Developed by Martin Huppert and David Stapfer, Ultrafast Spectroscopy and Attosecond Science, ETH Zurich

02.06.2016

This experiment is designed to attract the general public by demonstrating the use of pendulums and waves. The idea of this experiment is to draw peoples' attention to science by a creating a fascinating moving and acoustic display, whilst also illustrating more complex scientific concepts that we use in MUST research. In an exhibition the scientists demonstrate this experiment in different phases.

The Zurich Physics Colloquium: Prof. Ursula Keller - Attosecond Ionization Time Delays

23.03.2016

The Zurich Physics Colloquium is jointly organized by the University of Zurich and the ETH Zurich. Its mission is to bring both students and faculty with diverse interests (astrophysics, condensed matter physics, high energy physics, quantum electronics/optics) into contact with newest scientific developments in natural sciences, predominantly physics but also biology, chemistry, and topics from environmental sciences. Leading experts explain the basic questions in their field of research and communicate the fascination for their work.

Jean-Pierre Wolf - The man who wants to control the weather with lasers - on CNN

(CNN, April 24, 2015) Is there anything laser can't do?

From cutting diamonds to preserving endangered sites, all the way to building terrifying weapons and turning your eyes from brown to blue, there is apparently no end to the list of applications for laser. Swiss physicist Jean-Pierre Wolf is working on yet another impressive addition to that list: using focused laser beams to affect the weather.

Fabrizio Carbone - Two-in-one photography: Light as wave and particle! (sous-titres français).

Light is a wave and a particle, but no-one's managed to see both at the same time.... until now!
The first ever snapshot of light as both wave and particle is taken by Fabrizio Carbone’s lab at EPFL (LUMES). The work is published in Nature Communications on 02 March 2015.

Téramobile la foudre domestiquée

Arriver à contrôler la foudre et faire pleuvoir sur demande est un vieux rêve de l'humanité. Il pourrait devenir réalité grâce à des chercheurs de l'Université de Genève. Ces derniers envoient des rayons lasers dans le ciel pour déclencher la foudre et créer des petits nuages.
Les explications de Jean-Pierre Wolf, professeur de physique à l’Université de Genève (Unige), au micro de Pierre Bratschi.

Physics at FOM Veldhuizen 2014, Ursula Keller, Opening Lecture


-Pho&ysv4icb3s@t&FOa1M p&Vef/lds+hob+ves$nn takes place each year in January. It is a large congress that provides a topical overview of physics in the Netherlands. Traditionally, young researchers are given the chance to present themselves and their work alongside renowned names from the Dutch and international physics community. The programme covers Light and matter, Atomic, molecular and optical physics, Nanoscience and nanotechnology,  Statistical physics and Soft condensed matter, Surfaces and interfaces, Physics of fluids, Subatomic physics, Plasma and fusion physics, and Strongly correlated systems. This year, Ursula Keller was invited to give the opening lecture, entitled "Attoclock: shining new light on old questions in quantum mechanics" (Abstract).


.

At the same meeting, Ursula Keller also held a Masterclass, entitled "Short-pulsed solid-state lasers enable an exciting journey from ultrafast laser physics to frequency metrology and attosecond science" (Abstract). Relevant publications: Keller-2010 - 20 Years Ultrafast Solid-State-Lasers; Telle-1999-Carrier-Envelope Phase Control; Eckle-2008 Attosecond Ionization.

SwissFEL -- the new large-scale facility at the Paul Scherrer Institute

The next large-scale facility at PSI -- the X-ray laser SwissFEL -- should come on-line in 2016. It will produce very short pulses of X-ray light, with laser-like properties. Researchers will be able to use these pulses to visualize extremely fast processes, such as how new molecules are created in a chemical reaction; to determine the detailed structure of vital proteins; or to determine the relationship between electronic and atomic structure in materials. From such studies, researchers will gain insights which are not possible to obtain with the methods available today. This new knowledge will expand our understanding of nature and lead to many practical applications; for instance, new pharmaceuticals, more efficient processes in the chemical industry, new materials for electronics, or alternative processes in energy production.

Kleinstteilchen im Laserlicht

Im interdisziplinären schweizerischen Grossprojekt NFS MUST wollen Physiker Feurer und die NFS-Leiterin Ursula Keller von der ETH Zürich einen «Einblick in die fundamentalen Abläufe der Natur gewinnen und damit auch den Grundstein für viele Anwendungen in der Medizin und erneuerbaren Energien legen», führt der Berner Physiker in einem Kurzfilm über den NFS MUST aus (Quelle: Uniaktuell - Universität Bern).



Knapp sechs Minuten über ultraschnelle Prozesse von Teilchen – ein Kurzfilm über den NFS MUST. (Video: Abt. Kommunikation Universität Bern/M.Moser/K.Sorgen).

Serie: «Frauen in Männerdomänen» – Die Physikerin (1/5)

Naturwissenschaft und Technik und dazu noch eine akademische Spitzenposition - auch heute ist dies noch immer hauptsächlich Männern vorbehalten. In einer Serie stellen wir fünf Professorinnen in wissenschaftlichen Männerdomänen vor. Zum Einstieg porträtiert «Einstein» Ursula Keller, seit über 20 Jahren Professorin für Physik. Sie war die erste Frau überhaupt, die an der ETH Zürich zur Professorin in einem naturwissenschaftlich-technischen Fach ernannt wurde – und strotzt vor Leidenschaft und Energie.

Ursula Keller: the return of the discussion on women quotas (in German)

November 14, 2012 on SRF



Die Schweiz ist ein Entwicklungsland – was die angemessene Vertretung von Frauen in den Führungsetagen angeht. Nun verlieren auch liberale Frauen ihren Glauben an freiwillige Massnahmen und die Hoffnung auf ein Umdenken der Männer. Eine «Kulturplatz»-Umfrage bei Frauen mit Erfahrungen in Top-Positionen belegt: Die Forderung nach einer Frauenquote ist mit Vehemenz zurück. Link >>

Vibrational photodissociation of sulfuric acid: The infrared laserpulse is shown as a lightflash which excites a local OH-stretching vibration. The vibrational energy is rapidly redistributed to torsional degrees of freedom from where the energy returns into the dissociative coordinate which eventually leads to breakup of the molecule into H2O and SO3 on a time scale of tens to hundreds of picoseconds.

The charge exchange reaction between an ultracold (micro-K) N2+ and a low-energy (8 K) beam of N2. Formation of the stable N4+ ion and subsequent decay into N2+ and N2 is observed on the several picosecond time scale.

Was unter Labor-Bedingungen bereits gut funktioniert, wird am Ufer der Rhone in Genf unter realen Wetterbedingungen untersucht: Energie eines Lasers lädt Wasser-Moleküle in der Luft auf - und schon beginnt der Wasserdampf zu kondensieren. Diese Wassertröpfchen sind allerdings winzig klein. Bis zum richtigen Regen ist es ein weiter Weg.
