Competing Soft Modes and Tunable Multicriticality in a Generalized Two-Mode Quantum Rabi Model
Xiufeng Cao, Ofri Adiv, Neil G. R. Broderick
Multicritical phenomena play a central role in quantum many-body systems, yet their microscopic origin in light--matter platforms remains largely unexplored. Here we investigate a…
Strongly resonant polarization dynamics of pulse trains in a spin-flip model for an excitable microlaser with delayed self-feedback
Stefan Ruschel, Sylvain Barbay, Neil G. R. Broderick +1
Motivated by recent experimental observations concerning the polarization dynamics in an excitable microlaser with saturable absorber coupled to an external feedback mirror reporte…
A kneading map of chaotic switching oscillations in a Kerr cavity with two interacting light fields
Rodrigues D. Dikandé Bitha, Andrus Giraldo, Neil G. R. Broderick +1
Optical systems that combine nonlinearity with coupling between various subsystems offer a flexible platform for observing a diverse range of nonlinear dynamics. Furthermore, engin…
Regenerative vectorial breathers in a delay-coupled neuromorphic microlaser with integrated saturable absorber
Stefan Ruschel, Venkata A. Pammi, Rémy Braive +5
We report on the polarization dynamics of regenerative light pulses in a micropillar laser with integrated saturable absorber coupled to an external feedback mirror. The delayed se…
Bifurcations of Periodic Orbits in the Generalised Nonlinear Schrödinger Equation
Ravindra Bandara, Andrus Giraldo, Neil G. R. Broderick +1
We focus on the existence and persistence of families of saddle periodic orbits in a four-dimensional Hamiltonian reversible ordinary differential equation derived using a travelli…
Spontaneous symmetry breaking in a coherently driven nanophotonic Bose-Hubbard dimer
B. Garbin, A. Giraldo, K. J. H. Peters +7
We report on the first experimental observation of spontaneous mirror symmetry breaking (SSB) in coherently driven-dissipative coupled optical cavities. SSB is observed as the brea…
