SUMMARY:Dynamics and implications of black hole decay\, Preliminary Ex
 am\, Puxin (David) Lin\, Physics PhD Graduate Student
DESCRIPTION:Black holes exhibit gravitational and quantum effects that
  lead to potential observables and insights into Effective Field Theor
 ies (EFTs) with gravity. In this presentation\, I will discuss the cha
 rge radiation of black holes and its theoretical implications. The com
 putation of charged particle creation\, the Schwinger effect\, of blac
 k holes\, will be presented. For highly charged (extremal) black holes
 \, the emission spectrum truncates below a threshold value of the part
 icle’s charge-to-mass ratio. This result will then be used to formul
 ate the Weak Gravity Conjecture (WGC)\, which provides a potential con
 straint on consistent EFTs. Features of black holes in de Sitter space
  (\\Lambda>0)\, such as their thermodynamics and (in)stabilities will 
 be discussed.
