DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NMTP2022/9/"
 >New approach to continuous spin models in two and three dimensions</a>\nb
 y Raghav Jha (Perimeter Institute) as part of Numerical Methods in Theoret
 ical Physics\n\n\nAbstract\nWe apply tensor network methods to study the f
 amous phase transition in the two-dimensional $O(2)$ model and a generaliz
 ed version of this  model that admits half-integer vortices in addition to
  the standard integer ones. We then consider the same model in three dimen
 sions and carry out  the first tensor study and locate the continuous phas
 e transition. Furthermore\, we introduce finite chemical potential and exp
 lore the Silver Blaze  phenomenon by computing the particle number density
 . While the addition of chemical potential leads to a non-real action and 
 is not suited for the  standard Monte Carlo\, it is straightforward to stu
 dy using tensors and presents itself as a strong contender over other nume
 rical methods.\n
