Quantum Coherent Multielectron Processes in an Atomic Scale Contact
Peter-Jan Peters, Fei Xu, Kristen Kaasbjerg +3
The light emission from a scanning tunneling microscope operated on a Ag(111) surface at 6 K is analyzed from low conductances to values approaching the conductance quantum. Optica…

Dynamical Coulomb blockade theory of plasmon-mediated light emission from a tunnel junction
Fei Xu, Cecilia Holmqvist, Gianluca Rastelli +1
Inelastic tunneling of electrons can generate the emission of photons with energies intuitively limited by the applied bias voltage. However, experiments indicate that more complex…

Over-Bias Light Emission due to Higher Order Quantum Noise of a Tunnel Junction
F. Xu, C. Holmqvist, W. Belzig
Understanding tunneling from an atomically sharp tip to a metallic surface requires to account for interactions on a nanoscopic scale. Inelastic tunneling of electrons generates em…
