Cavity-induced quantum spin liquids
Alessio Chiocchetta, Dominik Kiese, Carl Philipp Zelle +2
Quantum spin liquids provide paradigmatic examples of highly entangled quantum states of matter. Frustration is the key mechanism to favor spin liquids over more conventional magne…
Epidemic growth and Griffiths effects on an emergent network of excited atoms
T. M. Wintermantel, M. Buchhold, S. Shevate +5
Whether it be physical, biological or social processes, complex systems exhibit dynamics that are exceedingly difficult to understand or predict from underlying principles. Here we…
Kibble-Zurek mechanism from different angles: The transverse XY model and subleading scalings
Björn Ladewig, Steven Mathey, Sebastian Diehl
The Kibble-Zurek mechanism describes the saturation of critical scaling upon dynamically approaching a phase transition. This is a consequence of the breaking of adiabaticity due t…
Symmetry classes of open fermionic quantum matter
Alexander Altland, Michael Fleischhauer, Sebastian Diehl
We present a full symmetry classification of fermion matter in and out of thermal equilibrium. Our approach starts from first principles, the ten different classes of linear and an…
Dynamic renormalization group theory for open Floquet systems
Steven Mathey, Sebastian Diehl
We develop a comprehensive Renormalization Group (RG) approach to criticality in open Floquet systems, where dissipation enables the system to reach a well-defined Floquet steady s…
Nonequilibrium quasistationary spin disordered state in the Kitaev-Heisenberg magnet -RuCl
R. B. Versteeg, A. Chiocchetta, F. Sekiguchi +9
Excitation by light pulses enables the manipulation of phases of quantum condensed matter. Here, we photoexcite high-energy holon-doublon pairs as a way to alter the magnetic free…
