Chiral Parafermions in Floquet Topological Order
Melissa Will, Harald Schmid, Jan Egger +3
Floquet topological order (FTO) extends topology beyond equilibrium, giving rise to phenomena, such as the dynamical transmutation of anyons. Here, we realize FTO in…
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…
Genuine quantum scars in Floquet chaotic many-body systems
Harald Schmid, Andrea Pizzi, Johannes Knolle
Unstable periodic orbits act as organizing structures for classical chaotic systems and underpin quantum scarring. Long known in single-particle systems, genuine quantum scars base…
Transcendental momentum quantization in semiconducting Rashba nanowires and zero energy states in their normal and superconducting phase
Nico Leumer, Harald Schmid, Milena Grifoni +1
We study finite system properties of the canonical low energy model for a semiconducting nanowire with Rashba spin-orbit coupling. The case of an isolated wire as well as of one pr…
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 wo…
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…
Odd-parity ground state in dilute Yu-Shiba-Rusinov dimers and chains
Lisa M. Rütten, Harald Schmid, Werner M. J. van Weerdenburg +3
Magnetic adatoms on superconductors induce Yu-Shiba-Rusinov (YSR) states, which are key to the design of low-dimensional correlated systems and topological superconductivity. Compe…
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…
Wave-function engineering on superconducting substrates: Chiral Yu-Shiba-Rusinov molecules
Lisa M. Rütten, Harald Schmid, Eva Liebhaber +6
Magnetic adatoms on superconductors give rise to Yu-Shiba-Rusinov (YSR) states that hold considerable interest for the design of topological superconductivity. Here, we show that Y…
Robust spectral pairing in the random-field Floquet quantum Ising model
Harald Schmid, Alexander-Georg Penner, Kang Yang +2
Motivated by an experiment on a superconducting quantum processor [Mi et al., Science 378, 785 (2022)], we study level pairings in the many-body spectrum of the random-field Floque…
