Exploring bosonic bound states with parallel reaction coordinates
Guan-Yu Lai, Friedemann Queißer, Gernot Schaller
Bound states are dissipation-resilient states that may emerge when quantum systems are strongly coupled to reservoirs with band gaps. We analyze an exactly solvable bosonic model f…

Continuous Dimer Angles on the Silicon Surface: Critical Properties and the Kibble-Zurek Mechanism
Andreas Weitzel, Gernot Schaller, Friedemann Queisser +1
Langevin dynamics simulations are used to analyze the static and dynamic properties of an {XY} model adapted to dimers forming on Si(001) surfaces. The numerics utilise high-perfor…
