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…
Signatures of folded branches in the scanning gate microscopy of ballistic electronic cavities
Keith R. Fratus, Camille Le Calonnec, Rodolfo A. Jalabert +2
We demonstrate the emergence of classical features in electronic quantum transport for the scanning gate microscopy response in a cavity defined by a quantum point contact and a mi…
Energy Stability of Branching in the Scanning Gate Response of Two-Dimensional Electron Gases with Smooth Disorder
Keith R. Fratus, Rodolfo A. Jalabert, Dietmar Weinmann
The branched pattern typically observed through the scanning gate microscopy (SGM) of two dimensional electron gases in the presence of weak, smooth disorder has recently been foun…
Does a Single Eigenstate of a Hamiltonian Encode the Critical Behaviour of its Finite-Temperature Phase Transition?
Keith R. Fratus, Syrian V. Truong
Recent work on the subject of isolated quantum thermalization has suggested that an individual energy eigenstate of a non-integrable quantum system may encode a significant amount…
