Bethe Colloquium by Gabriela Barenboim

December 2018
Gabriela Barenboim

The next Bethe Colloquium is scheduled for Thursday, 13th December, 2018, (4:15 pm) in Hörsaal I.

  • Gabriela Barenboim (Valencia)
  • A nu hope
  • Hörsaal I, Physikalisches Institut

Abstract: Massive neutrinos who were the last addition to the Standard Model, and arguably the first piece of evidence of the physics that hides behind it, can become an ideal tool to test the way we understand and describe Nature: local relativistic quantum field theory. I will show that used as tools neutrinos have the potential not only to chalenge the building we live in (SM), but also threaten the construction system. A fact that should not be underestimated.

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.
