During this Student Seminar we are going to have two speakers who will give the following talks:
1st Talk – A homotopy transfer primer
Speaker: Maria Kallimani
Abstract:
“Perturbative field theories can be expressed in the language of homotopy algebras which encode their symmetries and kinematical data. In this framework, one can connect physically equivalent theories through Homotopy Transfer. In my talk, I will discuss how it works and show how to implement through it familiar processes, like integrating out degrees of freedom of fields.”
2nd Talk – Distillation Method in Lattice QCD
Speaker: Andres Stump
Abstract:
“Computing energies of bound hadronic states with four or more valence quarks such as tetraquarks and dibaryons remains a huge challenge in lattice QCD. The major difficulties are the inversion of the Dirac operator and the excited state contamination of the correlator. I present the distillation method which aims to solve these problems. It’s a quark smearing method that allows to fully compute the inverse of the Dirac operator on a subspace spanned by eigenvectors of the Laplace operator. Simultaneously, it reduces the contribution from excited states.”
The Zoom link will be distributed to RTG students via email and can be requested to Giuseppe Casale or Andres Stump.
