Daniel Pajer

Daniel Pajer is a Research Fellow in the Mathematical Institute at the University of Oxford. His research interests include non-invertible symmetries in quantum field theory, with recent work focusing on gapless and gapped phases, symmetry-protected topological phases, and categorical Landau paradigms. Pajer has contributed to several publications, including studies on boundary symTFT, non-invertible symmetries in (2+1)d, and quantum corrections to BPS Wilson loops in superstring theory. He has also collaborated on research involving rainbow reflection and energy harvesting. Pajer's academic profile includes teaching roles in courses such as Electromagnetism and Renormalisation Group.

Daniel Pajer is a DPhil student at the University of Oxford, specializing in quantum field theory and symmetries. His research focuses on gapped and gapless phases of matter, particularly those involving non-invertible symmetries. He explores the classification of topological phases using categorical frameworks and investigates the role of symmetries in phase transitions. His work includes the development of Hasse diagrams for gapless symmetry-protected topological (SPT) and symmetry-breaking (SSB) phases, as well as the study of boundary symTFTs. Pajer's research also extends to quantum corrections in superstring theory with mixed flux, highlighting his interdisciplinary approach to theoretical physics.
