Clément Delcamp

Clément Delcamp is a CNRS Researcher in Physics at the Institut des Hautes Études Scientifiques (IHES), a position he has held since February 2025. Previously, he served as a Junior Professor of Physics at IHES from October 2023. His research bridges condensed matter theory, algebraic topology, and quantum field theory, focusing on symmetry, duality, and topological phases in quantum lattice models. He translates abstract category theory into physical frameworks using tensor networks.

His educational background includes undergraduate studies in France, an MSc in Quantum Fields and Fundamental Forces from Imperial College London (2013–2018, supported by a Walter-Zellidja fellowship), and a PhD from the Perimeter Institute for Theoretical Physics and the University of Waterloo (2018).

Delcamp investigates algebraic structures underlying quantum lattice many-body systems, leveraging tensor networks to develop classifying schemes and construct novel physical models. His work addresses how generalized symmetries and dualities manifest in systems ranging from (1+1)d to (3+1)d, with implications for quantum simulation and phase classification. Recent efforts include revisiting real-space renormalization group flows and formalizing the SymTFT proposal on lattices.

His publications reveal a trajectory from foundational work on string-like excitations and ϕ4 theory to cutting-edge explorations of non-abelian dualities and entanglement in the generalized Landau paradigm. Key themes include topological field theory applications, categorical symmetries, and tensor network methodologies across dimensions, emphasizing connections between mathematical structures and physical phenomena.

Award highlights include:

• Walter-Zellidja fellowship for graduate studies
• FWO Postdoctoral Fellowship from the Research Foundation – Flanders (2022)

Delcamp has held postdoctoral positions at the Max Planck Institute of Quantum Optics (Munich, 2018–2021) and the Max Planck Institute for the Physics of Complex Systems (Dresden, 2021–2022), followed by a postdoc at Ghent University (2022–2023). He actively recruits postdocs for theoretical physics research at IHES and collaborates internationally on topics including topological order and symmetry classification. His work integrates seminars, lectures, and workshops to advance lattice-based approaches to quantum phases.

He operates within IHES's theoretical physics group, leading projects that connect category theory with quantum many-body systems. Current initiatives involve developing tensor network frameworks for duality circuits and exploring electromagnetic duality in higher-dimensional topological models, supported by institutional resources and collaborative networks.
