Bethe Colloquium by Gleb Arutyunov

January 2019
Gleb Arutyunov

The first Bethe Colloquium in 2019 will take place on Thursday, January 17th, 2019, (4:15 pm) in Hörsaal I.

  • Gleb Arutyunov (Hamburg University, II. Institute for Theoretical Physics)
  • R-matrix Quantization of the Ruijsenaars-Schneider Models
  • Hörsaal I, Physikalisches Institut

Abstract: I describe an algebraic scheme for quantizing the Ruijsenaars-Schneider models in the R-matrix formalism. It is based on a special parametrization of the cotangent bundle over GL(n,C). In new variables the standard symplectic structure is described by a classical (Frobenius) r-matrix and by a new dynamical \bar{r}-matrix. Quantizing these r-matrices, I will exhibit the quantum L-operator algebra and construct its particular representation corresponding to the Ruijsenaars-Schneider system. I will also indicate a couple of open problems.
