How quantum is quantum geometry?

Ady Stern, Felix von Oppen

The quantum geometric tensor - the Berry curvature together with the quantum metric - now underlies a long list of observables, from the anomalous Hall effect to the superfluid wei…

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…

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…

Robustness of real-space topology in moiré systems

Kryštof Kolář, Kang Yang, Felix von Oppen +1

The appearance of fractional Chern insulators in moiré systems can be rationalized by the presence of a fictitious magnetic field associated with the spatial texture of layer-resol…

Subharmonic spin correlations and spectral pairing in Floquet time crystals

Alexander-Georg Penner, Harald Schmid, Leonid I. Glazman +1

Floquet time crystals are characterized by subharmonic behavior of temporal correlation functions. Studying the paradigmatic time crystal based on the disordered Floquet quantum Is…

Self-similar phase diagram of the Fibonacci-driven quantum Ising model

Harald Schmid, Yang Peng, Gil Refael +1

We study a stroboscopic quantum Ising model with Fibonacci dynamics. Focusing on boundary spin correlation functions in long but finite chains, our simulations as well as analytica…
