Quantum Battles in Attoscience -- Tunnelling
Cornelia Hofmann, Alexander Bray, Werner Koch +2
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 pe…
Fermions with long and finite range interactions on a quantum ring
A. W. Bray, C. Simenel
Background: Idealised systems are commonly used in nuclear physics and condensed matter. For instance, the construction of nuclear energy density functionals involves properties of…
Revealing the Two-Electron Cusp in the Ground States of He and H2 via Quasifree Double Photoionization
S. Grundmann, V. Serov, F. Trinter +15
We report on kinematically complete measurements and ab initio non-perturbative calculations of double ionization of He and H2 by a single 800 eV circularly polarized photon. We co…
Dissecting strong-field excitation dynamics with atomic-momentum spectroscopy
A. W. Bray, U. Eichmann, S. Patchkovskii
Observation of internal quantum dynamics relies on correlations between the system being observed and the measurement apparatus. We propose using the center-of-mass (c.m.) degrees…
Effect of electron correlations on attosecond photoionization delays in the vicinity of the Cooper minima of argon
D. Hammerland, P. Zhang, A. Bray +10
Attosecond photoionization delays have mostly been interpreted within the single-particle approximation of multi-electron systems. The strong electron correlation between the photo…
Correlation enhancement of high-order harmonics generation in Xe
Alexander W. Bray, David Freeman, Sebastian Eckart +1
We consider the process of high-order harmonics generation (HHG) in the xenon atom enhanced by the inter-shell correlation between the valence 5p and inner 4d shells. We derive the…
