Colóquio do Pós-Graduação: "The discrete charm of scale invariance in nuclear and atomic physics" - U. van Kolck, Institut de Physique Nucleaire d'Orsay and University of Arizona
Quinta-feira, Maio 03, 2018, 16:00

Abstract:

Nature is certainly not invariant under changes of scale. Phenomena and laws are characterized by parameters that determine their dimensions. However, while the complexity of some many-body systems may stem from a profusion of distinct scales, rich structures exist even when there is no more than one essential scale associated with discrete scale invariance. I will discuss how intrinsically quantum-mechanical structures with unique properties, sometimes labeled "Efimov physics", emerge in nuclear and some closely related atomic systems from a contact three-body force.
