Transport and localization of light inside a dye-filled microcavity
Himadri S. Dhar, João D. Rodrigues, Benjamin T. Walker +3
The driven-dissipative nature of light-matter interaction inside a multimode, dye-filled microcavity makes it an ideal system to study nonequilibrium phenomena, such as transport.…
Learning the Fuzzy Phases of Small Photonic Condensates
João D. Rodrigues, Himadri S. Dhar, Benjamin T. Walker +4
Phase transitions, being the ultimate manifestation of collective behaviour, are typically features of many-particle systems only. Here, we describe the experimental observation of…
Wave scattering from rough surfaces for good mirrors
Robert A. Nyman, Benjamin T. Walker
This document takes existing derivations of scattering loss from rough surfaces, and makes them more accessible as a tool to derive the total scattering loss from a rough mirror gi…
Non-stationary Statistics and Formation Jitter in Transient Photon Condensation
Benjamin T. Walker, João D. Rodrigues, Himadri S. Dhar +3
While equilibrium phase transitions are well described by a free-energy landscape, there are few tools to describe general features of their non-equilibrium counterparts. On the ot…
Collective excitation profiles and the dynamics of photonic condensates
Benjamin T. Walker, Henry J. Hesten, Robert A. Nyman +1
Photonic condensates are complex systems exhibiting phase transitions due to the interaction with their molecular environment. Given the macroscopic number of molecules that form a…
Non-critical slowing down of photonic condensation
Benjamin T. Walker, Henry J. Hesten, Himadri S. Dhar +2
We investigate the response of a photonic gas interacting with a reservoir of pumped dye-molecules to quenches in the pump power. In addition to the expected dramatic critical slow…
