Nobelovu nagrada za fiziku dobilo troje naučnika

[Nina]

Nobelova nagrada za fiziku 2023. dodeljena je Pjeru Agostiniju, Ferencu Krauzu i Ani L'Hulije za "eksperimentalne metode koje generišu atosekundne impulse svetlosti za proučavanje dinamike elektrona u materiji", saopštila je Kraljevska švedska akademija nauka u Stokholmu.

Komitet je rekao da su trojica fizičara "pokazala način za stvaranje izuzetno kratkih impulsa svetlosti koji se mogu koristiti za merenje brzih procesa
u kojima se elektroni kreću ili menjaju energiju", što je "čovečanstvu dalo nove alate za istraživanje sveta elektrona u unutrašnjosti atoma i molekula", prenosi CNN.
"Doprinosi laureata omogućili su istraživanje procesa koji su toliko brzi da ih je ranije bilo nemoguće pratiti", navodi komitet.

Videćemo koji će rezultati biti sa tim atosekundnim impulsima.

Cisto da bude jasnije ljudima, mili mikro nano piko femto ato....
3,6,9, 12, 15 , 18, sto ce reci 10 na minus 18 sekunde traje svetlosni signal...
To su HHz frekvencije....

Culi ste za 20 nm procesorske tehnike pravljenja...3 nm je valjda najmanje komercijalno , nisam gledao skoro, cisto da znate koliko moze da se spusti litografija pravljenja cipova kad se upotrebe ato izvori svetlosti..

Nisam citao , ali to nisu vise ni rengen zraci , to shiba kroz materiju samo tako.....to su teski gama zraci..., jer po teoriji fotona, ne moze poslati trajanje svetlosti koje je krace od perioda svetlosti.....

Фотон је честица и нема никакав период, свјетлост може имати период само као талас. Знам, дуална природа, блаблабла... али бабе и жабе ипак не иду заједно.

In the 1990s, the groundwork for this landmark was done by Ferenc Krausz and his team with a large number of innovations to the further development of the femtosecond laser technology to its ultimate limits – towards light pulses which carry the major part of their energy in one single oscillation of the electromagnetic field. An indispensable prerequisite for the generation of such short light pulses is the high-precision control of the delay of the different color components of broadband (white) light over one entire octave. Aperiodic multi-layers (chirped mirrors) emerging from a collaboration of Ferenc Krausz and Robert Szipöcs made such a control possible and are indispensable in today's femtosecond laser systems.

In 2001, Ferenc Krausz and his group were able for the first time not only to generate but also to measure attosecond light pulses (of extreme ultraviolet light) by means of intense laser pulses consisting of one to two wave cycles. With this, they were shortly thereafter also able to trace the movement of electrons on the subatomic scale in real time. The control of the wave form of the femtosecond pulse demonstrated by Ferenc Krausz and his team and the resulting reproducible attosecond pulses enabled the establishment of the attosecond measuring technique as the technological basis for experimental attosecond physics today. Over the past few years, Ferenc Krausz and his coworkers succeeded with these tools to control electrons in molecules and – for the first time – observe in real time a large number of fundamental electron processes such as tunneling, charge transport, coherent EUV emission, delayed photoelectric effect, valence electron movement and the control of the optical and electrical properties of dielectrics. These results have been archived with international cooperations with groups of scientists such as Joachim Burgdörfer, Paul Corkum, Theodor Hänsch, Misha Ivanov, Ulrich Heinzmann, Stephen Leone, Robin Santra, Mark Stockman and Marc Vrakking.

L'Huillier was on the Nobel Committee for Physics between 2007 and 2015,[3] and has been a member of the Swedish Academy of Sciences since 2004.[6] In 2003, she received the Julius Springer Prize.

Jedna nagrada za eksperimentalnu metodu, zanimljivo...ali je bazicna...
