Experimental observation of quantum mechanical fluorine tunnelling [PDF]

open access: yesNature Communications
Quantum mechanical tunnelling occurs when a molecule transforms between two states separated by a finite energy barrier that cannot be overcome thermally. To date, it has been observed for elements up to oxygen.

The hydrogen bond rotation of confined water affected by quantum resonance tunnelling

open access: yesFrontiers in Physics, 2022
In this work, we report quantum tunnelling effects on the confined water chain flipping, different from the spatial size and even electronic correlation effects of the confinement environment.

Quantum Tunneling on Graphs [PDF]

open access: yesCommunications in Mathematical Physics, 2012
We explore the tunneling behavior of a quantum particle on a finite graph, in the presence of an asymptotically large potential. Surprisingly the behavior is governed by the local symmetry of the graph around the wells.

Witnessing quantum correlations in two coupled quantum dots under intrinsic decoherence

open access: yesAlexandria Engineering Journal, 2023
The influences of intrinsic decoherence, tunnelling rates, and Coulomb coupling interaction on the behaviour of negativity, quantum coherence and the measurement-induced disturbance of two coupled quantum dot molecules are discussed.

Fundamental limits of electron and nuclear spin qubit lifetimes in an isolated self-assembled quantum dot

open access: yesnpj Quantum Information, 2021
Combining external control with long spin lifetime and coherence is a key challenge for solid state spin qubits. Tunnel coupling with electron Fermi reservoir provides robust charge state control in semiconductor quantum dots, but results in undesired ...

Quantum Tunnelling Effects in the Guanine-Thymine Wobble Misincorporation via Tautomerisation [PDF]

open access: yes, 2022
The misincorporation of a non-complimentary DNA base in the polymerase active site is a critical source of replication errors that can lead to genetic mutations.

On the effect of decoherence on quantum tunnelling

open access: yesSN Applied Sciences, 2021
This work proposes a series of quantum experiments that can, at least in principle, allow for examining microscopic mechanisms associated with decoherence.

Theoretical characterisation of electron tunnelling from granular activated carbon to electron accepting organisms in direct interspecies electron transfer

open access: yesScientific Reports, 2022
Direct interspecies electron transfer (DIET) has been identified as an efficient metabolism between symbiotically interacting organisms. One method of DIET uses conductive materials (e.g., granular activated carbon (GAC)) as a medium to shuttle electrons

Investigation into the integration of a resonant tunnelling diode and an optical communications laser: model and experiment [PDF]

open access: yes, 2007
A resonant tunnelling diode has been monolithically integrated with an optical communications laser [the resonant tunnelling diode (RTD-LD)] to form a simple optoelectronic integrated circuit (OEIC) that is a novel bistable device suitable for an optical
