The edge channels of the quantum Hall effect provide one dimensional chiral and ballistic
wires along which electrons can be guided in an optics‐like setup. Electronic propagation …

The quantum Hall (QH) effect represents a unique playground where quantum coherence of
electrons can be exploited for various applications, from metrology to quantum computation …

The study of heat transport has the potential to reveal new insights into the physics of
mesoscopic systems. This is especially true of those that show the integer quantum Hall …

We investigate the energy exchanges along an electronic quantum channel realized in the
integer quantum Hall regime at a filling factor of ν L= 2. One of the two edge channels is …

Confined to a two-dimensional plane, electrons in a strong magnetic field travel along the
edge in one-dimensional quantum Hall channels that are protected against backscattering …

Graphene is a very promising test bed for the field of electron quantum optics. However, a
fully tunable and coherent electronic beam splitter is still missing. We report the …

The chiral edge channels in the quantum Hall regime are considered ideal ballistic quantum
channels, and have quantum information processing potentialities. Here, we demonstrate …

A unique type of electron source has emerged which permits to inject particles in a
controllable manner, one at a time, into an electronic circuit. Such single-electron sources …

Bosonization technique for one-dimensional fermions out of equilibrium is developed in the
framework of the Keldysh action formalism. We first demonstrate how this approach is …

We report a study of one-dimensional subband splitting in a bilayer graphene quantum point
contact in which quantized conductance in steps of 4 e 2/h is clearly defined down to the …
