DESCRIPTION:Speaker: Ibrahim Akal\nhosted by Zhanybek Alpichshev\nAbstract:
  Pair creation via the Schwinger mechanism is a fundamental prediction in 
 quantum field theory. Unfortunately\, a direct experimental verification o
 f this purely nonperturbative phenomenon has not yet been achieved\, since
  the critical field strength is extremely large. Recent developments have 
 shown that constructing the field in an appropriate way may effectively re
 duce the width of the tunnelling barrier and thus result in a drastic enha
 ncement in the pair production rate. In this talk\, I will present the bas
 ic idea behind this dynamical mechanism. Afterwards\, I will discuss the p
 ossibility of observing analog effects in condensed matter systems. In par
 ticular\, I will consider the case of graphene monolayers and argue that t
 he described mechanism may be tested with present-day laser technology.
