Excitation spectra and rank tomography of linear matrix product tangent spaces
Otto T. P. Schmidt, Iacopo Carusotto
We formulate a tangent-space method for algebraic varieties of matrix product states (MPS) to study excitation spectra of non-uniform quantum many-body systems with open boundary c…
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…
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…
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…
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…
