Boson-Gutzwiller Quantum liquids on a lattice
Daniel Pérez-Cruz, Manuel Valiente
We consider one-dimensional, interacting spinless bosons on a tight-binding lattice described by the Bose-Hubbard model. Besides attractive on-site two-body interactions, we includ…

Exactly Solvable Models of Interacting Chiral Bosons and Fermions on a Lattice
Manuel Valiente
We consider one-dimensional theories of chiral fermions and bosons on a lattice, which arise as edge states of two-dimensional topological matter breaking time-reversal invariance.…
