DESCRIPTION:Emergent supersymmetry at the Ising-Kosterlitz-Thouless multicr
 itical point\nLiza Huijse\, Stanford University\nSupersymmetry is a powerf
 ul concept in high-energy physics\, but is often thought to require too mu
 ch fine-tuning to be relevant for condensed matter systems. However\, in t
 his talk\, I will show that supersymmetry emerges in a large class of mode
 ls with a Z2 and U(1) symmetry at the multicritical point where the Ising 
 and Kosterlitz-Thouless transition coincide. To arrive at this result we p
 erformed a detailed renormalization group analysis of the multicritical th
 eory including all perturbations allowed by symmetry. I will sketch this a
 nalysis and show how it reveals an intricate flow diagram with a marginall
 y irrelevant direction that preserves part of the supersymmetry of the fix
 ed point. The flow along this special line is very slow and we discuss the
  implications of this slow flow.
