Theoretical physics
Andrzej Czarnecki
I am a professor of theoretical physics at the University of Alberta. My group studies quantum field theory, precision tests of fundamental interactions, and the properties and decays of bound particles.
I also work on questions in relativity and classical physics, often starting from simple systems that reveal a wider principle.
Research
Precision and fundamental interactions
Radiative corrections connect quantum field theory with precision measurements. My work includes lepton magnetic moments, neutron decay, and heavy-quark decays.
Bound particles and antimatter
Muonic atoms, positronium, and related systems let us study how binding changes a particle’s properties and decay. We use analytic calculations and numerical methods.
Relativity and classical physics
Recent work addresses spin and gravity, Thomas precession, pendulums in curved spacetime, satellite orbits, and shock waves.
