FIELD OF SCHOLARSHIP: Physics

BIOGRAPHICAL NOTE:

I obtained an MSc and later a PhD in Physics at the Eötvös University, Budapest. Afterwards I spent 3 years (2010-2012) as a postdoctoral researcher in Amsterdam, at the University of Amsterdam. In the first year I was applied by Jean-Sébastien Caux, and afterwards I got the VENI grant of the NWO (The Netherlands Organisation for Scientific Research). In 2013 I returned to Budapest to work in the recently started research group of Gábor Takács (MTA-BME “Momentum’’ Statistical Field Theory Research Group), and I also obtained the Magyary Zoltán Fellowship. Currently I am applied by the Hungarian Academy of Sciences through the Premium Postdoctoral Program. In 2014 I won the hungarian “Junior Prima” prize in the category of “Hungarian Science”.

DETAILS OF RESEARCH:

In my research I have been dealing with the so-called Integrable Models of Quantum Mechanics. These are special theories describing interacting many-body systems, that can be solved exactly without the need to use approximate methods or computer simulations. The models that I have been investigating include models of quantum magnetism (the Heisenberg spin chain), interacting quantum gases (the Lieb-Liniger model), or exactly solvable Quantum Field Theories. These models are interesting for two main reasons: First of all it is important to study examples of quantum behaviour where analytic solutions can be found. Second, these models describe real materials and/or can be realized experimentally, and we can give predictions for physical properties of these systems. Recently I have been interested in non-equilibrium situations. One of the fundamental questions is how can the laws of statistical physics be derived from the underlying microscopic quantum theory. Our research played an important role in clarifying the statistical physics of integrable models, which are actually an exception to the standard laws in many respects.
