From Thermalization to Multifractality: Spin-Spin Correlation in Disordered $S U (2)$ -Invariant 1D Heisenberg Spin Chains

Debasmita Giri, Julian Siegl, John Schliemann

We investigate spin correlations in one-dimensional $S U (2)$ -invariant Heisenberg chains with exchange disorder for spin lengths $S = 1/2$ and $S = 1$ . 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 $I^´$ that governs topological transitions via Dirac con…
