Non-perturbative quantum field theory: An introduction to Hamiltonian truncation

Kamran Salehi-Vaziri, Physics PhD Student, EPFL

Most interesting quantum field theories cannot be solved perturbatively. Hamiltonian truncation is a promising method to explore non-perturbative renormalisation group flows. In this crash course, we review the basic ideas of Hamiltonian truncation techniques by solving a simple example of quantum mechanical system and study more recent works.
