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 w…
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…
