Research Area

Condensed Matter Theory --- the study of coherence and correlations in many-particle systems.

Primary research themes:

• non-equilibrium dynamics;

• many-particle phenomena in laser-cooled trapped atomic gases;

• using entanglement measures (from quantum information theory) to study condensed matter states and phenomena;

• topological order and other unconventional ordering.

Postdocs interested in working on any of these topics: please contact me by email.

Most of my papers are available as preprints on arxiv.org.

Most are on `cond-mat', except for a couple of exceptions, e.g., a q-bio and a cs.LG preprint.

Employment trajectory

I am currently a faculty member at Maynooth University, in Ireland, in the greater Dublin area. When I joined, our Department was called the Department of Mathematical Physics, for reasons unknown to me. Since then it has been renamed and is now called the Department of Theoretical Physics.

From late 2006 to early 2016, I was a research scientist at the Max-Planck Institute for the Physics of Complex Systems (MPI-PKS) in Dresden, Germany.
I was associated with the Condensed Matter Department within MPI-PKS.
For part of my time in Dresden, I held a ``Distinguished PKS postdoctoral fellow'' position; one of three such positions at the MPI-PKS.
Later, as a longer-term Staff Scientist I directed a group of researchers (of varying sizes at various times), mostly focusing on the physics of quantum systems out of equilibrium.

My first postdoctoral appointment (Nov 2003 -- Sep 2006) was in Utrecht university, the Netherlands, working with Henk Stoof's group, at the Institute for Theoretical Physics,

I did my Ph.D. at the Physics Department in Rutgers University, New Jersey. I was at Rutgers from Fall 1997 till September 2003. I worked with the Rutgers quantum condensed matter group and my PhD advisor was Andrei E Ruckenstein.
