DESCRIPTION:Speaker: Khachatur Nazaryan\nhosted by Maksym Serbyn\nAbstract:
  We uncover a new superconducting state with partial spin polarization ind
 uced by a magnetic field. This state\, which we call "magnonic superconduc
 tor"\, lacks a conventional pairing order parameter\, but is characterized
  instead by a composite order parameter that represents the binding of ele
 ctron pairs and magnons. We rigorously demonstrate the existence of magnon
 ic superconductivity with high transition temperature in one- and two-dime
 nsional Hubbard models with repulsive interaction. We further show that ma
 gnonic Cooper pairs can attract to form higher-charge bound states\, which
  can give rise to charge-6e superconductivity.
