Excitation spectra and rank tomography of finite MPS tangent spaces
Otto T. P. Schmidt, Iacopo Carusotto
We formulate the matrix product state (MPS) tangent-space excitation construction for finite, non-uniform systems with open boundary conditions, using the smooth full-rank stratum…
Photon avalanche triggered by a single photon in a bistable nonlinear optical cavity
Asian Selvakumaran, Anna Minguzzi, Iacopo Carusotto +1
We theoretically investigate the response of a coherently-driven nonlinear optical cavity to an additional incident single photon. Using a quantum description of the nonlinear dyna…
Doppler-induced tunable and shape-preserving frequency conversion of microwave wave packets
Felix Ahrens, Enrico Bogoni, Renato Mezzena +7
In superconducting electronics, the ability to control the frequency of microwave wave packets is crucial for several applications, such as the operation of superconducting quantum…
From coherent to fermionized microwave photons in a superconducting transmission line
Alberto Tabarelli de Fatis, Stephanie Matern, Gianluca Rastelli +1
We investigate superconducting transmission lines as a novel platform for realizing a quantum fluid of microwave photons in a propagating geometry. We predict that the strong photo…
Dispersive detection of single microwave photons with quantum dots
Stephanie Matern, Alberto Biella, Pasquale Scarlino +2
Within a circuit quantum electrodynamics architecture, we theoretically investigate the detection of a single propagating microwave photon traveling through a resonant microwave ca…
Theory of quantum spin-Hall topological lasers
Alberto Muñoz de las Heras, Iacopo Carusotto
We theoretically investigate a quantum spin-Hall topological laser formed by an array of dielectric ring resonators endowed of saturable gain. The system preserves time-reversal sy…
Many-body theory of false vacuum decay in quantum spin chains
Christian Johansen, Alessio Recati, Iacopo Carusotto +1
In this work we theoretically investigate the false vacuum decay process in a ferromagnetic quantum spin-1/2 chain. We develop a many-body theory describing the nucleation and the…
Quantized Hall drift in a frequency-encoded photonic Chern insulator
Alexandre Chénier, Bosco d'Aligny, Félix Pellerin +4
The quantization of transport and its resilience to backscattering are key features for leveraging topological matter in applications that demand stringent noise mitigation, such a…
Synthetic-lattice Bloch wave dynamics in a single-mode microwave resonator
F. Ahrens, N. Crescini, A. Irace +8
Frequency-based synthetic dimensions are a promising avenue for expanding the dimensionality of photonic systems. In this work, we show how a tilted synthetic lattice is naturally…
Emerging supersolidity from a polariton condensate in a photonic crystal waveguide
Dimitrios Trypogeorgos, Antonio Gianfrate, Manuele Landini +10
A supersolid is a counter-intuitive phase of matter where its constituent particles are arranged into a crystalline structure, yet they are free to flow without friction. This requ…
Nonlinear Behavior of Josephson Traveling Wave Parametric Amplifiers
Claudio Guarcello, Felix Ahrens, Guerino Avallone +40
Recent advancements in quantum technologies and advanced detection experiments have underscored the pressing need for the detection of exceedingly weak signals within the microwave…
Development of KI-TWPAs for the DARTWARS project
Felix Ahrens, Elena Ferri, Guerino Avallone +40
Noise at the quantum limit over a broad bandwidth is a fundamental requirement for future cryogenic experiments for neutrino mass measurements, dark matter searches and Cosmic Micr…
Broadband parametric amplification in DARTWARS
Marco Faverzani, Pietro Campana, Rodolfo Carobene +46
Superconducting parametric amplifiers offer the capability to amplify feeble signals with extremely low levels of added noise, potentially reaching quantum-limited amplification. T…
