(Real) Symposium on imaginary numbers

The first symposium of the Quantum Think Tank Strasbourg <Q|TT|S>, entitled

Les Imaginaires en Physique Quantique

will take place on February 5, from 2 to 5 pm, in ISIS conference room. The two speakers, Marc-Olivier Renou and Frédéric Patras will discuss (in french !) about the role and meaning of imaginary and complex numbers in physics. This event is organized in the framework of the ITI QMat and you can find more information here : https://qtts.ipcms.fr/

Luis’ defense and minisymposium

December is placed under the sign of Brasil in the lab this year, maybe because we miss the sun and the heat, and after the visits of Felipe A. Pinheiro and of Paulo Maia Neto, we are happy to announce the phD defense of Luis Pires.

His work, entitled Entropic costs for brownian protocols was carried out under the supervision of Dr Cyriaque Genet. The defense will take place in ISIS conference room at 9am, on Thursday 14th of December.

On this occasion, a minisymposium about Thermodynamics of fluctuating systems is organized, same place, on Wednesday 13th, 2.30pm, gathering Sabine Klapp (TU Berlin), Paulo Maia Neto (UFRJ Rio de Janeiro), Yann Louyer (LOMA, Bordeaux) and Loïc Rondin (LuMIn, Paris-Saclay). The abstracts of the talks can be downloaded here.

Seminar Pr Felipe A. Pinheiro

Pr Felipe A. Pinheiro, from Federal University of Rio de Janeiro (Brazil), will visit us on Monday 27 and Tuesday 28. On this occasion, he will give a seminar entitled

“Natural optical activity in disordered media and optical tweezing of chiral particles”

at the CESQ (Cronenbourg Campus) Tuesday 28 at 10.30am. If you wish to meet him during his stay, don’t hesitate to contact Dr Cyriaque Genet.




Shahana’s phD defense and Minisymposium

Shahana Nizar Nizar-Shyla will defend her phD work, entitled

Characterization of chiral supramolecular assemblies using Mueller polarimetry

and performed under the supervision of Cyriaque Genet, tomorrow September 20, at 9am in the seminar room of ISIS2 (2nd floor).

On this occasion, we will have this afternoon a minisymposium at 3pm (same place) “Chirality, from molecular engineering to high resolution chiroptical spectroscopy“, welcoming Jeanne Crassous from Rennes University and Anne Zehnacker-Rentien from Paris-Saclay University. Please have a look here for the abstracts of their talks.

Mini symposium on light-matter coupled materials

Seminar by Pr. Hiroshi Fukumura

Today, we have the pleasure to welcome Pr Hiroshi Fukumura (KU Leuven, Belgium, & Tohoku University, Japan) who will give a talk at 11am in the Salle de Conférence of ISIS, entitled

“Liquid-liquid phase separation dynamics: hierarchy from molecular level to continuous bulk”

Here below you can find the abstract of his talk :

Pulsed laser induced liquid-liquid phase separation has been studied with various time-resolved techniques. Time-resolved Raman spectroscopy and fluorescence spectroscopy revealed molecular level changes immediately after the laser pulses up to 1 . Ultrafast imaging under conventional microscopes showed macroscopic changes started 10 after the laser pulse. The macroscopic phase separation seemed to follow spinodal decomposition described by Kahn-Hilliard theory. It is, however, yet unclear what occurs in the time range between 1 and 10 . Recently we have succeeded in observing this time range with time-resolved structured illumination as well as optical diffraction techniques. Possible explanation of our results would be that mesoscopic entities like micelle-like structures mediate between molecular level changes and macroscopic spinodal decomposition. Related topics like liquid-liquid phase separation in living cells, critical Casimir force in binary liquids, laser ablation and implantation of polymer surfaces may be introduced.
