An open quantum systems approach to proton tunnelling in DNA [PDF]
Communications Physics, 2022 The genetic stability of DNA suffers from proton transfer along the hydrogen bonds that can lead to tautomerisation, creating mutations. The authors theoretically examine the tautomerisation of the GuanineCytosine (G-C) nucleotide base-pair using an open

Heavy-Atom Quantum Tunnelling in Spin Crossovers of Nitrenes. [PDF]
Angew Chem Int Ed Engl, 2022 We simulate two recent matrix‐isolation experiments at cryogenic temperatures, in which a nitrene undergoes spin crossover from its triplet state to a singlet state via quantum tunnelling.

Sensing the quantum limit in scanning tunnelling spectroscopy [PDF]
Nature Communications, 2016 The tunnelling current in scanning tunnelling spectroscopy has often been treated by a continuous charge flow, which lacks proper treatment of charge quantization. Here, Ast et al.

Vibronic effects on the quantum tunnelling of magnetisation in Kramers single-molecule magnets. [PDF]
Nat Commun, 2023 Single-molecule magnets are among the most promising platforms for achieving molecular-scale data storage and processing. Their magnetisation dynamics are determined by the interplay between electronic and vibrational degrees of freedom, which can couple

Enhanced flexoelectricity at reduced dimensions revealed by mechanically tunable quantum tunnelling. [PDF]
Nat Commun, 2019 Flexoelectricity is a universal electromechanical coupling effect whereby all dielectric materials polarise in response to strain gradients. In particular, nanoscale flexoelectricity promises exotic phenomena and functions, but reliable characterisation ...

Quantum Tunnelling Driven H2 Formation on Graphene. [PDF]
Journal of Physical Chemistry Letters, 2022 It is commonly believed that it is unfavorable for adsorbed H atoms on carbonaceous surfaces to form H2 without the help of incident H atoms. Using ring-polymer instanton theory to describe multidimensional tunnelling effects, combined with ab initio ...

Field- and temperature-dependent quantum tunnelling of the magnetisation in a large barrier single-molecule magnet. [PDF]
Nat Commun, 2018 Understanding quantum tunnelling of the magnetisation (QTM) in single-molecule magnets (SMMs) is crucial for improving performance and achieving molecule-based information storage above liquid nitrogen temperatures. Here, through a field- and temperature-
