Drude weight increase by orbital and repulsive interactions in fermionic ladders
Andreas Haller, Matteo Rizzi, Michele Filippone
In strictly one-dimensional systems, repulsive interactions tend to reduce particle mobility on a lattice. Therefore, the Drude weight, controlling the divergence at zero-frequency…
Nucleation of ergodicity by a single mobile impurity in supercooled insulators
Ulrich Krause, Théo Pellegrin, Piet W. Brouwer +2
We consider a disordered Hubbard model, and show that, at sufficiently weak disorder, a single spin-down mobile impurity can thermalize an extensive initially localized system of s…
Multi-frequency Shubnikov-de Haas oscillations in topological semimetal PtHgSe
Diego Mauro, Hugo Henck, Marco Gibertini +4
Monolayer jacutingaite (PtHgSe) has been recently identified as a candidate quantum spin Hall system with a 0.5 eV band gap, but no transport measurements have been perform…
Direct measurement of non-local interactions in the many-body localized phase
B. Chiaro, C. Neill, A. Bohrdt +58
The interplay of interactions and strong disorder can lead to an exotic quantum many-body localized (MBL) phase. Beyond the absence of transport, the MBL phase has distinctive sign…
Vanishing Hall Response of Charged Fermions in a Transverse Magnetic Field
Michele Filippone, Charles-Edouard Bardyn, Sebastian Greschner +1
We study the Hall response of quasi-two-dimensional lattice systems of charged fermions under a weak transverse magnetic field, in the ballistic coherent limit. We identify a setup…
