RCPStatistical physics of dislocationsTuesday, 17 March 2026, 10:00, KFKI 
Campus, Bldg. 1, 2nd floor, Conference RoomThe concept of dislocations was 
introduced in 1934 by Hungarian scientists Orován and Polányi, along with the 
British scientist Taylor. Since then, there has been a continuous research 
activity in this field in Hungary. In the first part of the talk, some key 
results obtained on dislocations in Hungary during the past 50 years are 
summarized. Nowadays, the main focus of dislocation research is to develop an 
appropriate statistical physics-based continuum theory of dislocations. Since 
dislocations form a dissipative system with long-range interactions, and the 
dislocation motion is restricted to slip planes, the traditional method of 
statistical physics cannot be applied in a straightforward manner. In the 
talk, a systematic approach is presented that leads to a phase field-like 
theory.   Minden érdeklődőt szívesen látunk! - Everyone is welcome to
