Modeling the Quantum Photon Statistics in Hybrid Light-Matter Integrated Circuits
Mathias Van Regemortel, Vincenzo Ardizzone, Eugenio Maggiolini +3
Strong light-matter coupling between a guided electromagnetic mode and an excitonic semiconductor transition gives rise to exciton-polaritons with optical nonlinearities far exceed…
Optimizing Quantum Photonic Integrated Circuits using Differentiable Tensor Networks
Mathias Van Regemortel, Thomas Van Vaerenbergh
Recent reports of large photonic nonlinearities in integrated photonic devices, using the strong excitonic light-matter coupling in semiconductors, necessitate a tailored design fr…
Monitoring-induced Entanglement Entropy and Sampling Complexity
Mathias Van Regemortel, Oles Shtanko, Luis Pedro Garcia-Pintos +4
The dynamics of open quantum systems is generally described by a master equation, which describes the loss of information into the environment. By using a simple model of uncoupled…
Bose-Einstein condensation of Efimovian triples in the unitary Bose gas
S. Musolino, H. Kurkjian, M. Van Regemortel +3
In an atomic Bose-Einstein condensate quenched to the unitary regime, we predict the sequential formation of a significant fraction of condensed pairs and triples. At short-distanc…
Engineering Gaussian states of light from a planar microcavity
Mathias Van Regemortel, Sylvain Ravets, Atac Imamoglu +2
Quantum fluids of light in a nonlinear planar microcavity can exhibit antibunched photon statistics at short distances due to repulsive polariton interactions. We show that, despit…
Spontaneous Beliaev-Landau scattering out of equilibrium
Mathias Van Regemortel, Wim Casteels, Iacopo Carusotto +1
We investigate Beliaev-Landau scattering in a gas of interacting photons in a coherently driven array of nonlinear dissipative resonators, as described by the 1D driven-dissipative…
Information propagation and equilibration in long-range Kitaev chains
Mathias Van Regemortel, Dries Sels, Michiel Wouters
We study the propagation of information through a Kitaev chain with long-range pairing interactions. Although the Lieb-Robinson bound is violated in the strict sense for long-range…
Probing the collective excitations of a spinor polariton fluid
M. Van Regemortel, M. Wouters, F. M. Marchetti
We propose a pump-probe set-up to analyse the properties of the collective excitation spectrum of a spinor polariton fluid. By using a linear response approximation scheme, we carr…
Negative drag in nonequilibrium polariton quantum fluids
Mathias Van Regemortel, Michiel Wouters
The possibility of a negative drag force on a defect in nonequilibrium polariton quantum fluids is presented. We relate this phenomenon to the selective parametric amplification of…
