Lowenergy theorems in field theory
Lowenergy theorems facilitate calculations in quantum field theory.
In this project, you will verify this with concrete cases from particle physics.
The student will learn:
 Basic concepts from quantum field theory.
 Its application in practical calculations.
Requirements:
 Affinity to mathematics and theoretical physics.
Asymptotic expansions and the Gradient Flow
The gradient flow formalism has been suggested in 2010 to facilitate
practical calculations in Lattice QCD. It has proven to be accessible also
in perturbation theory and provides a promising link between the two
approaches to strong interactions. In this project, you are going to
develop means to calculate the resulting Feynman integrals in a systematic
way.
The student will learn:
 The general method of the gradient flow.
 Approaches to calculating nonstandard Feynman integrals.
Requirements:
 Affinity to mathematics and theoretical physics.
Feynman diagrams as a parlor game
Feynman diagrams provide a very algorithmic way to generate and represent
processes in particle physics. In this project, you will devise a
generalization of the parlor game Scrabble to Feynman diagrams.
The student will learn:
 The algorithmic structure of Feynman diagrams.
Requirements:
 Interest in Feynman diagrams.
 Affinity to computer programming.
The reality of virtual particles
Virtual particles are an essential component in the perturbative
theoretical description of particle physics. In this project, you will
study and compare various viewpoints on the virtual particle concept.
The student will learn:
 Basic concepts of quantum field theory.
 The critical assessment of interpretations of quantum physics.
Requirements:
 Interest in particle physics and the history and philosophy of physics.
Epidemiological models from a physicist's perspective
Metrics for the SARSCoV2 virus are about as pervasive as the virus itself.
Where do they come from, and how reliable and statistically significant are they?
The models used to estimate the impact of various measures are not too different
from various evolution models in physics. In this project, you are going to
study the most popular ones among them, and investigate the correlations between
the corresponding statistical uncertainties.
The student will learn
 to acquire expertise on a novel topic.
Requirements:
 Basic programming skills.
 Basic knowledge of statistics.
