Rate My Professor Joachim Brand

Brand’s research specializes in quantum physics, condensed matter physics, computational physics, nonlinear waves, and complex systems, with a focus on nonlinear wave phenomena such as solitons in Bose-Einstein condensates, strong correlations in Bose and Fermi quantum gases, superfluidity, and quantum simulations. His group develops software tools like Rimu.jl for quantum many-body systems and QiwiB for multi-configurational time-dependent Hartree for bosons. Key publications include Backert et al., 'Effective Theory for Strongly Attractive One-Dimensional Fermions' (Physical Review Letters, 2025); Major and Brand, 'Swallow-tail dispersions of moving solitons in a two-dimensional fermionic superfluid' (Physical Review A, 2024); Choudhury and Brand, 'Distributed vorticity model for vortex molecule dynamics' (Physical Review A, 2023); and earlier seminal works such as Muñoz Mateo and Brand, 'Chladni solitons and the onset of the snaking instability for dark solitons in confined superfluids' (Physical Review Letters, 2014) and Brand et al. on soliton-vortex collisions (Physical Review Letters, 2005). His research has over 3,300 citations across 136 publications. Brand has delivered public lectures, including on gravitational waves and the sounds of the universe.
