Exciting the long-lived Higgs mode in superfluid Fermi gases with particle removal
Exciting the long-lived Higgs mode in superfluid Fermi gases with particle removal
Experimental evidence of the Higgs mode in strongly interacting superfluid Fermi gases had not been observed until recently [Behrle et al., Nat. Phys. 14, 781 (2018).]. Due to the coupling with other collective modes and quasiparticle excitations, generating stable Higgs-mode oscillations is challenging. We study how to excite long-lived Higgs-mode …
