Seminario Francisco Correa

noviembre 12 @ 2:30 pm - 4:00 pm

Fecha y hora: Martes 12 de noviembre,14:30

Lugar: Seminario de Física Teórica, segunda planta

Ponente: Francisco Correa (Instituto de Ciencias Físicas y Matemáticas, Universidad Austral de Chile)

Título: PT deformation and intertwining operators of Calogero models

Abstract: In this talk we will discuss how different classes of Calogero models of identical particles are deformed away from hermiticity but retaining a symmetry, preserving the integrability structure. The interaction potential gets completely regularized, which adds to the energy spectrum an infinite tower of previously non-normalizable states. We also discuss some algebraic features of intertwining or shift operators, which lead to the existence of nonlinear conserved charges for integral values of the couplings, explaining an extra degeneracy of the energy levels.
