  bibo_abstract:
  - "Magnets with isotropic easy-plane symmetry host Goldstone modes that can be leveraged
    for efficient\r\nspin transport. Here, we present a time-resolved optical polarimetry
    technique that allows us to detect and\r\ncharacterize such low-frequency modes,
    and use it to observe the Goldstone mode in the multi-Q broken helix\r\nphase
    of EuIn2As2. The strength of our technique comes from the ability to distinguish
    between nematic and\r\nmagnetization dynamics in order to yield information about
    the mode structure, in addition to its frequency. We\r\nfind that the nearly uniform
    spin precession characteristic of a Goldstone mode is realized only when a small\r\nmagnetic
    field is used to unpin the broken helix from local strain generated during crystal
    growth. In this regime,\r\nthe mode frequency scales linearly with the applied
    field due to the ground state C2z symmetry of the broken\r\nhelix. Our work shows
    how optical polarimetry can be used to study the Goldstone modes of complex magnets.@eng"
