Boundary-induced geometrical frustration in a square Rydberg-atom lattice
Marco Rigobello, Luka Pavešić, Daniel Jaschke +4
We study geometric defects in square-lattice Rydberg-atom arrays induced by lattice-size parity in the striated density-wave phase. While odd-sized lattices select a single striate…
Phase and Photon Number Dependent NOON State Localization in Flat Band Lattices
Rishav Hui, Trideb Shit, Marco Di Liberto +2
Flat-band lattices supporting compact localized states provide a versatile platform for exploring unconventional transport phenomena in photonic, ultracold atomic, electronic, and…
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 -flux…

Trideb Shit, Rishav Hui, Marco Di Liberto +2
We study Hanbury Brown-Twiss spatial intensity correlations in femtosecond laser-fabricated photonic Su-Schrieffer-Heeger lattices using coherent input states with tunable phases.…
Strongly interacting photons in 2D waveguide QED
Matija Tečer, 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…

This work explores the possibility of creating and controlling unconventional nonlinearities by periodic driving, in a broad class of systems described by the nonlinear Schrödinger…
Quantized valley Hall response from local bulk density variations
Maxime Jamotte, Lucila Peralta Gavensky, Cristiane Morais Smith +2
The application of a mechanical strain to a 2D material can create pseudo-magnetic fields and lead to a quantized valley Hall effect. However, measuring valley-resolved effects rem…

We develop a toolbox for manipulating arrays of Rydberg atoms prepared in high-dimensional hydrogen-like manifolds in the regime of linear Stark and Zeeman effect. We exploit the S…
Floquet engineering of optical nonlinearities: a quantum many-body approach
Nathan Goldman
Subjecting a physical system to a time-periodic drive can substantially modify its properties and applications. This Floquet-engineering approach has been extensively applied to a…

Ultracold atoms loaded into higher Bloch bands provide an elegant setting for realizing many-body quantum states that spontaneously break time-reversal symmetry through the formati…
Topological phonons in arrays of ultracold dipolar particles
Marco Di Liberto, Andreas Kruckenhauser, Peter Zoller +1
The notion of topology in physical systems is associated with the existence of a nonlocal ordering that is insensitive to a large class of perturbations. This brings robustness to…

Maxime Jamotte, Nathan Goldman, Marco Di Liberto
Applying time-periodic modulations is routinely used to control and design synthetic matter in quantum-engineered settings. In lattice systems, this approach is explored to enginee…
