Quantum polarization spectroscopy of ultracold spinor gases.
We propose a method for the detection of ground state quantum phases of spinor gases through a series of two quantum nondemolition measurements performed by sending off-resonant, polarized light pulses through the gas. Signatures of various mean-field as well as strongly correlated phases of F=1 and F=2 spinor gases obtained by detecting quantum fluctuations and mean values of polarization of t...
متن کاملDynamics and thermodynamics in spinor quantum gases
We discuss magnetism in spinor quantum gases theoretically and experimentally with emphasis on temporal dynamics of the spinor order parameter in the presence of an external agnetic field. In a simple coupled Gross-Pitaevskii picture we observe a dramatic suppression of spin dynamics due to quadratic Zeeman ”dephasing”. In view of an inhomogeneous density profile of the trapped condensate we pr...
متن کاملResonant spin-changing collisions in spinor fermi gases.
The compensation of quadratic Zeeman effect and trap energy in high-spin fermions is shown to lead to resonances in the spin-changing collisions that are typically absent in spinor condensates and spin-1/2 fermions. We study these resonances in lattice fermions, showing that they permit the targeting of a particular spin-changing channel while suppressing the rest and the creation of magnetical...
متن کاملNon-linear phenomena in polar gases and quasi-relativistic spinor condensates
In this talk I will overview some of our recent results on non-linear phenomena in two different physical scenarios: polar gases and quantum gases in the presence of artificial electromagnetism. In the first part I will discuss novel phenomena in polar gases, including the peculiar nature of Faraday patterns in dipolar condensates, the formation of Schrdinger cats in three-well systems, and nov...
متن کاملMedical Imaging with Laser Polarized Noble Gases
The field of medical imaging with polarized rare gases, just five years old, has brought optical scientists together with medical researchers to perfect techniques and pursue new opportunities for biomedical research. This review, written for the likely reader of these volumes, aims to present the field from several perspectives. The historical perspective shows how applications of nuclear pola...
