SUMMARY:Confined Monopoles and Failure of the Lattice Weak Gravity Conject

DESCRIPTION: The Weak Gravity Conjecture and its various refinements form 
 a cornerstone of the swampland program. While many examples satisfy the La
 ttice Weak Gravity Conjecture (LWGC)\, where a superextremal state is pres
 ent at every site of the charge lattice\, there are some examples where on
 ly a (finite index) sublattice of superextremal states are present. In thi
 s talk\, we will identify and explore a common feature of these LWGC viola
 ting theories: a magnetic superlattice of fractionally charged confined mo
 nopoles. We will study several quantitative features of these confined mon
 opoles and their flux tubes\, and we will study the extension to theories 
 with nonabelian gauge groups. In the process\, we will encounter novel exa
 mples of LWGC violation.
