Quotient symmetry protected topological phenomena
Topological phenomena are commonly studied in phases of matter which are separated
from a trivial phase by an unavoidable quantum phase transition. This can be overly …

Correlation driven metallic and half-metallic phases in a band insulator
We demonstrate a mechanism for realizing ferrimagnetic metal, antiferromagnetic half-metal,
and paramagnetic metal phases by tuning the onsite Coulomb repulsion U in a band …

[HTML][HTML] Interplay of electric field and disorder in Dirac liquid silicene
L Craco, SS Carara, S Leoni - The European Physical Journal B, 2021 - Springer
Layered materials with buckled structure offer a promising route to explore distinct phases of
quantum matter. Using GGA+ DMFT we reveal the complex interplay between perpendicular …

Unconventional superconductivity in a strongly correlated band-insulator without doping
A Chattopadhyay, A Garg - SciPost Physics Core, 2021 - scipost.org
We present a novel route for attaining unconventional superconductivity in a strongly
correlated system without doping. In a simple model of a correlated band insulator at half …
