Zapraszamy na seminarium 19.10.2021

We have the pleasure to invite you to the Particle Theory Seminar on Tuesday, 

October 19 at 12:15:

Speaker: Dr Victor Ambrus (West University of Timişoara and Univ. of Frankfurt)

Title: Helical effects for thermal fermions

Abstract: Recent evidence from relativistic heavy ion collisions (HIC) 
experiments confirmed the global significance of the vorticity to 
polarisation transfer through the spin-orbit coupling predicted by the 
Dirac equation. A well-known example is the Chiral vortical effect (CVE) 
linking the flow of chirality to the local medium vorticity. This talk 
focusses on the novel helical vortical effect (HVE), which predicts also 
a flow of helicity. Used together, the CVE and HVE constitute a 
promising tool to analyze the polarization asymmetry between matter and 
anti-matter observed in lower-energy collisions. The thermodynamical 
modelling of helicity imbalance through the helicity chemical potential 
is proposed and its impact on wave-like excitations (the 
Helical-vortical wave) and the QCD phase diagram is discussed.


Seminar will take place in the seminar room D-2-02, however, we plan to have it

in hybrid mode. People interested in the on-line participation are kindly

requested to let us know by email and we will send zoom coordinates.
