On the Kantor product
20170628

Speaker: Ivan Kaygorodov (Univ. Federal do ABC, Santo André, Brazil; Siberian State Aerospace Univ., Krasnoyarsk, Russia)

Kantor defined the conservative algebras as an generalization of Lie and Jordan algebras. There are many relations between conservative algebras and other nonassociative algebras. We will talk about some classical papers of Kantor and some new results obtained in some joint work with Yu. Volkov,...



A new signature of quantum phase transitions from the numerical range
20170710

Speaker: Stephan Weis (Université libre de Bruxelles, Belgium)

A quantum phase transition is a ground state phenomenon in an infinite lattice model with various defining key properties. We focus on two of them and point out their signatures in finite lattice models: Nonanalyticity of the ground state energy and strong variation of the entropy of inferred...
