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…
Vortex bound states in dimerized -flux optical lattices: characterization, state preparation and current measurement
Andrei A. Stepanenko, Marco Di Liberto
Lattice models display bound states for repulsive interactions that smoothly connect to high-energy two-particle states of doubly occupied sites, namely doublons, for strong onsite…
Strongly interacting photons in 2D waveguide QED
Matija TeÄer, Marco Di Liberto, Pietro Silvi +3
One dimensional confinement in waveguide Quantum Electrodynamics (QED) plays a crucial role to enhance light-matter interactions and to induce a strong quantum nonlinear optical re…
