RT Journal Article T1 Energy Transfer between Colloids via Critical Interactions A1 Martínez Sánchez, Ignacio Aquilino A1 Devailly, Clemence A1 Petrosyan, Artyom A1 Ciliberto, Sergio AB We report the observation of a temperature-controlled synchronization of two Brownian-particles in a binary mixture close to the critical point of the demixing transition. The two beads are trapped by two optical tweezers whose distance is periodically modulated. We notice that the motion synchronization of the two beads appears when the critical temperature is approached. In contrast, when the fluid is far from its critical temperature, the displacements of the two beads are uncorrelated. Small changes in temperature can radically change the global dynamics of the system. We show that the synchronisation is induced by the critical Casimir forces. Finally, we present the measure of the energy transfers inside the system produced by the critical interaction.
