Guilherme Franzmann

Guilherme Franzmann is an Assistant Professor at Nordita (Nordic Institute for Theoretical Physics), hosted by Stockholm University, Sweden. His research spans theoretical physics with a primary focus on cosmological models derived from fundamental theories.

His research interests include:

• Cosmology
• String Theory
• Modified Gravity
• Theoretical Physics
• High-Energy Physics
• Astroparticle Physics

Analysis of his 15 most recent publications (2019-2024) reveals a concentrated effort in string cosmology, particularly exploring higher-order α′ corrections in string theory for early universe solutions. His work bridges quantum gravity and observational cosmology through frameworks like double field theory and T-duality, while also addressing foundational issues like the cosmological constant problem and dark matter unification via superfluid models. A notable non-technical contribution critiques academic publishing practices.

Guilherme operates within Nordita, a premier Nordic collaborative institute fostering advanced theoretical research across astrophysics, condensed matter, and high-energy physics through international workshops and long-term programs.
