Quantum tunnelling in the context of SARS-CoV-2 infection [PDF]

open access: yesScientific Reports, 2022
The SARS-CoV-2 pandemic has added new urgency to the study of viral mechanisms of infection. But while vaccines offer a measure of protection against this specific outbreak, a new era of pandemics has been predicted.

Combined quantum tunnelling and dielectrophoretic trapping for molecular analysis at ultra-low analyte concentrations [PDF]

open access: yesNature Communications, 2021
Quantum tunnelling offers a unique opportunity to study nanoscale objects with atomic resolution using electrical readout. However, practical implementation is impeded by the lack of simple, stable probes, that are required for successful operation ...

Aromaticity switching by quantum tunnelling [PDF]

open access: yesChemical Science
Carbon tunnelling in pentalene-based polycyclic molecules enables ultrafast π-bond rearrangements switching local aromaticity/antiaromaticity, or leading to a quantum “Schrödinger's aromaticity cat” in a coherent tunnelling regime.

Quantum computing for quantum tunneling [PDF]

open access: yesPhysical Review D, 2021
We demonstrate how quantum field theory problems can be embedded on quantum annealers. The general method we use is a discretisation of the field theory problem into a general Ising model, with the continuous field values being encoded into Ising spin chains.

Quantum battles in attoscience: tunnelling [PDF]

open access: yesThe European Physical Journal D, 2021
Abstract What is the nature of tunnelling? This yet unanswered question is as pertinent today as it was at the dawn of quantum mechanics. This article presents a cross section of current perspectives on the interpretation, computational modelling, and numerical investigation of tunnelling processes in attosecond physics
