Quantum oscillations of the quasiparticle lifetime in a metal

Nature, Published online: 02 August 2023; doi:10.1038/s41586-023-06330-yQuantum oscillations in the three-dimensional topological semimetal CoSi are reported, where selected oscillation frequencies have no corresponding extremal Fermi surface cross-sections, representing instead oscillations of the quasiparticle lifetime. #press
