Mathias Heymann is a theoretical physicist and computational scientist noted for work on condensed matter physics, ultracold atoms, quantum many-body systems, and tensor network methods. He has contributed to studies that intersect with experimental platforms such as optical lattices, quantum simulators, and cold-atom experiments, collaborating with researchers associated with institutions like École Normale Supérieure, Max Planck Institutes, and CNRS laboratories. His work interfaces with topics explored at conferences and schools including the International Conference on Quantum Simulation, the Gordon Research Conferences, and workshops at CERN.

Early life and education

Born and raised in Germany, Heymann pursued undergraduate and graduate studies that led him through research environments associated with universities such as the Technical University of Munich, Ludwig Maximilian University of Munich, Humboldt University of Berlin, and international centers including École Polytechnique and University of Cambridge. During his doctoral training he interacted with research groups at the Max Planck Institute for Quantum Optics, the Institut d'Optique, and collaborations involving researchers from Harvard University, Massachusetts Institute of Technology, and Princeton University. His graduate advisors and collaborators have included scientists from Imperial College London, University of Oxford, and Stanford University, linking him to broader networks including the APS, IOP, and EPS.

Career

Heymann's career spans postdoctoral appointments and faculty roles connected to institutions such as CNRS laboratories, École Normale Supérieure, University of Geneva, and research centers at ETH Zurich. He has held positions in research groups that collaborate with experimental teams at MIT-Harvard centers, Caltech, and the Max Planck Society. His professional trajectory includes participation in EU-funded projects, ERC grants, Marie Skłodowska-Curie networks, and partnerships with industrial research units at IBM Research, Google Quantum AI, and Microsoft Research. Heymann has served on organizing committees for meetings like the International Conference on Quantum Simulation, DAMOP, and the Les Houches Summer School, and has been involved with editorial boards of journals published by Nature Research, American Physical Society, and IOP Publishing.

Research and contributions

Heymann's research contributions focus on quantum many-body physics, tensor network algorithms, density matrix renormalization group (DMRG), matrix product states (MPS), projected entangled pair states (PEPS), and time-dependent variational principles (TDVP). He has studied strongly correlated systems relevant to Hubbard models, Bose–Hubbard models, Fermi–Hubbard models, Kondo physics, and spin models such as Heisenberg chains and Kitaev materials. His computational work connects to topics in quantum information theory studied by groups at Perimeter Institute, Institute for Quantum Computing, and NIST, and to numerical frameworks like ITensor, TeNPy, and ALPS. Heymann has developed methods applied to simulation of nonequilibrium dynamics, thermalization, many-body localization, quantum quenches, and transport phenomena in low-dimensional systems examined at laboratories such as LPTMS, CEA Saclay, and JILA. Collaborations have tied his work to experimental platforms including optical lattices, Rydberg atom arrays, trapped-ion chains, superconducting qubits, and solid-state platforms investigated by groups at Columbia University, Yale University, and University of Chicago.

Notable publications

Heymann has authored and coauthored papers in journals published by Nature Physics, Physical Review Letters, Physical Review B, Science Advances, and New Journal of Physics. His publications address subjects such as entanglement growth after a quantum quench, finite-temperature algorithms for tensor networks, benchmarks of MPS and PEPS for two-dimensional Hubbard models, and methods for simulating dissipative dynamics in open quantum systems linked to Lindblad formalisms explored at institutions including Weizmann Institute, Technion, and University of Tokyo. He has contributed chapters to edited volumes and proceedings for workshops at Les Houches, KITP, and Aspen Center for Physics, and preprints circulated on arXiv impacting research groups at CNRS, MPI, and universities across Europe and North America.

Awards and recognition

Heymann's work has been recognized by honors from professional societies and funding agencies including European Research Council grants, German Research Foundation awards, Marie Skłodowska-Curie fellowships, and recognition at conferences such as the Gordon Research Conferences and DAMOP. He has been invited to give talks at institutions like the Perimeter Institute, Kavli Institute for Theoretical Physics, and Institut Henri Poincaré, and has received travel and young investigator awards connected to organizations such as the German Physical Society, Royal Society, and European Physical Society.
