Effects of atom losses on a one-dimensional lattice gas of hard-core bosons

F Riggio, L Rosso, D Karevski, J Dubail - Physical Review A, 2024 - APS
Atom losses occur naturally during cold atoms experiments. Since this phenomenon is
unavoidable, it is important to understand its effect on the remaining atoms. Here we …

gas subject to weak two-body losses. Our approach highlights the crucial role played by spin …

Strong spin-exchange recombination of three weakly interacting atoms

JL Li, T Secker, PMA Mestrom, S Kokkelmans - Physical Review Research, 2022 - APS
Quantifying the nonuniversal three-body losses in ultracold atomic gases has been a long-
standing problem. We go beyond earlier approaches to solve this problem by using a model …
