Nanofibre-based trap for Rb$_2$ molecule

Quantum Physics 2025-04-15 v1

Abstract

We describe a theoretical proposal of a nanofibre-based trap for a Rb2_2 molecule prepared in the metastable state (1)3Σu+(1)^3\Sigma^+_u. The trapping potential results from the combination of a travelling and a standing-wave fields, both carried by the fundamental guided mode HE11_{11} of the fibre. We show that, with an experimentally realistic choice of laser frequencies and powers, one can implement a 200\approx 200 μ\muK-deep well at 140\approx 140 nm from the fibre surface accomodating for 500\approx 500 translational molecular states.
