`Induced Chern-Simons Terms from Massive Matter - A String Theorist's Perspective'
Abstract:
It's been a point of much interest that Chern-Simons terms can be created in an
action by integrating out massive fermions to one-loop. This has interesting
applications when considering Aharony and Giveon Kutasov Dualities. These are
3d electric-magnetic (low energy) dualities where the former applies to cases
with zero Chern-Simons coefficient and the latter applies to theories with
non-zero Chern-Simons coefficient. So we see that by integrating out massive
fermions we can alter the Chern-Simons level and thus switch between these
dualities. We look at this for numerous massive fermions. We then look at this
for bifundamental fermions, however the bifundamental case is a work in
progress.
