Magnetic resonance spectroscopy and characterization of magnetic phases for spinor Bose-Einstein condensates
arXiv:1212.0482 · doi:10.1103/PhysRevA.87.061604
Abstract
The response of spinor Bose-Einstein condensates to dynamical modulation of magnetic fields is discussed with linear response theory. As an experimentally measurable quantity, the energy absorption rate (EAR) is considered, and the response function is found to access quadratic spin correlations which come from the perturbation of the quadratic Zeeman term. By applying our formalism to spin-1 condensates, we demonstrate that the EAR spectrum as a function of the modulation frequency is able to characterize the different magnetically ordered phases.
