Analysis of the singular band structure occurring in one-dimensional topological normal and superfluid fermionic systems: A pedagogical description
Marcello Calvanese Strinati, Giancarlo Calvanese Strinati
Topological properties of solid-state materials arise when crossings occur in their band-structure eigenvalues, which give rise to discontinuities in the associated Bloch-function…

Ising machine by dimensional collapse of nonlinear polarization oscillators
Salvatore Chiavazzo, Marcello Calvanese Strinati, Claudio Conti +1
Ising machines show promise as ultrafast hardware for optimizations encoded in Ising Hamiltonians but fall short in terms of success rate and performance scaling. Here, we propose…

Quantum hyperspins: Highly nonclassical collective behavior in quantum optical parametric oscillators
Marcello Calvanese Strinati, Claudio Conti
We report on the emergence of a highly non-classical collective behavior in quantum parametric oscillators, which we name quantum hyperspin, induced by a tailored nonlinear interac…
