Renormalization group flows for Wilson-Hubbard matter and the topological Hamiltonian
E. Tirrito, M. Rizzi, G. Sierra +2
Understanding the robustness of topological phases of matter in the presence of interactions poses a difficult challenge in modern condensed matter, showing interesting connections…
Topological Devil's staircase in atomic two-leg ladders
S. Barbarino, D. Rossini, M. Rizzi +3
We show that a hierarchy of topological phases in one dimension -- a topological Devil's staircase -- can emerge at fractional filling fractions in interacting systems, whose singl…
Gross-Neveu-Wilson model and correlated symmetry-protected topological phases
A. Bermudez, E. Tirrito, M. Rizzi +2
We show that a Wilson-type discretization of the Gross-Neveu model, a fermionic N-flavor quantum field theory displaying asymptotic freedom and chiral symmetry breaking, can serve…
The Rhombi-Chain Bose-Hubbard Model: geometric frustration and interactions
Christine Cartwright, Gabriele De Chiara, Matteo Rizzi
We explore the effects of geometric frustration within a one-dimensional Bose-Hubbard model using a chain of rhombi subject to a magnetic flux. The competition of tunnelling, self-…
Tan's contact scaling behaviour for trapped Lieb-Liniger bosons: from two to many
Matteo Rizzi, Christian Miniatura, Anna Minguzzi +1
We show that the contact parameter of N harmonically-trapped interacting 1D bosons at zero temperature can be analytically and accurately obtained by a simple rescaling of the exac…
