High Energy Theory Group Meeting: TTbar deformation and long-range spin chains

Zoom: https://zoom.us/j/94391846242

Abstract: 

TTbar and more general solvable irrelevant deformations have been studied for relativistic quantum field theories. In this talk, I introduce a TTbar like deformation for quantum integrable spin chains and discuss some of its properties. Interestingly, such deformations for quantum spin chains was first proposed a decade ago in the context of integrability in \mathcal{N}=4 Super-Yang-Mills theory from rather different motivations.
