Phases of interacting bosons in a hybrid Harper-Hofstadter system with a synthetic dimension of harmonic trap states
David G. Reid, Holly A. J. Middleton-Spencer, Grazia Salerno +2
Synthetic dimensions are a powerful tool for engineering desired quantum systems, based on coupling together sets of states and reinterpreting these as lattice sites along an artif…
Topological Chiral Edge States in a Synthetic Dimension of Atomic Trap States
David G. Reid, Christopher Oliver, Patrick Regan +6
A key hallmark of quantum Hall physics is the existence of topological chiral states at the system boundary. Signatures of these edge states have been experimentally observed in co…
High topological charge lasing in quasicrystals
Kristian Arjas, Jani M. Taskinen, Rebecca Heilmann +2
Photonic modes exhibiting a polarization winding akin to a vortex possess an integer topological charge. Lasing with topological charge 1 or 2 can be realized in periodic lattices…
All-optical switching at the two-photon limit with interference-localized states
Ville A. J. Pyykkönen, Grazia Salerno, Jaakko Kähärä +1
We propose a single-photon-by-single-photon all-optical switch concept based on interference-localized states on lattices and their delocalization by interaction. In its 'open' ope…
Drude weight and the many-body quantum metric in one-dimensional Bose systems
Grazia Salerno, Tomoki Ozawa, Päivi Törmä
We study the effect of quantum geometry on the many-body ground state of one-dimensional interacting bosonic systems. We find that the Drude weight is given by the sum of the kinet…
Supefluidity of flat band Bose-Einstein condensates revisited
Aleksi Julku, Grazia Salerno, Päivi Törmä
We consider the superfluid weight, speed of sound and excitation fraction of a flat band Bose-Einstein condensate (BEC) within multiband Bogoliubov theory. The superfluid weight is…
Loss-driven topological transitions in lasing
Grazia Salerno, Rebecca Heilmann, Kristian Arjas +3
We experimentally observe lasing in a hexamer plasmonic lattice and find that when tuning the scale of the unit cell, the polarization winding of the emission changes. By a theoret…
Bloch Oscillations Along a Synthetic Dimension of Atomic Trap States
Christopher Oliver, Aaron Smith, Thomas Easton +5
Synthetic dimensions provide a powerful approach for simulating condensed matter physics in cold atoms and photonics, whereby a set of discrete degrees of freedom are coupled toget…
Direct observation of photonic Landau levels and helical edge states in strained honeycomb lattices
O. Jamadi, E. Rozas, G. Salerno +9
We report the realization of a synthetic magnetic field for photons and polaritons in a honeycomb lattice of coupled semiconductor micropillars. A strong synthetic field is induced…
Floquet-engineering of nodal rings and nodal spheres and their characterization using the quantum metric
Grazia Salerno, Nathan Goldman, Giandomenico Palumbo
Semimetals exhibiting nodal lines or nodal surfaces represent a novel class of topological states of matter. While conventional Weyl semimetals exhibit momentum-space Dirac monopol…
Interaction-induced lattices for bound states: Designing flat bands, quantized pumps and higher-order topological insulators for doublons
Grazia Salerno, Giandomenico Palumbo, Nathan Goldman +1
Bound states of two interacting particles moving on a lattice can exhibit remarkable features that are not captured by the underlying single-particle picture. Inspired by this phen…
The quantized Hall conductance of a single atomic wire: A proposal based on synthetic dimensions
G. Salerno, H. M. Price, M. Lebrat +5
We propose a method by which the quantization of the Hall conductance can be directly measured in the transport of a one-dimensional atomic gas. Our approach builds on two main ing…
Topological two-body bound states in the interacting Haldane model
Grazia Salerno, Marco Di Liberto, Chiara Menotti +1
We study the topological properties of the two-body bound states in an interacting Haldane model as a function of interparticle interactions. In particular, we identify topological…
Propagating edge states in strained honeycomb lattices
Grazia Salerno, Tomoki Ozawa, Hannah M. Price +1
We investigate the helically-propagating edge states associated with pseudo-Landau levels in strained honeycomb lattices. We exploit chiral symmetry to derive a general criterion f…
Spin-orbit coupling in a hexagonal ring of pendula
Grazia Salerno, Alice Berardo, Tomoki Ozawa +4
We consider the mechanical motion of a system of six macroscopic pendula which are connected with springs and arranged in a hexagonal geometry. When the springs are pre-tensioned,…
Floquet topological system based on frequency-modulated classical coupled harmonic oscillators
Grazia Salerno, Tomoki Ozawa, Hannah M. Price +1
We theoretically propose how to observe topological effects in a generic classical system of coupled harmonic oscillators, such as classical pendula or lumped-element electric circ…
How to directly observe Landau levels in driven-dissipative strained honeycomb lattices
Grazia Salerno, Tomoki Ozawa, Hannah M. Price +1
We study the driven-dissipative steady-state of a coherently-driven Bose field in a honeycomb lattice geometry. In the presence of a suitable spatial modulation of the hopping ampl…
Dynamical decoupling and dynamical isolation in temporally modulated coupled pendulums
Grazia Salerno, Iacopo Carusotto
We theoretically study the dynamics of a pair of coupled pendulums subject to a periodic temporal modulation of their oscillation frequency. Inspired from analogous developments in…
