Lattice Gauge Theory group
We are the lattice gauge theory group at the Eotvos University
in Budapest, part of the Department of Theoretical Physics at the
Faculty of Science. Since 2011 we are a CUDA Research Center.
Currently there are seven members and we are seeking new ones. Positions are available for PhD students and postdocs for 2 - 4 years appointments. If you are interested please email Sandor Katz at katz {at} bodri {dot} elte {dot} hu or Daniel Nogradi at nogradi {at} bodri {dot} elte {dot} hu.
Our activities are funded by the EU Framework Programme 7 grant (FP7/2007-2013)/ERC No 208740.
Research
Our primary interests are:
- Chiral symmetry restoration and deconfinement in QCD with Wilson fermions
- Finite chemical potential
- QCD hadron spectrum
- Eigenvalue distributions of the overlap Dirac operator
- Strongly interacting Higgs sector - technicolor
- Conformal gauge theories
For students
Our group offers TDK, diploma and PhD topics in Lattice Field Theory.
Please contact Sandor: katz {at} bodri {dot} elte {dot} hu
or Daniel: nogradi {at} bodri {dot} elte {dot} hu
in case you are interested.
Current topics include:
- QCD thermodynamics
- SU(N) gauge theory with topological lattice action
- O(3) non-linear sigma model with topological term
- Beyond Standard Model - technicolor

Computing
Our group has access to a number of high performance computer installations in Europe and also maintains several PC and GPU clusters on site in Budapest.
Our primary resource is a 128 node cluster with two NVIDIA GTX 275 cards in each node, hosted in Budapest. There is also a 60 node cluster with one NVIDIA GTX 8800 card per node.
In addition we also have access to the Juropa cluster and the BlueGene/P installation in Forschungszentrum Juelich, Germany.
Our collaboriation with the University of Wuppertal, Germany also allows us to use several PC and GPU clusters there.
In case you are interested you can see a map of GPU cluster installations throughout the world dedicated to Lattice Gauge Theory.
For visitors
You will most likely stay at the Peregrinus hotel in the downtown area of Pest.
The simplest way to get to/from your hotel from/to the airport is by taxi. Ask for the fixed rate which should be around 20-22 euros.
Our department is on the Buda side of the Danube very close to the Petofi Bridge and it is about a 30-35 minutes walk from the hotel:
You exit your hotel, walk past the Great Market Hall (definitely worth a closer look if you have about half an hour or an hour!) and the Corvinus University, cross the Danube on the Szabadsag Bridge and walk South. You will pass the Budapest University of Technology and the Petofi Bridge and our building will be a redish seven-story building on the right. The Department of Theoretical Physics is on the first floor on the Danube facing side of the building:
