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…
Quantum liquids and droplets with low-energy interactions in one dimension
Ivan Morera, Bruno Juliá-Díaz, Manuel Valiente
We consider interacting one-dimensional bosons in the universal low-energy regime. The interactions consist of a combination of attractive and repulsive parts that can stabilize qu…
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…
Supervised learning of few dirty bosons with variable particle number
Pere Mujal, Àlex Martínez Miguel, Artur Polls +2
We investigate the supervised machine learning of few interacting bosons in optical speckle disorder via artificial neural networks. The learning curve shows an approximately unive…
Static and dynamic properties of a few spin interacting fermions trapped in an harmonic potential
Abel Rojo-Francàs, Artur Polls, Bruno Juliá-Díaz
We provide a detailed study of the properties of a few interacting spin fermions trapped in a one-dimensional harmonic oscillator potential. The interaction is assumed to be…
Quantum droplets of bosonic mixtures in a one-dimensional optical lattice
Ivan Morera, Grigori E. Astrakharchik, Artur Polls +1
We demonstrate the existence of quantum droplets in two-component one-dimensional Bose-Hubbard chains. The droplets exist for any strength of repulsive intra-species interactions p…
