DESCRIPTION:Speakers: Dr. RAYA\, Alfredo (IFM-UMSNH)\nWe study the gap equ
 ation for the fermion propagator in Reduced QED coupled with a Chern-Simon
 s term. In the ordinary theory\, the electromagnetic coupling needs to exc
 eed a critical value in order for mases to be generated. Adding the influe
 nce of a Chern-Simons term\, it is observed that there exists a critical v
 alue of the theta-term above which chiral symmetry is restored regardless 
 the strength of the coupling. These findings are of direct relevance in gr
 aphene physics to understand the semimetal-insulator transition in the pre
 sence of parallel electric and magnetic fields. Connections with the chira
 l magnetic effect are also explored.\n\nhttps://indico.nucleares.unam.mx/e
