I have finished a post-doc here at IPhT with Grégoire Misguich and Marco Schiró; we have studied Lindblad driven-dissipative dynamics of quantum spins on lattices in various dimensions, using exact matrix product operators and an approximate dynamical approach that we developed. I was supported by IRS-IQUPS of Univ. Paris-Saclay and by LabEx PALM.
In my previous postdoc at LPTMS, CNRS, Université Paris Sud, I studied strong interactions of trapped ions and ultracold atoms, and I was supported by a Marie Curie Intra European Fellowship and by the 2013-2014 Chateaubriand fellowship of Campus France and the French embassy in Israel.
