Proposal of quantum arrival-time measurement with a Bose-Einstein condensate
Pascal Naidon, Lucas Happ, Denis Boiron
This work shows how a Bose-Einstein condensate of ultracold atoms could be used to address a long-standing question in quantum theory: how much time does it take for a particle to…
From three-body resonances to bound states in a continuum: pole trajectories
Lucas Happ
We investigate the formation of three-body bound states in the continuum by tracing pole trajectories in the complex energy plane under variation of system parameters. Using a one-…
FewBodyToolkit.jl: a Julia package for solving quantum few-body problems
Lucas Happ
Few-body physics explores quantum systems of a small number of particles, bridging the gap between single-particle and many-body regimes. To provide an accessible tool for such stu…
Mass Ratio Dependence of Three-Body Resonance Lifetimes in 1D and 3D
Lucas Happ, Pascal Naidon, Emiko Hiyama
We present a theoretical study of resonance lifetimes in a two-component three-body system, specifically examining the decay of three-body resonances into a deep dimer and an unbou…
