Scattering and induced false vacuum decay in the two-dimensional quantum Ising model
Luka PaveÅ¡iÄ, Marco Di Liberto, Simone Montangero
We study scattering in the quantum Ising model in two dimensions. In the ordered phase, the spectrum contains a ladder of bound states and intertwined scattering resonances, which…

Fate of chiral order and impurity self-pinning in flat bands with local symmetry
Maxime Burgher, Marco Di Liberto, Nathan Goldman +1
Interacting bosons on a single plaquette threaded by a -flux can spontaneously break time-reversal symmetry, resulting in a chiral loop current. Connecting such bosonic -fl…
