Congratulations to Lance Li, my PhD student on the publication of his first paper. It shows how the quantum imaginary time evolution operator can be used to solve nuclear density functional theory on a quantum computer. Physical Review C published the paper today at Phys. Rev. C. 109, 044322 (2024). It’s open access so viewable by all.

A recent paper by Li et al. introduced a variance minimization quantum algorithm. As one of their examples, they took a much-used nuclear physics case: A one-body model of the deuteron. Unfortunately, their presentation was a bit problematic, so I wrote a comment to submit to the journal (Physica Scripta) to try to correct the record. The comment was rejected by the editor, so I present the comment here instead, for the record - link at end of post. I would have put it on the arXiv, but they don’t publish comments of papers unless those papers are in the arXiv.

We (Bharti Bhoy and I) have been working on developing quantum computing algorithms to tackle the nuclear shell model.

A new paper appeared today in Physics Letters B, here, which features the work of now-graduated PhD student Iain Lee, on friction in heavy ion reactions. The reaction studied was 16O + 92Zr, prompted by a previous experimental study which suggested that the reaction mechanism was notably different to that of 16O + 90Zr because of the higher density of states caused by the two neutrons outside of the closed shell. I got involved in the calculations by providing some time-dependent Hartree-Fock calculations to see what this kind of microscopic approach said about the rate of developement of the neck during fusion. One unusual aspect of this paper is that it was submitted less than two weeks ago. The editors sent it out for review extremely quickly, and referee comments came back quickly. They were serious comments and the referee had clearly read the paper well, and was an expert in the area. My colleauge Alexis, who was the coresponding author, worked on the response straight away, and the editor and referee accepted the response, meaning that the paper was accepted within a week, and has since apperaed (as an uncorrected proof) today, less than two weeks since submission.
I have never experienced such a quick process in publishing a scientific research paper!

Last week I and many of my group attended the Institute of Physics joint High Energy Physics, Astroparticle Physics, and Nuclear Physics Conference in Liverpool. I was honoured to be asked to give a plenary talk to the whole conference on the subject of quantum computing in nuclear structure. My colleague in the UK nuclear theoretical physics community, Jacek Dobaczewski from the University of York, took this picture of me as I talked:
