On Wed. 10th April, 10am, T. J.-Y. Derrien will present an invited seminar at the Max Planck institute for Structure and Dynamics of matter (MPSD), in the Theory Department of Prof. Angel Rubio.
Announced title of the seminar is “Time-dependent density functional theory for femtosecond laser engineering of solids”.
In 2016, TJY Derrien spent 6 months in the Theory Department of Prof. A. Rubio as guest scientist of Marie Sklodowska-Curie Actions (Individual Fellowship). In 2018, he spent 1 year at MPSD as a post-doctoral scientist. There he was introduced to Quantum Electrodynamics and applied for ERC funding, with help from Dr. Micheal Ruggenthaler who is now permanent group leader at the MPSD.
There, he also met with numerous other excellent scientists among whom several joined the group of Prof. Prineha Narang located in Harvard (USA) at that time. In 2024, Prof. Narang (now permanent at UCLA) visited the Czech Republic as “Quantum ambassador” via the Embassy of United States in the Czech Republic.
The program represented a number of diplomatic landscapes for funding scientific research between France, Czech Republic and Slovakia. It covered the following parts.
Marie Curie Post-doctoral Fellowships (MSCA/PF),
ERA Fellowships / ERA talents,
Program Hubert Curien (PHC) “Barrande” for PhD scholarships between France and Czech Republic,
a summary of Czech, Slovak and French landscapes for funding researchers,
an applicant guideline on how to find a host,
a testimony of experience by Thibault JY Derrien (Marie Curie Individual Fellowship 2015 – 2017, and RISE fellow 2019 – 2024).
2 PhD students from the University of Cuyo (Mendoza, Argentina) Andrés I. Bertoni and Micaela J. Sosa have visited the HiLASE laboratory during 2 months. While hot summer took place in Argentina, Andrés and Micaela have successfully braved the Czech winter.
Their 2-months stay was funded by the Marie Curie project ATLANTIC.
Out of their stay, they managed to enlarge the scope of the group activities to biology and to chemistry using microscopic modeling. They both contributed to the ATLANTIC project deliverables and knowledge exchange, a mission that Marie Curie Actions stand for.
The cultural exchange has also been excellent, sharing empanadas (!), music events, discussions in Spanish, and even in Czech. As a result, Czech-Argentinian relations have never been so well developed.
Their stay is definitely what Marie Curie Actions can offer at its best. We look forward to seeing them again with greatest pleasure.
The SLA department that hosts our research group has obtained a joint project OPJAK (Ministry of Research) in collaboration with several groups of the Institute of Physics (AS CR).
Our group is therefore prolonged by 1 year up to 2 FTE, counting 1 FTE for Dr. TJY Derrien, 0.5 FTE for Krystof Hlinomaz and 0.5 FTE for Kristyna Gazdova, effective from January 1st.
Krystof is planned to spend 0.5 FTE at TopTec (Turnov) and Kristyna has equivalent PhD contract in Brno.
TJY Derrien, head of the computational group of Ultrafast Photonics at HiLASE, attended the 7th IT4I supercomputer users meeting. The annual workshop is excellent to meet with colleagues from best computational groups of the country from IOCB, FZU, CEITEC Brno, CATRIN Olomouc, Institute of Plasma Physics, ELI beamlines, IT4I, and more.
There, TJYD delivered an oral presentation titled „Benchmark of time-dependent density functional theory simulations on a variety of European CPU-based supercomputers“. In this communication, he presented a summary of the predictions obtained using quantum numerical simulations (time-dependent density functional theory, TDDFT) along with an overview of high performance computation analyses gathered since 2016 on a variety of Top500.org CPU-based super-computers.
He also attended the meeting with the Users Council as secretary and chaired the 2 sessions of presentations of Tuesday.
The IT4I center has been the main working tool of our computational group since 2019 and has been strategic for contributing to high impact factor studies with our collaborators.
On Oct. 18th-20th 2023, TJY Derrien, head of the group of Ultrafast Photonics, has participated and gave an oral presentation at the Laser63 conference, a Czech conference organized by the Czech Academy of Sciences, that gathers Czech scientists and laser industrial ecosystem from the Czech Republic.
Beyond the language barrier, it was very appreciable to meet new collaborators and very important for enabling further sustainability to deliver a summary on our capacity to prepare predictive numerical simulations for fs and ps laser interaction with materials.
The press releases prepared by HiLASE are here: website | LinkedIn.
The website of the Czech conference Laser63 is here (in Czech).
Today, a new joint paper with the team of Martin Kozak of the Charles University was submitted for publication. The paper draft is available here and demonstrates an extraordinary agreement obtained between the harmonics generated from a silicon target irradiated with temporally-overlapping ultrashort laser pulses with the predictions prepared using the time-dependent density functional theory (TDDFT).
The paper suggests that the TDDFT simulation technique is sufficiently mature for making high-precision predictions for ultrashort laser processing and beyond.
TJY Derrien, leader of the Ultrafast Photonics group, was invited in the frame of CSIC-ILINK project for a duration of two weeks at the Instituto de Optica, CSIC, Madrid, Spain.
During this stay of 2 weeks in company of Prof. Javier Solis, Prof. Jan Siegel, Dr. Jörn Bonse, and Dr. Mario Garcia-Lechuga (project host), fruitful and exciting collaboration was initiated in view of preparation of a future joint funding.
During his visit, TJY Derrien gave seminar at the Instituto de Optica on Thu 5th of October, along with Prof. Jörn Bonse. Abstracts are available here.
LIPSS workshop
During the stay, the LIPSS workshop was also organized by Prof. Esther Rebollar and co-organizers.
We warmly thank our hosts for this wonderful hosting time and look forward to the next steps together!
