Publication news

16 October 2018

Some news about active collaborations: our paper about the most general XYZ Richardson-Gaudin model in an arbitrary magnetic field just appeared on arXiv. While XYZ models generally do not allow for an arbitrary magnetic field, we show how such a field can be introduced through the restriction to spin-1/2 models, which relaxes the usual integrability constraints. Joint work with Stijn De Baerdemacker, Alexandre Faribault and his Ph.D. student Claude Dimo from the University of Lorraine, following my one-week stay at Lorraine earlier this year. Hopefully, this should allow for a more realistic description of the decoherence of central spin models. All comments are welcome!

On to the next state of the publication process - the paper with Eyzo Stouten, Mikhail Zvonarev, Jean-Sébastien Caux and Vladimir Gritsev on generalized Lieb-Liniger models just got accepted for publication in Journal of Physics A: Mathematical and Theoretical and should appear online shortly.

Postdoc and website

26 September 2018

This week my FWO Ph.D. fellowship officially ended, and after some interesting years I’ve had to say bye to both Ghent University and Ghent itself. Moving on to postdoc life, I’ve just arrived in Boston to start a postdoc with Anatoli Polkovnikov at the Condensed Matter Theory group at Boston University, with support from the Belgian American Education Foundation. Hopefully more updates soon!

And in other (more obvious) news, I have a personal website!
