Coherent Control of a Polariton Continuous Time Crystal

I. Carraro-Haddad, G. Usaj, A. Fainstein +3

Spontaneous breaking of time-translation symmetry and the emergence of self-sustained oscillations in quantum driven-dissipative systems is the hallmark of continuous time crystals…

Optimisation and Precision Tuning of Localised Surface Plasmon Resonance in AuFON Systems

Luis Alfonso Guerra Hernández, Osmar Gil Salas, Jorge Enrique Rueda Parada +2

Metal film on nanosphere (MFON) plasmonic systems have emerged as nanostructures with useful properties for molecular detection. This work presents the optimisation and discussion…

Ground state exciton-polariton condensation by coherent Floquet driving

Alexander Kuznetsov, Ignacio Carraro-Haddad, Gonzalo Usaj +3

The on-demand selective population transfer between states in multilevel quantum systems is a challenging problem with implications for a wide-range of physical platforms including…

Polariton cascade phonon laser

I. Papuccio-Fernández, A. A. Reynoso, A. E. Bruchhausen +5

Phonon lasers, as their photon counterparts, rely on the physics of stimulated emission. Arguably, because light does not require a material substrate to propagate, while sound doe…

Theory of Optomechanical Locking in Driven-Dissipative Coupled Polariton Condensates

I. A. Ramos-Pérez, I. Carraro-Haddad, F. Fainstein +5

The ubiquitous phenomenon of synchronization is inherently characteristic of dynamical dissipative non-linear systems. In particular, synchronization has been theoretically and exp…
