THIS PAGE IS OBSOLETE. I have moved to Berlin.
Welcome to the homepage of Emil Johansson Bergholtz! I am a theoretical physicist ("Distinguished PKS Postdoctoral Fellow")
at the Max Planck Institute for the Physics of Complex Systems (MPI-PKS) in Dresden, Germany. Within MPI-PKS I'm associated with the condensed matter group lead by Roderich Moessner.
My primary research interests lie in the field of strongly correlated quantum matter, and in particular, my focus has been on various phases of the (fractional) quantum Hall system. Lately I've also had interests in frustrated quantum magnets (in 2 and 3D) and exotic 1D spin chains as well as in entanglement properties of strongly correlated states. In particular present projects include: One-dimensional limits of the fractional quantum Hall system Entanglement in fractional quantum Hall states Valence bond solids on the hyper-kagome lattice Unusual spin chains in connection with quantum Hall states

I'm interested in quantum physics, and in particular in systems where strong interactions and lead to novel phenomena. My research efforts during my time as a PhD student concentrated on the fractional quantum Hall (FQH) effect. The main theme of my work has been to develop a one-dimensional description of various phases of the FQH system. I also looked into the conformal field theory (CFT) description of (some of) these phases.
New directions in my research include frustrated (quantum) magnetism, spin chains/integrable models and concepts of quantum information in condensed matter systems.
I enjoy giving public popular science talks as well as specialized seminars. Here is a recent popular science talk (in Swedish, a short version) OrdningOchReda.pdf, a scientific talk on the fractional quantum Hall effect given at ENS, Paris: Paris08.pdf
My recent (2010) abstracts are summarized in the following figure:
