Recent advancements in Separation of Variables for higher rank
Paul Ryan
(Trinity College Dublin)
Abstract:
"I will review recent advancements in the development of the Separation
of Variables (SoV) program for rational higher rank spin chains,
motivated by the recent appearance of SoV-type structures in AdS/CFT. I
will discuss the main approaches for constructing a separated variable
basis which include diagonalising the B-operator and the action of fused
transfer matricies on a suitable vacuum state. I will explain how these
approaches are linked and demonstrate how they can be unified into a
single framework governed by Yangian representation theory. The outcome
is that for any finite-dimensional su(n) spin chain the wave functions
(Bethe vectors) factorise into an ascending product of Slater
determinants in Baxter Q-functions, allowing us to immediately link this
operatorial construction of states with the recently developed
functional approach of computing scalar products and form factors."
NOTE: this will be an online seminar using Zoom. To participate please fill the registration form on integrability-london.weebly.com.
