Highly squeezed states in ring resonators: Beyond the undepleted-pump approximation
C Vendromin, Y Liu, Z Yang, JE Sipe - Physical Review A, 2024 - APS
We present a multimode theory of squeezed-state generation in resonant systems valid for
arbitrary pump power and including pump depletion. The Hamiltonian is written in terms of …

Mean-field and cumulant approaches to modelling organic polariton physics
P Fowler-Wright - arXiv preprint arXiv:2405.09812, 2024 - arxiv.org
In this thesis we develop methods for many-body open quantum systems and apply them to
systems of organic polaritons. The methods employ a mean-field approach to reduce the …

Quantum metrology in a driven-dissipation down-conversion system beyond the parametric approximation
D Xie, C Xu - arXiv preprint arXiv:2404.15898, 2024 - arxiv.org
We investigate quantum metrology in a degenerate down-conversion system composed of a
pump mode and two degenerate signal modes. In the conventional parametric …
