Jani Kastikainen

Jani Kastikainen is a Postdoctoral Researcher at the Institute for Theoretical Physics and Astrophysics, University of Würzburg, Germany. His research focuses on holographic dualities, quantum field theory, and gravity. He earned his B.Sc. and M.Sc. from the University of Helsinki (2013–2018), followed by a Ph.D. in Cotutelle from Université Paris Cité and the University of Helsinki (2019–2023).

Research Interests: Jani specializes in the AdS/CFT correspondence, two-dimensional conformal field theory (CFT), boundaries/defects in quantum field theory and gravity, higher-curvature theories of classical gravity, and classical and quantum aspects of gravity. His work bridges high-energy physics with quantum information theory, exploring entanglement and complexity in holographic systems.

Publications Overview: His recent publications (2025–2020) emphasize holography, quantum field theory in curved space-time, entanglement entropy, and boundary conformal field theories. Key subfields include Rényi entropy, corner terms in gravity, and applications of quantum hypothesis testing to many-body systems.

Collaborations: Jani is affiliated with the Würzburg Seminar on Quantum Field Theory and Gravity and has worked on projects involving branes, ABJM theory, and non-equilibrium CFTs.
