The Nobel Prize 2023 in #physics Congratulations to the French researcher #PierreAgostini, French-Swedish atomic physics professor Anne L'Huillier and Austrian-Hungarian physicist #FerencKrausz. They were rewarded for their work on attosecond physics, which enables the creation of really short #laser pulses that allow you to follow the super-fast movement of electrons inside molecules. The #attosecond is currently the smallest measurable unit of time (one billionth of a billionth of a second). Applications of attosecond physics are expected in a large variety of areas, from atomic and molecular physics, to surface physics, plasmonics and ultrafast coherent imaging.

From September 13th to 16th, Dr. Sebastian Trojanowski, a member of the Astroparticle Physics group of AstroCeNT, participated in the international #SCALARS2023 conference, which was organized at the Faculty of Physics, University of Warsaw. At the meeting, Dr Trojanowski presented an invited plenary talk about the prospects for new physics searches in the ongoing and future searches in the far-forward kinematic region of the #LHC. This new experimental program aims at precision high-energy neutrino measurements and targets potential light new physics species that could be related to mysterious dark matter.

The last two weeks I have presented and discussed my research at two wery different conferences: Graphene Week in Gothenburg and TeVPa in Naples. The former is dedicated to graphene and other 2D materials, whereas the latter is dedicated to astroparticle physics. Working on the intersection of astroparticle and condenced matter physics has given me insight and allowed me to explore both these fascinating fields. #gw2023 #grapheneweek #grapheneweek2023 #grapheneflagship #graphene #tevpa #tevpa23

Discovering the secrets of the atoms - Karl Manne Georg Siegbahn won the #NobelPrize in Physics in 1924 for his pioneering work on X-ray spectroscopy. Born on December 3, 1886, Siegbahn made accurate measurements of the X-ray wavelengths produced by different atomic elements, which led to the discovery of new components in spectral lines.

Congratulations to my co-authors Maximilian Weissflog, Romain Dezert, Sina Sinaravi and Adrien Borne for the publication of our article Nonlinear nanoresonators for Bell state generation (https://lnkd.in/eZt9a2Dr)! In this work, featured in Applied Physics Reviews special issue on Quantum Metamaterials, we explore the possibilities offered by nonlinear nanoresonators as miniaturized sources of biphoton states with highly complex and tunable properties. Thanks to a new modeling approach, we unveil, amongst others, a regime where the generated multimode biphoton state is maximally entangled in the polarization degree of freedom, and naturally frequency entangled in a very broad spectral range. This contributes to the understanding of the physics of photon-pair generation in nanoscale systems, and stresses out that those systems are natural canditates for the future quantum technologies.

OMG, here comes the end of game big boss of #Exographer : the #HiggsBoson. In our game, you'll have to solve four analyses to defeat him. (For the particle physicists here, they are gamma gamma, 4 leptons, b bbar, and ttH). The fact that you will do that in year 12 of the post-absurd era is not a coincidence ;-) #Exographer was developped at the Science and Videogame academic chair of École Polytechnique, transfered to SciFunGames, and edited by Abylight Studios. Demo is already availble on Steam, link below.

The Higgs boson discovery confirms the Standard Model, but leaves unanswered questions about dark matter, antimatter, and potential new physics. Thus further exploration and research in particle physics is necessary. Enter bigger, powerful accelerators. Sure very expensive, but space-based particle accelerators in the moon or in zero gravity, could achieve higher energies and better vacuum, thus potentially unlocking new physics discoveries beyond Earth-based limitations.

The Nobel Prize in Physics rewards experiments with light that capture "the shortest of moments" and opened a window on the world of electrons. Another Noble Prize for ultrashort light! Actually, this does not surprise us. The advent of ultrashort light sources and attosecond metrology has greatly advanced the understanding of electron motion in atoms and molecules. Ultrafast electron motion can be encountered in many quantum systems. Therefore, the application of ultrashort radiation pulse encompasses a broad range of fields, extending from chemical sciences to condensed matter physics.

According to quantum physics, light and other electromagnetic radiation appear in the form of quanta, packets with fixed energies, which also correspond to energy transitions in atoms. Consequently, determining the frequency of light waves provides information about the atoms' properties, benchmarks for time and length, and the possibility of determining physical constants. Around the year 2000, Theodor Hänsch (pictured) and John Hall developed the frequency comb technique, in which laser light with a series of equidistant frequencies is used to measure frequencies with great precision. They were awarded the 2005 Nobel Prize in Physics for "their contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique."
