Welcome Kaina !

Posted on by

Autumn is the season of falling leaves but also of postdoctoral researchers arrivals and we welcomed this week Kaina Gonçalves Diniz, from Brazil. Kaina came in the context of the CAPES-COFECUB exchange program and will stay about one year in the lab. He graduated with a Bachelor’s degree in Physics from the Federal University of Rio de Janeiro, where he also completed his Master and PhD. He is primarily an experimental physicist, with a research focus on optical tweezers and their applications. He is also interested in chiral nanoparticles and has explored how these particles can be studied in the context of optical trapping. Welcome Kaina !

Welcome John !

Since last week, we have the pleasure to welcome a new postdoctoral researcher, John Ricca. John is the first north american postdoc in the lab and was born in Florida. He received his phD in chemistry from Florida Atlantic University in 2024 , where he carried out research in environmental analytical chemistry, biochemistry and physical chemistry.

Welcome to him !

Visit and seminar of Dr Dago

Posted on by

Dr. Salambô Dago (Vienna Center for Quantum Science and Technology (VCQ) University of Vienna) will visit our lab from today till Friday. Tomorrow, Thursday September 12th at 14:00 am, she will give a seminar at the Centre Européen de Sciences Quantiques (CESQ) on the Cronenbourg campus, entitled :

Two applications of feedback control on a nano and micro-system: Thermodynamic of Information & Optical Levitation in the Dark

A summary of the talk can be downloaded here. Do not hesitate to contact Cyriaque Genet if you would like to meet Dr. Dago during her visit

Bye bye Luis !

Luis Pires, who spent three years and a half among us, as a phD student and then as a postdoctoral researcher, left the lab mid-July to go back to Brazil. He got a position of assistant professor in the Physics Department at the Federal University of Viçosa (UFV).

Congratulations Luis and all the best for your future !

New doctors

Lab hiking

Posted on by

Last friday we took the time to have a lab outing. Weather was a bit uncertain but we did a nice 15 km walk around the Mont Saint-Odile, with some highlights like an unexpected detailed explanation about Ottrott’s castles, a picnic under the rain, a short visit of Hohenbourg abbey and a miraculous water tasting…. Congratulations to all the hikers !

Poster Prize for Anjali !

Spring publication

Posted on by

Our latest paper, presenting results obtained in collaboration with two other groups from ISIS (Joseph Moran‘s group and Giulio Raggazon‘s group) has just been accepted in Angewandte Chemie. Fabry-Perot optical cavities were developed to characterize Vibrational Strong Coupling (VSC) by Nuclear Magnetic Resonance (NMR) spectroscopy and we demonstrate that the London dispersion-driven conformational equilibrium of a molecular balance is altered when the C–H stretching vibration is strongly coupled to the cavity. Unexpectedly, VSC does not substantially affect molecular electron density distributions which has profound implications for the possible mechanisms at play in polaritonic chemistry.
