DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IFTWeb/55/">
 Positive magnetoresistance induced by hydrodynamic fluctuations in chiral 
 media</a>\nby Noriyuki Sogabe (Institute of Modern Physics\, Lanzhou\, Chi
 na) as part of IFT-Madrid Webinars\n\n\nAbstract\nWe analyze the combined 
 effects of hydrodynamic fluctuations and chiral magnetic effect (CME) for 
 a chiral medium in the presence of a background magnetic field. Based on t
 he recently developed non-equilibrium effective field theory\, we show flu
 ctuations give rise to a CME-related positive contribution to magnetoresis
 tance\, while the early studies without accounting for the fluctuations fi
 nd a CME-related negative magnetoresistance. At zero axial relaxation rate
 \, the fluctuations contribute to the transverse conductivity in addition 
 to the longitudinal one.\n
