Abstract
The phase and the frequency of an exciton polariton condensate excited by a nonresonant pump can be efficiently manipulated by an external coherent light. Being tuned close to the resonance with the condensate eigenfrequency, the external laser light imposes its frequency to the condensate and locks its phase, thereby manifesting a synchronization effect. The conditions of formation of the phase synchronized regime are determined. The synchronization of a couple of closely spaced polariton condensates by a spatially uniform coherent light is examined. At the moderate strength of the coherent driving the synchronization is accompanied by the appearance of symmetry-breaking states of the polariton dyad, while these states are superseded by the symmetric state at the high-intensity driving. By employing a zero-dimensional model of coupled dissipative oscillators with both dissipative and conservative coupling, we study the bifurcation scenario of the symmetry-breaking state formation.

A strong light–matter interaction in semiconductor microcavities gives rise to formation of composite quasiparticles called exciton polaritons [1]
At the moderate strength of the coherent driving the synchronization is accompanied by the appearance of symmetry-breaking states of the polariton dyad, while these states are superseded by the symmetric state at the high-intensity driving
We describe a novel mechanism of manipulation of nonequilibrium condensates of exciton polaritons formed in semiconductor microcavities
Summary
Any further distribution of The phase and the frequency of an exciton polariton condensate excited by a nonresonant pump can this work must maintain be efficiently manipulated by an external coherent light. Being tuned close to the resonance with the attribution to the author(s) and the title of condensate eigenfrequency, the external laser light imposes its frequency to the condensate and locks the work, journal citation and DOI. The synchronization of a couple of closely spaced polariton condensates by a spatially uniform coherent light is examined. At the moderate strength of the coherent driving the synchronization is accompanied by the appearance of symmetry-breaking states of the polariton dyad, while these states are superseded by the symmetric state at the high-intensity driving.
