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…
GHz control of THz QCL band structure and gain by standing acoustic strain
Alexander S. Kuznetsov, Valentino Pistore, Lutz Schrottke +2
Active frequency comb generation and waveform control are central challenges in the terahertz (THz) domain. In THz quantum cascade lasers (QCLs), these functions have typically bee…
Strong Coupling beyond the High-Q Limit and Linewidth Narrowing in a Multi-Exciton Planar Microcavity
E. A. Cerda-Méndez, Y. G. Rubo, K. Biermann +3
We systematically study the linewidths of multilevel exciton-polariton modes as a function of the detuning in a planar hybrid microcavity (MC) with low quality factor (Q~300) opera…
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…
Near-room-temperature zero-dimensional polariton lasers with sub-10 GHz linewidths
Ismael dePedro-Embid, Alexander S. Kuznetsov, Klaus Biermann +2
Narrow and brilliant spectral lines are essential assets for high-resolution spectroscopy as well as for precision sensing and optomechanics. In semiconductor structures and, in pa…
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…
Solid-state continuous time crystal with a built-in clock
I. Carraro Haddad, D. L. Chafatinos, A. S. Kuznetsov +7
Time crystals (TCs) are many-body systems displaying spontaneous breaking of time translation symmetry. Here, we demonstrate a TC using driven-dissipative condensates of microcavit…
Microcavity phonoritons -- a coherent optical-to-microwave interface
A. S. Kuznetsov, K. Biermann, A. Reynoso +2
Optomechanical systems provide a pathway for the bidirectional optical-to-microwave interconversion in (quantum) networks. We demonstrate the implementation of this functionality a…
