When perturbing a system, it will necessarily stay out of equilibrium for a time known as the relaxation time. Shortcutting this relaxation time may help improve nanomachines’ efficiency and force sensing scheme.In a recent work published in Physical Review Letters, … Continue reading →

Nanographene materials are promising building blocks for the growing field of low-dimensional materials for optics, electronics and biophotonics applications. In particular, bottom-up synthesized 0D graphene quantum dots show great potential as single quantum emitters. To fully exploit their exciting properties, … Continue reading →

Levitation of nanodiamonds is a promising platform for spin-optomechanics experiments and the study of quantum physics at the mesoscale.However, the temperature of levitated particles in optical tweezers, especially diamonds, is an essential element of this goal, and its characterization is … Continue reading →

In a recently published paper, we highlighted how the internal temperature of a levitated nanodiamond impacts its motion, an effect known as hot Brownian motion. To measure the diamond internal temperature, we used NV centers, point-like defects of the diamond … Continue reading →

In a recent article published in Nanoscale, in association with the theory team of D. Beljonne from Uni. Mons, collaborators from CEA NIMBE,and LPENS, we studied the effect of vibration and aggregation on the optical emission of Graphene Quantum Dots. … Continue reading →

Recently our team presented two of its activities in short videos (in French). If you want to know more about nano-light source made from perovskites crystals, please follow Cédric Damien, will tell you everything on how a single optically levitated … Continue reading →
