Ultracold ²³Na⁶Li molecules in the triplet ground state
… a two-photon stimulated Raman adiabatic passage (STIRAP) technique, forming 3 x 10⁴ molecules at a density of 5 x 10¹⁰ cm⁻³ and temperature of 3 [mu]K. The molecules are long-lived with a measured lifetime of 5 seconds, which highlights their fermionic nature and low universal inelastic loss rate. …

Dinamica effettiva di sistemi quantistici driven chiusi e aperti
… inspired by stimulated Raman adiabatic passage (STIRAP) since we aim to use the mode as a virtual quantum bus. This allows to suppress leakage from the computational subspace due to the dynamical Casimir effect. We find that renormalized terms in the low-energy Hamiltonian degrade the fidelity of …
