Imaging signatures of the local density of states in an electronic cavity
Carolin Gold, Beat A. Bräm, Michael S. Ferguson +9
We use Scanning Gate Microscopy to study electron transport through an open, gate-defined resonator in a Ga(Al)As heterostructure. Raster-scanning the voltage-biased metallic tip a…
Open quantum systems beyond Fermi's golden rule: Diagrammatic expansion of the steady-state time-convolutionless master equation
Michael Sven Ferguson, Oded Zilberberg, Gianni Blatter
Steady-state observables, such as occupation numbers and currents, are crucial experimental signatures in open quantum systems. The time-convolutionless (TCL) master equation, whic…
Quantum measurement induces a many-body transition
Michael S. Ferguson, Leon C. Camenzind, Clemens Müller +5
The current revolution in quantum technologies relies on the ability to isolate, coherently control, and measure the state of quantum systems. The act of measurement in quantum mec…
Tunneling into a finite Luttinger liquid coupled to noisy capacitive leads
Antonio Štrkalj, Michael S. Ferguson, Tobias M. R. Wolf +2
Tunneling spectroscopy of one-dimensional interacting wires can be profoundly sensitive to the boundary conditions of the wire. Here, we analyze the tunneling spectroscopy of a wir…
Long-range spin-coherence in a strongly-coupled all electronic dot-cavity system
Michael Sven Ferguson, David Oehri, Clemens Rössler +4
We present a theoretical analysis of spin-coherent electronic transport across a mesoscopic dot-cavity system. Such spin-coherent transport has been recently demonstrated in an exp…
