Results in Hungarian
A véges hőmérsékletű térelméletekben elért – Nature-ben is közölt – eredményünk szerint az ősrobbanás utáni kvark-hadronikus anyag átmenet folytonos, nem fázisátátalakulás. Rácstérelméleti módszerekkel megadtuk ezen átmenet karakterisztikus hőmérsékletét. Az integrálható térelméletek alkalmazhatók a kondenzált anyagok fizikájától a nyílt húrelméleten keresztül egészen a részecskefizikáig. Jelentős lépést tettünk a racionális konform térelméletek osztályozása felé. A statisztikus fizika területén külön figyelmet szenteltünk az egyensúlytól távoli jelenségek közül a frontoknak. A kémiai, biológia és mágneses frontok mozgását, alakváltozásait írtuk le és szabályozásukat dolgoztuk ki. A fizikai mennyiségek extrém értékeinek statisztikája az alkalmazások szempontjából is fontos új terület, melyen belül transzportjelenségek és 1/f típusú zaj ingadozásait jellemző mennyiségek maximumának eloszlását adtuk meg. A diszlokációrendszerek statisztikus fizikai vizsgálata segítségével több áttörést értünk el. A környezeti áramlások témakörében a Kármán Laboratórium aktív kutatóhellyé fejlődött. A frontoktól kezdve a ciklonképződésig számos kísérletet végeztünk. Kiemelendő, hogy egy forgókádbeli turbulenciában a hőmérséklet fluktuációinak statisztikája reprodukálja a földi meteorológiai állomások adataiét. A kísérletek a klímaváltozás vizsgálatában is ígéretesek. A pályázati időszakban 21 doktorandusz témavezetését láttuk el.
Results in English
Our result - published also in Nature - on finite temperature field theories states that the quark-hadronic matter transition after the Big Bang happened continuously, not like a phase transition. We determined the characteristic crossover temperature using lattice field theoretical methods. Integrable field theories have applications from condensed matter physics to open string theory to particle physics. We made a major step towards the classification of rational conformal field theories. In statistical physics special attention has been payed to fronts, a phenomenon in far from equilibrium systems. We described and controlled motion and shapes of fronts in chemical, biological, and magnetic systems. Extreme statistics of physical quantities is a new area also important from the viewpoint of applications, where we determined the distribution of maxima in transport phenomena and in quantities characterizing fluctuations of 1/f-type noises. Several breakthroughs were achieved by means of statistical physical studies in dislocation systems. As to the topic of environmental flows, the von Karman Laboratory has become an active research unit where experiments ranging from fronts to cyclone-genesis have been carried out. As a highlight, in the turbulence from a rotating tank the statistics of temperature fluctuations reproduced that of data from meteorological stations. The experiments are promising for studies in climate change. In the grant period we supervised 21 PhD students.
