Nonadiabatic production of spinor condensates with a QUIC trap

TL;DR

This paper develops a theoretical framework to understand how nonadiabatic Landau-Zener transitions in a QUIC trap can produce multi-component spinor condensates, linking system parameters to observable spin populations.

Contribution

Findings

Derived a formula for spin population distribution based on system parameters.

Provided insights into the mechanism of spinor condensate formation via nonadiabatic level crossings.

Linked theoretical predictions with experimental data on multi-component condensates.

Abstract

Motivated by the recent experimental observation of multi-component spinor condensates via a time-dependent quadrupole-Ioffe-configuration trap (QUIC trap), we provide a general framework for the investigation of nonadiabatic Landau-Zener dynamics of a hyperfine spin, e.g., from an atomic magnetic dipole moment coupled to a weak time-dependent magnetic (B-) field. The spin flipped population distribution, or the so-called Majorona formula is expressed in terms of system parameters and experimental observables; thus, provides much needed insight into the underlying mechanism for the production of spinor condensates due to nonadiabatic level crossings.
