Nicolas Regnault joined the Center for Computational Quantum Physics (CCQ) in 2024 as a Research Scientist. He is also a Centre National de la Recherche Scientifique (CNRS) research director at the École Normale Supérieure in Paris and a visiting researcher at Princeton University. He received his Ph.D. on integrable models for gravity in 2002 from the University of Paris Saclay. He then moved to condensed matter during his postdoctoral position at the École Normale Supérieure, getting hired by the Centre National de la Recherche Scientifique in 2003.
Nicolas’s expertise covers a variety of topics. Among them are the fractional quantum Hall physics and fractional Chern insulators, with a special focus on the numerical aspects using methods such as large scale exact diagonalizations (through his publicly available software DiagHam) and matrix product states. His interests also extend to topological phases of matter, leading the topological material database initiative, moiré materials, entanglement properties in many-body quantum states and out-of-equilibrium quantum systems.
