[Todos] Recordatorio seminario IFLP/Dto Fisica, jueves 10:30hs

[Maria Virginia Manias]

*SEMINARIOS  DEL IFLP y DEL DEPARTAMENTO*

*JUEVES 27 de ABRIL – 10:30 hs*

*AULA CHICA*


*TÍTULO**: **"2D Critical Casimir forces between inhomogeneous boundaries"*





*EXPOSITOR:* *Raoul Santachiara*

*Laboratoire de Physique Theorique et Modeles Statistiques de la Universite
de Paris-Sud*


*Resumen:* Systems as diverse as binary mixtures and inclusions in
biological membranes, and many more can be described effectively by
interacting spins. When the critical fluctuations in these systems are
constrained by boundary conditions, critical Casimir forces (CCF) emerge.
Here we analyze CCF between boundaries with alternating boundary conditions
in two dimensions, employing conformal field theory (CFT). Interestingly we
will discuss about a new form of the Szego-Widow theorem for block Toepliz
matrices
