Quest for Vortices in Photon Condensates
Himadri S. Dhar, Zai Zuo, João D. Rodrigues +2
We predict that a photon condensate inside a dye-filled microcavity forms long-lived spatial structures that resemble vortices when incoherently excited by a focused pump orbiting…
Towards a kinetic theory of a dark soliton gas in one-dimensional superfluids
C. Pereira, J. D. Rodrigues, J. T. Mendonça +1
Soliton hydrodynamics is an appealing tool to describe strong turbulence in low-dimensional systems. Strong turbulence in quasi-one dimensional spuerfluids, such as Bose-Einstein c…
Phase transitions of light in a dye-filled microcavity: observations and simulations
R. A. Nyman, H. S. Dhar, J. D. Rodrigues +1
Photon thermalisation and condensation in dye-filled microcavities is a growing area of scientific interest, at the intersection of photonics, quantum optics and statistical physic…
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…
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…
Axion production in unstable magnetized plasmas: an active source of dark-matter
J. T. Mendonça, J. D. Rodrigues, H. Terças
Axions, the hypothetical particles restoring the charge-parity symmetry in the strong sector of the Standard Model, and one of the most prone candidates for dark matter, are well-k…
Roton-Induced Trapping in Strongly Correlated Rydberg Gases
João D. Rodrigues, Luís F. Gonçalves, Hugo Terças +2
Atoms excited into high-lying Rydberg states and under strong dipole-dipole interactions exhibit phenomena associated with highly correlated and complex systems. We perform first p…
Turbulence Excitation in Counter-Streaming Paraxial Superfluids of Light
João D. Rodrigues, José T. Mendonça, Hugo Terças
Turbulence in the quantum (superfluid) regime, similarly to its classical counterpart, continues to attract a great deal of scientific inquiry, due to the yet high number of unreso…
Axion-plasmon polaritons in strongly magnetized plasmas
H. Terças, J. D. Rodrigues, J. T. Mendonça
Axions are hypothetical particles related to the violation of the charge-parity symmetry, being the most prone candidates for dark matter. Multiple attempts to prove their existenc…
Emergence of Spatial Order in Highly Interacting Rydberg Gases
João D. Rodrigues, Hugo Terças, Luis F. Gonçalves +2
We describe the emergence of strong spatial correlations, akin to liquid-like behavior and crystallization effects, in low (one and two) dimensional gases of cold Rydberg atoms. Th…
Excitation of high orbital angular momentum Rydberg states with Laguerre-Gauss beams
J. D. Rodrigues, L. G. Marcassa, J. T. Mendonça
We consider the excitation of Rydberg states through photons carrying an intrinsic orbital angular momentum degree of freedom. Laguerre-Gauss modes, with a helical wave-front struc…
Bump-on-tail instability of twisted excitations in rotating cold atomic clouds
J. D. Rodrigues, H. Terças, J. T. Mendonça
We develop a kinetic theory for twisted density waves (phonons), carrying a finite amount of orbital angular momentum, in large magneto optical traps, where the collective processe…
