Promoting the extended SPP theory at the 6th LIPSS workshop in Heraklion (Crete)

With great mates in Heraklion after the LIPSS workshopThe 6th international LIPSS (Laser Induced Perodic Surface Structures) workshop was held in FORTH University of Heraklion, in Crete.

The latest developments of the theory on Surface Plasmon Polaritons (SPP) adapted for laser ablation conditions were presented in an invited talk, after 1st publication of the project appeared online. The future open-source tool for performing predictions of surface nanostructuring by lasers was promoted.

An abstract of the presented work is available on the BAM repository.

2 weeks of training at the Benasque TD-DFT school

Participation to Benasque School of TD-DFT 2016The “Benasque school of physics” hosts famous physics school all along the year. This year, I could attend to the “Time-Dependent Density Functional Theory: Prospects and Application” for a duration of 2 weeks. The school is composed of 1 week of lessons, including the week-end, and one week of workshop to get a view on the latest developments in the field of TD-DFT and beyond.

See the website for more information.

Roger Kelly award obtained at “Lasers in Materials Science” school of Venice, Italy.

 

Poster session in Venice, ItalyOn July 10, 2016, Dr. Thibault J.-Y. Derrien and Dr. Yoann Levy travelled to Venice, Italy for the 5th International School “Lasers in Materials Science” on the Isola de San Servolo, home to Venice International University.

The school was directed by Maria Dinescu (National Institute for Laser, Plasma and Radiation Physics, Bucharest, Romania), David B. Geohegan (Oak Ridge National Laboratory, USA), Antonio Miotello (Trento University, Italy), and Paolo M. Ossi (Politecnico di Milano, Italy). The School provided undergraduate students, PhD students and young research scientists with a wide opportunity to learn on fundamental roots of the interactions of laser light with different materials that are usually missed in traditional programs. The attendees were offered with 18 lectures from world-leading scientists, ranging from fundamentals of laser-matter interaction to scientific and industrial applications in various fields including new material production and bio-medicine.

One of the lectures was given by the RP4 Leader Nadezhda Bulgakova. The school also provided excellent opportunities of interactions and establishing cooperation with other researchers and colleagues working in similar, yet diverging fields.

Yoann presented work on Temperature relaxation after modulated absorption of femtosecond laser pulse in gold and fused silica in the LIPSS formation regime and Thibault presented work on the Role of electron-hole pair dynamics in modification of silicon upon femtosecond laser irradiation.

For his excellent work and presentation, Thibault Derrien was awarded the 2nd place among “Rising Stars” (Third Year PhD and Post-doc researchers) in the schools poster competition in memory of Prof. Roger Kelly.

Invited at the French-Czech “Young Talented Scientists” forum, Prague

Meeting French Institute of Praha

I was invited by the French Institute of Prague to attend and present my works at the “Young Talented Scientists” forum, which was held at the French Embassy of Czech Republic, on the 21st of June 2016, Prague.

A lunch with the French Ambassador in Czech Republic, Jean-Pierre Asvazadouria, and a debate on the mobility of researchers with the Nobel Laureate of Chemistry Jean-Marie Lehn was organized at the French Embassy.

The main outcome was to prepare advises to communicate with both French and Czech governments to improve the scientific mobility programs between the two countries.

Official report and pictures can be found on the website of the French Embassy.

Invited talk at EMRS Spring Meeting, Lille (2016)
