Time-resolved Coulomb collision of single electrons
J. D. Fletcher, W. Park, S. Ryu +7
Precise control over interactions between ballistic electrons will enable us to exploit Coulomb interactions in novel ways, to develop high-speed sensing, to reach a non-linear reg…
Nonlinear spectra of spinons and holons in short GaAs quantum wires
M. Moreno, C. J. B. Ford, Y. Jin +6
One-dimensional electronic fluids are peculiar conducting systems, where the fundamental role of interactions leads to exotic, emergent phenomena, such as spin-charge (spinon-holon…
Hierarchy of modes in an interacting system
O. Tsyplyatyev, A. J. Schofield, Y. Jin +7
Studying interacting fermions in 1D at high energy, we find a hierarchy in the spectral weights of the excitations theoretically and we observe evidence for second-level excitation…
Density-dependent thermopower oscillations in mesoscopic two-dimensional electron gases
Vijay Narayan, Eugene Kogan, Chris Ford +6
We present thermopower and resistance measurements on GaAs-based mesoscopic two-dimensional electron gases (2DEGs) as functions of the electron density . At high …
In-plane emission of indistinguishable photons generated by an integrated quantum emitter
Sokratis Kalliakos, Yarden Brody, Andre Schwagmann +9
We demonstrate the emission of indistinguishable photons along a semiconductor chip originating from carrier recombination in an InAs quantum dot. The emitter is integrated in the…
On-chip generation and guiding of quantum light from a site-controlled quantum dot
Ayesha Jamil, Joanna Skiba-Szymanska, Sokratis Kalliakos +9
We demonstrate the emission and routing of single photons along a semiconductor chip originating from carrier recombination in an actively positioned InAs quantum dot. Device scale…
A non-invasive electron thermometer based on charge sensing of a quantum dot
A. Mavalankar, S. J. Chorley, J. Griffiths +4
We present a thermometry scheme to extract the temperature of a 2DEG by monitoring the charge occupation of a weakly tunnel-coupled 'thermometer' quantum dot using a quantum point…
Unconventional Metallicity and Giant Thermopower in a Strongly Interacting Two Dimensional Electron System
Vijay Narayan, Srijit Goswami, Michael Pepper +6
We present thermal and electrical transport measurements of low-density (10 m), mesoscopic two-dimensional electron systems (2DESs) in GaAs/AlGaAs heterostructures at…
On-chip single photon emission from an integrated semiconductor quantum dot into a photonic crystal waveguide
Andre Schwagmann, Sokratis Kalliakos, Ian Farrer +4
We demonstrate the in-plane emission of highly-polarized single photons from an InAs quantum dot embedded into a photonic crystal waveguide. The spontaneous emission rates are Purc…
Towards a quantum representation of the ampere using single electron pumps
S. P. Giblin, M. Kataoka, J. D. Fletcher +6
Electron pumps generate a macroscopic electric current by controlled manipulation of single electrons. Despite intensive research towards a quantum current standard over the last 2…
