Standardized test of many-body coherence in gate-based quantum platforms
Yi Teng, Orazio Scarlatella, Shiyu Zhou +3
Quantum coherence is a crucial resource in achieving quantum advantage over classical information processing, and more generally developing new quantum technologies. While its effe…
How Subradiance Enables Nonlinearity in Weakly Driven Quantum Arrays
Orazio Scarlatella, Nigel R. Cooper
Harnessing the nonlinear response of a medium is essential for applications including frequency conversion and light amplification, as well as for the generation of quantum many-bo…
Fate of the Mollow triplet in strongly-coupled atomic arrays
Orazio Scarlatella, Nigel R. Cooper
Subwavelength arrays of quantum two-level emitters have emerged as an interesting platform displaying prominent collective effects that can be harnessed for applications. Here we s…
Deep Subwavelength Topological Edge State in a Hyperbolic Medium
Lorenzo Orsini, Hanan Herzig Sheinfux, Yandong Li +9
Topological nanophotonics presents the potential for cutting-edge photonic systems, with a core aim revolving around the emergence of topological edge states. These states are prim…
On the stability of dissipatively-prepared Mott insulators of photons
Orazio Scarlatella, Aashish A. Clerk, Marco Schirò
Reservoir engineering is a powerful approach for using controlled driven-dissipative dynamics to prepare target quantum states and phases. In this work, we study a paradigmatic mod…
Dynamics Near a Photonic Band-Edge: Strong Coupling Effects Beyond Rotating-Wave Approximation
Matthieu Vanhoecke, Orazio Scarlatella, Marco Schirò
We study the dynamics of a quantum emitter coupled to a two-dimensional photonic crystal featuring a finite bandwidth with sharp edges and a Van-Hove singularity. We study the effe…
Self-consistent dynamical maps for open quantum systems
Orazio Scarlatella, Marco Schirò
In several cases, open quantum systems can be successfully described using master equations relying on Born-Markov approximations, but going beyond these approaches has become ofte…
Dynamical Mean-Field Theory for Markovian Open Quantum Many-Body Systems
Orazio Scarlatella, Aashish A. Clerk, Rosario Fazio +1
Open quantum many body systems describe a number of experimental platforms relevant for quantum simulations, ranging from arrays of superconducting circuits to ultracold atoms in o…
Quantum Impurity Models coupled to Markovian and Non Markovian Baths
Orazio Scarlatella, Marco Schirò
We develop a method to study quantum impurity models, small interacting quantum systems linearly coupled to an environment, in presence of an additional Markovian quantum bath, wit…
Spectral functions and negative density of states of a driven-dissipative nonlinear quantum resonator
Orazio Scarlatella, Aashish A. Clerk, Marco Schirò
We study the spectral properties of Markovian driven-dissipative quantum systems, focusing on the nonlinear quantum van der Pol oscillator as a paradigmatic example. We discuss a g…
Emergent Finite Frequency Criticality of Driven-Dissipative Correlated Lattice Bosons
Orazio Scarlatella, Rosario Fazio, Marco Schiró
Critical points and phase transitions are characterized by diverging susceptibilities, reflecting the tendency of the system toward spontaneous symmetry breaking. Equilibrium stati…
Dissipation-Induced Superradiance in a Non-Markovian Open Dicke Model
Orazio Scarlatella, Marco Schiró
We consider the Dicke model, describing an ensemble of quantum spins interacting with a cavity field, and study how the coupling to a non-Markovian environment with power-law s…
