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…
Photodriven germanium hole qubit
Bashab Dey, John Schliemann
Hole qubits in germanium quantum dots are promising candidates for coherent control and manipulation of the spin degree of freedom through electric dipole spin resonance. We theore…
Imperfect Many-Body Localization in Exchange-Disordered Isotropic Spin Chains
Julian Siegl, John Schliemann
We investigate many-body localization in isotropic Heisenberg spin chains with the local exchange parameters being subject to quenched disorder. Such systems incorporate a nonabeli…
Neutral magic-angle bilayer graphene: Condon instability and chiral resonances
T. Stauber, M. Wackerl, P. Wenk +4
We discuss the full optical response of twisted bilayer graphene at the neutrality point close to the magic angle within the continuum model (CM). Firstly, we identify three differ…
Topological transitions in two-dimensional Floquet superconductors
Paul Wenk, Milena Grifoni, John Schliemann
We demonstrate the occurrence of a topological phase transition induced by an effective magnetic field in a two-dimensional electron gas with spin-orbit coupling and in proximity t…
Many-Body Localization: Transitions in Spin Models
John Schliemann, Joao Vitor I. Costa, Paul Wenk +1
We study the transitions between ergodic and many-body localized phases in spin systems, subject to quenched disorder, including the Heisenberg chain and the central spin model. In…
