Update on the time-dependent methods special topic

 I last posted an update back in June about the Special Topic in Frontiers in Physics that I am co-editing.   Then, a new article on solitons in nuclear reactions had just been published.  This was actually followed a few days later with another paper, and then there has been a fallow period while the last few papers go through refereing, proofing, and publication.  Today, the next of those was published. so let me briefly mention the two new papers since June:

Marc Verriere and David Regnier have written a review on the time-dependent Generator Coordinate Method.  In fact, they discuss a number of related models which all share the character of mixing multiple Slater determinant wave functions to represent complex nuclear phenomena (reactions, fission) in which there is a significan change over time of the quantum state, and for which a time-dependent method is appropriate.  It's a nice contribution the Special Topic, covering one of the current hot methods in nuclear theory.  I can say this since I have a PhD student working on something that can be termed time-dependent Generator Coordinate Method, though it is not quite the same as the methods presented by Verriere and Regnier.  

 The other paper, published today, is written by a University of Surrey undergradute student who took a year-long research placement at Peking University in Beijing, China.  He used time-depedent Hartree-Fock (TDHF) to look at the part of the fission pathway near scission where the TDHF method is applicable, and to study how different parameterisation of the nuclear force give different predictions for the pathway to fission.  It's a short piece of original research, which complements nicely the mix of other research and review articles in the Special Topic.  I worked on this project with Marko and his host supervisor, and am co-author on the paper.  I took the liberty of using a picture from this paper as an accompaniment to this blog post.

Once the two remamining papers appear,  on spontaneous fission and collective dynamics with a transport model, have appeared, the whole Special Topic will be avaiable as a free e-book, in pdf and epub format, so get your Kindles ready.
