Synchronization in coherently and dissipatively coupled spinor polariton time crystals
I. Carraro-Haddad, A. Ramos-Pérez, G. Usaj +6
The spinor degree of freedom associated to exciton-polariton condensates can spontaneously self-oscillate breaking time translation symmetry, thus showing a continuous time-crystal…
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…
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…
Shapiro resonances in ac-self-modulated exciton-polariton Josephson junctions
I. Carraro Haddad, D. L. Chafatinos, A. A. Reynoso +6
We experimentally investigate the dynamics of exciton polariton Josephson junctions when the coupling between condensates is periodically modulated through self-induced mechanical…
Electronic and magnetic properties of graphene-fluorographene nanoribbons: Controllable semiconductor-metal transition
R. M. Guzmán-Arellano, A. D. Hernández-Nieves, F. M. Peeters +1
We investigate the electronic and magnetic properties of graphene channels (--~nm wide) embedded within fluorographene, focusing on two distinct interfaces: the fully fluorin…
