New quantumness domains through generalized squeezed states
Francesco Raffa, Mario Rasetti, Marco Genovese
Current definitions of both squeezing operator and squeezed vacuum state are critically examined on the grounds of consistency with the underlying su(1,1) algebraic structure. Acco…
Where do bosons actually belong?
A Marzuoli, F A Raffa, M Rasetti
We explore a variety of reasons for considering su(1,1) instead of the customary h(1) as the natural unifying frame for characterizing boson systems. Resorting to the Lie-Hopf stru…
Peierls Distortion and Quantum Solitons
Chiara Marletto, Mario Rasetti
Peierls distortion and quantum solitons are two hallmarks of 1-dimensional condensed-matter systems. Here we propose a quantum model for a one-dimensional system of non-linearly in…
On Nonlinear Bosonic Coherent States
Marco Genovese, Francesco A. Raffa, Mario Rasetti
Nonlinear coherent states are an interesting resource for quantum technologies. Here we investigate some critical features of the single-boson nonlinear coherent states, which are…
Microscopic description of 2d topological phases, duality and 3d state sums
Zoltan Kadar, Annalisa Marzuoli, Mario Rasetti
Doubled topological phases introduced by Kitaev, Levin and Wen supported on two dimensional lattices are Hamiltonian versions of three dimensional topological quantum field theorie…
Braiding and entanglement in spin networks: a combinatorial approach to topological phases
Zoltan Kadar, Annalisa Marzuoli, Mario Rasetti
The spin network quantum simulator relies on the su(2) representation ring (or its q-deformed counterpart at q= root of unity) and its basic features naturally include (multipartit…
