Thermodynamics of Bose gases from functional renormalization with a hydrodynamic low-energy effective action
Felipe Isaule, Michael C. Birse, Niels R. Walet
The functional renormalization group for the effective action is used to construct an effective hydrodynamic description of weakly interacting Bose gases. We employ a scale-depende…
Application of the functional renormalization group to Bose gases: from linear to hydrodynamic fluctuations
Felipe Isaule, Michael C. Birse, Niels R. Walet
We study weakly interacting Bose gases using the functional renormalization group with a hydrodynamic effective action. We use a scale-dependent parametrization of the boson fields…
Convergence of a renormalization group approach to dimer-dimer scattering
Michael C. Birse, Boris Krippa, Niels R. Walet
We study the convergence of a functional renormalisation group technique by looking at the ratio between the fermion-fermion scattering length and the dimer-dimer scattering length…
Renormalization group, dimer-dimer scattering, and three-body forces
Boris Krippa, Niels R. Walet, Michael C. Birse
We study the ratio between the fermion-fermion scattering length and the dimer-dimer scattering length for systems of nonrelativistic fermions, using the same functional renormalis…
