| 英文摘要 | We study supersymmetric (SUSY) responses to a photoassociation (PA) process in a mixture of Bose molecules b and Fermi atoms f which turn to mutual superpartners for a set of proper parameters. We consider the molecule b to be a bound state of the atom f and another Fermi atom F with different species. The b-f mixture and a free F atom gas are loaded in an optical lattice. The SUSY nature of the mixture can be signaled in the response to a photon-induced atom-molecule transition: While two new types of fermionic excitations, an individual b particle-f hole pair continuum and the Nambu-Goldstone-fermion-like (or "goldstino-like") collective mode, are concomitant for a generic b-f mixture, the former is completely suppressed in the SUSY b-f mixture and the zero-momentum mode of the latter approaches an exact eigenstate. This SUSY response can be detected by means of the spectroscopy method, for example, the PA spectrum which displays the molecular formation rate of Ff -> b. |
