Emergent cavity-QED dynamics along the edge of a photonic lattice

Enrico Di Benedetto, Xuejian Sun, Marcel A. Pinto +6

We investigate qubits coupled to the boundary of a two dimensional photonic lattice that supports dispersionless edge modes, unlike conventional edge modes that sustain propagating…

Quantum optics with giant atoms in a structured photonic bath

L. Leonforte, X. Sun, D. Valenti +4

We present a general framework to tackle quantum optics problems with giant atoms, i.e. quantum emitters each coupled {\it non-locally} to a structured photonic bath (typically a l…

Dressed emitters as impurities

Luca Leonforte, Davide Valenti, Bernardo Spagnolo +2

Dressed states forming when quantum emitters or atoms couple to a photonic bath underpin a number of phenomena and applications, in particular dispersive effective interactions occ…

Vacancy-like dressed states in topological waveguide QED

Luca Leonforte, Angelo Carollo, Francesco Ciccarello

We identify a class of dressed atom-photon states formingat the same energy of the atom at any coupling strength. As a hallmark, their photonic component is an eigenstate of the ba…

Haldane Model at finite temperature

Luca Leonforte, Davide Valenti, Bernardo Spagnolo +2

We consider the Haldane model, a 2D topological insulator whose phase is defined by the Chern number. We study its phases as temperature varies by means of the Uhlmann number, a fi…

On critical properties of Berry curvature in Kitaev honeycomb model

Francesco Bascone, Luca Leonforte, Davide Valenti +2

We analyse the Kitaev honeycomb model, by means of the Berry curvature with respect to Hamiltonian parameters. We concentrate on the ground-state vortex-free sector, which allows u…

Finite temperature geometric properties of the Kitaev honeycomb model

Francesco Bascone, Luca Leonforte, Bernardo Spagnolo +2

We study finite temperature topological phase transitions of the Kitaev's spin honeycomb model in the vortex-free sector with the use of the recently introduced mean Uhlmann curvat…

Uhlmann number in translational invariant systems

Luca Leonforte, Davide Valenti, Bernardo Spagnolo +1

We define the Uhlmann number as an extension of the Chern number, and we use this quantity to describe the topology of 2D translational invariant Fermionic systems at finite temper…
