Dynamical self-dual criticality in Fibonacci-monitored quantum Ising chains
Finn Eckstein, Harald Schmid, Quinten Preiss +3
For the quantum phase transition in the transverse-field Ising chain, Kramers-Wannier duality not only protects its critical properties but also pinpoints the location of the phase…
Lifetime and spectral function of topological heavy fermions
Nemin Wei, Felix von Oppen, Leonid I. Glazman
Twisted bilayer graphene provides a paradigmatic platform for exploring the interplay between electronic topology and strong correlations. Within the topological heavy fermion mode…
Active quantum matter from monitored pure-state dynamics
Jacob F. Steiner, Felix von Oppen, Reinhold Egger
Quantum many-body systems coupled to out-of-equilibrium reservoirs can behave as active matter and exhibit signs of flocking. However, the resulting steady states are highly mixed…
Floquet product mode and eigenphase order
Felix Möckel, Harald Schmid, Felix von Oppen
We study the robustness of the Floquet quantum Ising model against integrability-breaking perturbations, focusing on the phase hosting both Majorana zero and modes. A recent w…
Tunneling signatures of interband coherence in dilute exciton condensates
KryÅ¡tof KoláÅ, Felix von Oppen
We theoretically investigate signatures of exciton condensation and the underlying interband coherence in scanning tunneling microscopy. We consider both monolayer and bilayer cond…
Superextensive charging speeds in a correlated quantum charger
Harald Schmid, Felix von Oppen, Gil Refael +1
We define a quantum charger as an interacting quantum system that transfers energy between two drives. The key figure of merit characterizing a charger is its charging power. Remar…
