Quantum beats in the polarization response of a dielectric to intense few-cycle laser pulses
New Journal of Physics, 2013 We have investigated the polarization response of a dielectric to intense few-cycle laser pulses with a focus on interband tunnelling. Once charge carriers are created in an initially empty conduction band, they make a significant contribution to the ...

Experimental observation of quantum mechanical fluorine tunnelling [PDF]
Nature CommunicationsQuantum 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.

Quantum computing for quantum tunneling [PDF]
Physical 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.

The hydrogen bond rotation of confined water affected by quantum resonance tunnelling
Frontiers 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 battles in attoscience: tunnelling [PDF]
The 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
