Synchronized Aharonov-Bohm Motifs via Engineered Dissipation
Christopher W. Wächtler, Gloria Platero
The interplay between external gauge fields and lattice geometry can induce extreme localization dynamics through complete destructive interference. We show that combining this flu…
Nanoelectromechanical rotary current rectifier
Christopher W. Wächtler, Alan Celestino, Alexander Croy +1
Nanoelectromechanical systems (NEMS) are devices integrating electrical and mechanical functionality on the nanoscale. Because of individual electron tunneling, such systems can sh…
Coherently delocalized states in dipole interacting Rydberg ensembles: the role of internal degeneracies
Ghassan Abumwis, Christopher W. Wächtler, Matthew T. Eiles +1
We investigate the effect of degenerate atomic states on the exciton delocalization of dipole-dipole interacting Rydberg assemblies. Using a frozen gas and regular one-, two-, and…
Autonomous implementation of thermodynamic cycles at the nanoscale
Philipp Strasberg, Christopher W. Wächtler, Gernot Schaller
There are two paradigms to study nanoscale engines in stochastic and quantum thermodynamics. Autonomous models, which do not rely on any external time-dependence, and models that m…
Dissipative nonequilibrium synchronization of topological edge states via self-oscillation
C. W. Wächtler, V. M. Bastidas, G. Schaller +1
The interplay of synchronization and topological band structures with symmetry protected midgap states under the influence of driving and dissipation is largely unexplored. Here we…
Transport through a quantum critical system: A thermodynamically consistent approach
C. W. Wächtler, G. Schaller
Currents through quantum systems may probe non-analyticities in quantum-critical many-body ground states. For a large class of dissipative quantum critical systems we show that it…
Proposal of a realistic stochastic rotor engine based on electron shuttling
C. W. Wächtler, P. Strasberg, G. Schaller
We propose and analyse an autonomous engine, which combines ideas from electronic transport and self-oscillating heat engines. It is based on the electron-shuttling mechanism in co…
Stochastic thermodynamics of self-oscillations: the electron shuttle
C. W. Wächtler, P. Strasberg, S. H. L. Klapp +2
Self-oscillation is a phenomenon studied across many scientific disciplines, including the engineering of efficient heat engines and electric generators. We investigate the single…
