Measuring the arrival time of an electron wave packet using a dynamical potential barrier

Wanki Park, H. -S. Sim, Sungguen Ryu

A time-dependent potential barrier has been used to probe the arrival-time distribution of the wave packet of a hot electron by raising the barrier to block the packet upon arrival…

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…

Conductance of electrostatic wire junctions in bilayer graphene

Sungguen Ryu, Rosa López, Llorenç Serra

The conductance of electrostatic wire junctions in bilayer graphene, classified as trivial-trivial or trivial-topological regarding the confinement character on each junction side,…

Partition of Two Interacting Electrons by a Potential Barrier

Sungguen Ryu, H. -S. Sim

Scattering or tunneling of an electron at a potential barrier is a fundamental quantum effect. Electron-electron interactions often affect the scattering, and understanding of the…

Beating Carnot efficiency with periodically driven chiral conductors

Sungguen Ryu, Rosa López, Llorenç Serra +1

Classically, the power generated by an ideal thermal machine cannot be larger than the Carnot limit. This profound result is rooted in the second law of thermodynamics. A hot quest…

Asymmetric arms maximise visibility in hot-electron interferometers

Clarissa J. Barratt, Sungguen Ryu, Lewis A. Clark +3

We consider theoretically an electronic Mach-Zehnder interferometer constructed from quantum Hall edge channels and quantum point contacts, fed with single electrons from a dynamic…
