Phase separation can be stronger than chaos
Andrea Richaud, Vittorio Penna
We investigate several dynamical regimes characterizing a bosonic binary mixture loaded in a ring trimer, with particular reference to the persistence of demixing. The degree of ph…
Static properties of two linearly coupled discrete circuits
Albert Escrivà, Andrea Richaud, Bruno Juliá-Díaz +1
Bosonic two-ring ladders constitute an important class of atomtronic circuits, where coherent current flows not only can offer a new insight into many-body physics, but also can pl…
The phase-separation mechanism of a binary mixture in a ring trimer
Vittorio Penna, Andrea Richaud
We show that, depending on the ratio between the inter- and the intra-species interactions, a binary mixture trapped in a three-well potential with periodic boundary conditions exh…
Residual entropy and critical behavior of two interacting boson species in a double well
Fabio Lingua, Andrea Richaud, Vittorio Penna
Motivated by the importance of entanglement and correlation indicators in the analysis of quantum systems, we study the equilibrium and the bipartite residual entropy in a two-spec…
