Imaging Electron Interferometer
B. J. LeRoy, A. C. Bleszynski, K. E. Aidala +6
An imaging interferometer was created in a two-dimensional electron gas by reflecting electron waves emitted from a quantum point contact (QPC) with a circular mirror. Images of el…
Thermal Electron Wavepacket Interferometry: Derivation and New Results
E. J. Heller, K. E. Aidala, B. J. LeRoy +5
A novel formal equivalence between thermal averages of coherent properties (e.g. conductance), and time averages of a single wavepacket arises for Fermi gasses and certain geometri…
Fidelity Decay for Phase Space Displacements
Diego V. Bevilaqua, Eric J. Heller
In this letter we analyse the behavior of fidelity decay under a very specific kind of perturbation: phase space displacements. Under these perturbations, systems will decay follow…
Imaging Coherent Electron Flow
B. J. LeRoy, A. C. Bleszynski, M. A. Topinka +5
Images of electron flow through a two-dimensional electron gas from a quantum point contact (QPC) can be obtained at liquid He temperatures using scanning probe microscopy (SPM). A…
Quantum Multiple Scattering: Eigenmode Expansion and Its Applications to Proximity Resonance
Sheng Li, Eric J. Heller
We show that for a general system of N s-wave point scatterers, there are always N eigenmodes. These eigenmodes or eigenchannels play the same role as spherical harmonics for a sph…
Quantum Coherence Beyond the Thermal Length
S. E. J. Shaw, R. Fleischmann, E. J. Heller
Recent experiments have used scattering to map the flow of electrons in a two-dimensional electron gas. Among other things, the data from these experiments show perseverance of reg…
