[institut] [phys4phys] IPB Colloquium: Dejan Milosevic, Monday, 30 October, 12:00

[Antun Balaz]

Dear colleagues,

You are cordially invited to the IPB COLLOQUIUM which will be held on Monday, 30 October 2023 at 12:00 in the “Zvonko Marić” lecture hall of the Institute of Physics Belgrade. The talk entitled

Attoscience – The Nobel Prize in Physics 2023

will be given by Prof. Dr. Dejan Milošević (Academy of Sciences and Arts of Bosnia and Herzegovina; University of Sarajevo, Faculty of Science, Bosnia and Herzegovina). The abstract of the talk:

Electrons and photons have played a central role in the scientific and technological revolution of the 20th century (discovery of transistor and laser; electronics and photonics). In the 21st century, the advance of science and technology has enabled observation of atomic-scale dynamics of electron motion, both in space and time. As a "child" of the strong-field physics, a new area of science - attoscience - has been born. The science is now able to describe electronic motion in atoms, molecules and nanoscale structures, and thus the borders between physics, chemistry and biology tend to disappear. On the other hand, the electronic motion is responsible for emission of lights. Emission of coherent light in the form of ultrashort soft X-ray pulses on the attosecond time scale is possible via high-order harmonic generation process.

The Nobel Prize in Physics 2023 was awarded to Pierre Agostini, Ferenc Krausz and Anne L'Huillier "for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter". In this lecture, I will first give a short introduction to attoscience, and then will present the Nobel Prize laureates, with whom I collaborated in the past, having common publications. In particular, I will present two crucial experiments for which the Nobel prize was awarded: the RABBITT (Reconstruction of Attosecond Beating By Interference of Two-photon Transitions) technique and the streaking experiment. I will also show some new results, such as attosecond double-slit experiment, and various applications of attoscience.


Best regards,
Antun Balaž
