Flagship projects, research groups
This 'Momentum' research group, financed by the HAS and the BME, studies the dynamics of one-dimensional quantum systems, such as spin chains, one-dimensional Bose gases, and related quantum field theory models. Compared to higher dimensional systems, quantum effects and correlations between degrees of freedom play a much more important role in one dimension, resulting in numerous exotic phenomena. In a significant part of these phenomena the so-called integrability or its absence play a central role.
The main research objective of the Computational Magnetism research group is a theoretical and computational investigation of magnetic phenomena in bulk alloys, heterostructures and nano-particles. One of our tools is based on spin-models with first priciples calculation and Monte-Carlo and Langevin dynamics smiulations, the other on relativistic implementation of disordered local moment scheme which takes into account the interplay between the thermal spin-fluctuations and the electronic structure. We carry out our project within a broad international cooperation, including experimental and industrial partners.
Social networks are interesting complex systems where the agents are human beings. Besides their commercial and social interest physical methods opened new horizons in this fields. ICT based communications create a lot of data which can be analyzed and modeled to understand human society. Our group has access to many of such databases, like: mobile phone, IP phone services and the Hungarian social network site iwiw data and furthermore we are also interested in modelling the observed features.
Our BME-MTA Exotic Quantum Phases 'Momentum' Research Group consists of a group of young physicists, whose goal is to study interacting condensed matter and cold atomic systems by means of quantum field theoretical tools. We attempt to identify and describe exotic quantum phases and non-equilibrium dynamics of interacting low dimensional systems and interacting cold atoms, and to investigate non-equilibrium transport through nano-structures in the presence of strong interactions.
