Simulation of direct source-to-drain tunnelling using the density gradient formalism: Non-Equilibrium Greens Function calibration [PDF]
, 2002 Quantum mechanical confinement effects, gate, hand-to-hand and source-to-drain tunnelling will dramatically affect the characteristics of future generation nanometre scaled devices.

Site-specific electrical contacts with the two-dimensional materials
Nature Communications, 2020 Here, the authors use in situ transmission electron microscopy to measure the interface properties of electrical contacts with MoS2, ReS2, and graphene, and find that direct quantum tunnelling across van-der-Waals-bonded interfaces is more favourable ...

Manipulating tunnelling gateways in condensed phase isomerization
Natural Sciences, 2023 When a chemical reaction occurs via tunnelling, a simple mass‐dependence is expected, where substitution of atoms by heavier isotopes leads to a reduced reaction rate.

Macroscopic matter wave quantum tunnelling [PDF]
, 2019 Quantum tunnelling is a phenomenon of non-equilibrium quantum dynamics and its detailed process is largely unexplored. We report the experimental observation of macroscopic quantum tunnelling of Bose–Einstein condensate in a hybrid trap.

, 2002 Dedicated to the memory of Professor Michael Marinov, a friend, a colleague and a man of firm principles who believed in his right to live in peace in Israel, the land of his ancestors (Latex, 5 eps figures, uses sprocl style), to be published in the Michael Marinov Memorial Volume, Eds. M. Olshanetsky and A. Vainshtein (World Scientific, 2002)

Tunneling decay of false domain walls: the silence of the lambs [PDF]
, 2015 We study the decay of "false” domain walls, which are metastable states of the quantum theory where the true vacuum is trapped inside the wall, with the false vacuum outside.

Fermi edge singularities in transport through lateral GaAs quantum dots
New Journal of Physics, 2017 We measure tunnelling currents through electrostatically defined quantum dots in a GaAs/AlGaAs heterostructure connected to two leads. For certain tunnelling barrier configurations and high sample bias we find a pronounced resonance associated with a ...

Microwave-induced conductance replicas in hybrid Josephson junctions without Floquet—Andreev states
Nature Communications, 2023 Light–matter coupling allows control and engineering of complex quantum states. Here we investigate a hybrid superconducting–semiconducting Josephson junction subject to microwave irradiation by means of tunnelling spectroscopy of the Andreev bound state

Large effects from small QCD instantons: making soft bombs at hadron colliders
Journal of High Energy Physics, 2020 It is a common belief that the last missing piece of the Standard Model of particles physics was found with the discovery of the Higgs boson at the Large Hadron Collider.

Quantum Tunnelling to the Origin and Evolution of Life. [PDF]
Curr Org Chem, 2013 Quantum tunnelling is a phenomenon which becomes relevant at the nanoscale and below. It is a paradox from the classical point of view as it enables elementary particles and atoms to permeate an energetic barrier without the need for sufficient energy to
