DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Kadanoff/28/
 ">Dynamical hard rods and TTbar deformation</a>\nby Yunfeng Jiang (CERN) a
 s part of Kadanoff seminars\n\n\nAbstract\nIn this talk\, I will show that
  TTbar and a family of more general solvable bilinear deformations have th
 e effect of deforming point particles into hard rods with finite size. Thi
 s can be seen most easily for non-relativistic systems where the number of
  excitations is conserved. I will discuss this picture from two different 
 perspectives. In the first part\, I will discuss TTbar deformation of a co
 ncrete model\, which is the 1d Bose gas. In the second part\, I will provi
 de a 2d gravity interpretation for the TTbar deformation of generic non-re
 lativistic QFTs in the framework of Newton-Cartan geometry. Finally\, I wi
 ll discuss the physical implications of the hard rod picture.\n
