Weakly-interacting Bose-Bose mixtures from the functional renormalisation group
Felipe Isaule, Ivan Morera
We provide a detailed presentation of the functional renormalisation group (FRG) approach for weakly-interacting Bose-Bose mixtures, including a complete discussion on the RG equat…
Renormalization group study of Bose polarons
Felipe Isaule, Ivan Morera, Pietro Massignan +1
We study the properties of a single impurity in a dilute Bose gas, a Bose polaron, using the functional renormalization group. We use an ansatz for the effective action motivated b…
Functional renormalization for repulsive Bose-Bose mixtures at zero temperature
Felipe Isaule, Ivan Morera, Artur Polls +1
We study weakly-repulsive Bose-Bose mixtures in two and three dimensions at zero temperature using the functional renormalization group (FRG). We examine the RG flows and the role…
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…
