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 →

A video of Elsa describing her activities (in French)

A 2 years post doc position is available in the group on single molecule studies of graphene quantum dots. The hired postdoc will be involved first in the study of the graphene quantum dots photophysics and will take advantage of … 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 →

Elsa Cassette has been awarded of the CNRS bronze medal for her previous work carried out at LIDYL laboratory. Congratulations Elsa!

New paper in the group! In a study lead by Cédric Mayer, the group demonstrates a “Synthesis method of highly calibrated CsPbBr3 nanocrystals perovskites by soft chemistry.” As one can see on the image below, this original method leads to quasi … Continue reading →

After having been hosted for 3 years in the 520 building (ISMO), the group enters its new building (505) on the Paris Saclay campus! It is now time to rebuild all the experiments!

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 →
