Weak coupling many-polaron description of ultracold bosonic impurities in a condensate

The weak coupling many-polaron formalism is applied to ultracold bosonic impurities in a Bose-Einstein condensate. This formalism allows calculating the ground state and response properties. We apply this to calculate both the inertial and spectral effective masses of the impurities and the response...

Description
Summary:The weak coupling many-polaron formalism is applied to ultracold bosonic impurities in a Bose-Einstein condensate. This formalism allows calculating the ground state and response properties. We apply this to calculate both the inertial and spectral effective masses of the impurities and the response of the system to Bragg scattering.
