Advanced lattice field theories

Felipe Attanasio, Jan Martin Pawlowski summer term 2022

Lectures: Tuesday 09:15-11:00, Phil 12 R 106 [LSF]

External webpage lecture course



Prerequisites: Lattice field theory



Content of lecture series

This lecture course is a continuation of the “Lattice Field Theory” course, given in the winter semester of 2021/2022. The main idea of this course is to have a survey of modern, but accessible, methods used in lattice field theory. This will be done with concentrating on specific cases, whose implementation will be discussed in the “Application” lectures.

    Outline

  • Review of lattice QCD, and where modern methods are needed

  • Hybrid Monte Carlo

  • Matrix exponentials

  • Application I: finding the thermal transition in SU(3) Yang-Mills

  • Solvers I: CG and even-odd preconditioning

  • Solvers II: Mixed precision CG

  • Application II: Phase transitions on the 1+1d Yukawa model

  • Parallelisation I: splitting the lattice into sub-lattices

  • Parallelisation II: basics of parallel programming

  • Parallelisation III: parallel lattice simulations

  • Application III: Looking for volume scaling of the susceptibility

  • Considerations on memory access and cache locality (tentative topic)
