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…
Universal dimerized quantum droplets in a one-dimensional lattice
Ivan Morera, Grigori E. Astrakharchik, Artur Polls +1
The ground-state properties of two-component bosonic mixtures in a one-dimensional optical lattice are studied both from few- and many-body perspectives. We rely directly on a micr…
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…
Entanglement entropy in low-energy field theories at finite chemical potential
Ivan Morera, Irénée Frérot, Artur Polls +1
We investigate the leading area-law contribution to entanglement entropy in a system described by a general Lagrangian with O(2) symmetry containing first- and second-order time de…
Entanglement structure of a quantum simulator: the two-component Bose-Hubbard model
Ivan Morera, Artur Polls, Bruno Juliá-Díaz
We consider a quantum simulator of the Heisenberg chain with ferromagnetic interactions based on the two-component 1D Bose-Hubbard model at filling equal to two in the strong coupl…
