006
The transition metal-oxygen bond appears very prominently throughout chemistry and solid-state physics. Many materials, from biomolecules to ferroelectrics to the components of supernova remnants contain this bond in some form.
