Conditional statistics of electron transport in interacting nanoscale conductors
Eugene V. Sukhorukov,Andrew N. Jordan,Simon Gustavsson,Renaud Leturcq,Thomas Ihn,Klaus Ensslin +5 more
TL;DR: In this article, it was shown that even the operation of an effectively non-invasive QPC detector can statistically alter the system's behaviour, by observing a particular QPC current, the statistical distribution of the QD conditional current undergoes a substantial change in comparison to that expected for unconditional shot noise.

Fluctuation theorem for transport in mesoscopic systems
David Andrieux,Pierre Gaspard +1 more
TL;DR: The fluctuation theorem for currents is applied to several mesoscopic systems on the basis of Schnakenberg's network theory, which allows one to verify its conditions of validity as mentioned in this paper.

TL;DR: Electronic nanothermometry is realized by measuring local current fluctuations, or shot noise, associated with ultrafast hot-electron kinetic processes (~21 terahertz) using a scanning and contact-free tungsten tip as a local noise probe and directly visualize hot-Electron distributions before their thermal equilibration with the host gallium arsenide/aluminium gallium arsenic arsenide crystal lattice.

Single-electron quantum tomography in quantum Hall edge channels
Charles Grenier,Rémy Hervé,Erwann Bocquillon,François Parmentier,Bernard Plaçais,Jean-Marc Berroir,Gwendal Fève,Pascal Degiovanni +7 more
TL;DR: In this paper, the authors proposed a quantum tomography protocol to measure single electron coherence in quantum Hall edge channels analogous to homodyne tomography in quantum optics, which is a major step in electron quantum optics with applications ranging from characterization of single to few electron sources to quantitative studies of single electron decoherence in nanostructures.

Positive noise cross-correlation in hybrid superconducting and normal-metal three-terminal devices
Jian Wei,Venkat Chandrasekhar +1 more
TL;DR: In this article, positive noise cross-correlations in a hybrid system consisting of a superconductor sandwiched between two normal metals provides evidence that Cooper pairs can be split into pairs of spatially separated, entangled electrons.

Transition from metallic to tunneling regimes in superconducting microconstrictions: Excess current, charge imbalance, and supercurrent conversion
TL;DR: In this paper, the Bogoliubov equations were used to model the transmission and reflection of particles at the tunnel junction of normal-superconducting micro-constriction contacts, and a simple theory for the $I\ensuremath{-}V$ curves of normal superconducting contacts was proposed to describe the crossover from metallic to tunnel junction behavior.
