Bell’s inequality and entanglement in qubits

open access: yesJournal of High Energy Physics, 2017
We propose an alternative evaluation of quantum entanglement by measuring the maximum violation of the Bell’s inequality without information of the reduced density matrix of a system. This proposal is demonstrated by bridging the maximum violation of the

Effects of spin symmetry breaking in topological insulators [PDF]

open access: yes, 2015
Topological insulators are one of the most thoroughly investigated systems in condensed matter physics over the last years. In these systems, a prominent role is inevitably taken by time-reversal symmetry, which leads to Kramers theorem and symmetry ...

Higher-order topological matter and fractional chiral states

open access: yesThe European Physical Journal Plus, 2022
We develop a chiral anomalous fermion hamiltonian proposal to study the higher order topological (HOT) phase with chiral symmetry $\mathcal{C}$ fractionalized like $\mathcal{C}_{x}\mathcal{C}_{y}\mathcal{C}_{z}$. First, we solve the $\mathcal{C}$-chiral symmetry constraint for eight band models and describe those induced by the partial $\mathcal{C}_{i}$

Interferometric schemes: a probe for topological edge states, a tool in weak measurements [PDF]

open access: yes, 2014
In the first part of this thesis we propose interferometric schemes to probe the properties of edge states of topological insulators and superconductors.

Self-stabilizing temperature driven crossover between topological and non-topological ordered phases in one-dimensional conductors [PDF]

open access: yes, 2015
We present a self-consistent analysis of the topological superconductivity arising from the interaction between self-ordered localized magnetic moments and electrons in one-dimensional conductors in contact with a superconductor.

Entanglement entropy, quantum fluctuations, and thermal entropy in topological phases

open access: yesJournal of High Energy Physics, 2019
Entanglement entropy in topologically ordered matter phases has been computed extensively using various methods. In this paper, we study the entanglement entropy of topological phases in two-spaces from a new perspective — the perspective of ...

Extended dynamical symmetries of Landau levels in higher dimensions

open access: yesJournal of High Energy Physics, 2020
Continuum models for time-reversal (TR) invariant topological insulators (Tis) in d ≥ 3 dimensions are provided by harmonic oscillators coupled to certain SO(d) gauge fields.

Dirac surface states and nature of superconductivity in noncentrosymmetric BiPd [PDF]

open access: yes, 2015
In non-magnetic bulk materials, inversion symmetry protects the spin degeneracy. If the bulk crystal structure lacks a centre of inversion, however, spin-orbit interactions lift the spin degeneracy, leading to a Rashba metal whose Fermi surfaces exhibit ...
