Jens Oluf Andersen

Jens Oluf Andersen is a Professor in the Department of Physics at the Norwegian University of Science and Technology (NTNU). His research focuses on quantum chromodynamics (QCD) at finite temperature/density, cold Bose/Fermi gases, renormalization group methods, and effective field theories. He has made significant contributions to understanding phase diagrams in dense quark matter and the interplay between magnetic fields and QCD dynamics.

• Education & Affiliations: Physics at NTNU, leading the theoretical high-energy physics group.

His research interests span:
- QCD phase transitions and critical phenomena
- Chiral symmetry restoration in dense matter
- Magnetic catalysis and inverse magnetic catalysis effects
- Bose-Einstein condensation in QCD contexts
- Effective field theory approaches for strongly interacting systems

Recent work highlights the role of chiral perturbation theory in describing QCD at finite isospin density and the interplay between color superconductivity and thermodynamic properties. His 2025 papers explore chiral dynamics in QCD and its connection to Bose-Einstein condensation.

Key collaborations include studies with Prabal Adhikari on isospin-dependent QCD and with Martin Kjøllesdal Johnsrud on magnetic field effects. His 2022 work analyzed the electroweak phase transition in two-Higgs models using nonperturbative methods.
