Seminar “Quantum Field Theory”
Date and Time: Wednesday, 29 April 2020, at 2:00 PM
Venue: Online conference in Zoom, Bogoliubov Laboratory of Theoretical Physics
Seminar topic: «Renormalization group investigation of critical phenomena in static and dynamic models»
Speaker: Georgii Kalagov
Abstract:
We will take a brief look at the work has been done recently. In the first part phase transitions in matrix field models with a complex skew-symmetric field and a hermitian one are explored via both the ε-expansion and the functional renormalization group. In most cases, these models are shown to undergo fluctuation-driven first-order phase transitions.
The use of the renormalization group to reveal the effect of developed turbulence on the critical behaviour of fluids is outlined in the second part.
