Topological instabilities in ac-driven bosonic systems
G. Engelhardt, M. Benito, G. Platero +1
Under non-equilibrium conditions, bosonic modes can become dynamically unstable with an exponentially growing occupation. On the other hand, topological band structures give rise t…
Quantum signatures of Chimera states
V. M. Bastidas, I. Omelchenko, A. Zakharova +2
Chimera states are complex spatiotemporal patterns in networks of identical oscillators, characterized by the coexistence of synchronized and desynchronized dynamics. Here we propo…
Quantum phase transitions in networks of Lipkin-Meshkov-Glick models
A. V. Sorokin, V. M. Bastidas, T. Brandes
We study the quantum critical behavior of networks consisting of Lipkin-Meshkov-Glick models with an anisotropic ferromagnetic coupling. We focus on the low-energy properties of th…
Transport as a sensitive indicator of quantum criticality
Gernot Schaller, Malte Vogl, Tobias Brandes
We consider bosonic transport through one-dimensional spin systems. Transport is induced by coupling the spin systems to bosonic reservoirs kept at different temperatures. In the l…
Floquet topological quantum phase transitions in the transverse Wen-plaquette model
V. M. Bastidas, C. Emary, G. Schaller +3
Our aim in this work is to study the nonequilibrium behavior of the topological quantum phase transition in the transverse Wen-plaquette model. We show that under the effect of a n…
AC-driven Quantum Phase Transition in the Lipkin-Meshkov-Glick Model
G. Engelhardt, V. M. Bastidas, C. Emary +1
We establish a set of nonequilibrium quantum phase transitions in the Lipkin-Meshkov-Glick model under monochromatic modulation of the inter-particle interaction. We show that the…
