From Thermalization to Multifractality: Spin-Spin Correlation in Disordered -Invariant 1D Heisenberg Spin Chains
Debasmita Giri, Julian Siegl, John Schliemann
We investigate spin correlations in one-dimensional -invariant Heisenberg chains with exchange disorder for spin lengths and . In the weak-disorder regime, the…

Tunable plasmon modes and topological transitions in single- and bilayer semi-Dirac materials
Debasmita Giri, John Schliemann, Rafael Molina +1
We investigate the plasmonic response of single- and bilayer semi-Dirac materials under the influence of a tunable parameter that governs topological transitions via Dirac cone…

Skyrmion stripes in twisted double bilayer graphene
Debasmita Giri, Dibya Kanti Mukherjee, H. A. Fertig +1
Two dimensional moiré systems have recently emerged as a platform in which the interplay between topology and strong correlations of electrons play out in non-trivial ways. Among t…
