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…
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…
