Successful Summer School

[14.08.2017] „Non-equilibrium dynamics“ on the German North Sea coast: About 45 graduate students and postdocs exchanged with national and international researchers and project instructors from the CRC 1242 on current scientific topics from 7 to 11 August 2017 in St. Peter-Ording. In addition to exciting poster sessions, a special highlight was the lecture "Inside Nature-branded journals" by Dr. Luke Fleet, Senior Editor at Nature Physics.

Dies academicus 2017

Outstanding Dissertation

[29.06.2017] Celebrate the best: At the „Dies academicus“, outstanding scientific performances and the most innovative ideas have been awarded at the University of Duisburg-Essen (UDE). At this year's ceremony on 28 June, the experimental physicist Dr. Tim Frigge from the working group of Prof. Michael Horn-von Hoegen received a prize for his dissertation on "Ultrafast structural non-equilibrium dynamics of the optically excited Si(111)(8x2)->(4x1)-In phase transition". In this, Frigge investigated initial structural dynamics of the photoinduced melting of a charge density wave in atomic chains of Indium on a Silicon(111) surface.

Doctoral Retreat

Sharing Ideas

[10.05.2017] Open discussions between peers to sharing ideas: About 25 scientists are going to meet at the Doctoral Retreat of the CRC 1242 from 15 to 17 May 2017 in the „Akademie Klausenhof“ in Hamminkeln. In an open atmosphere lectures, talk sessions, a poster circle and joint activities provide the opportunity to inform themselves about current research and to strengthen the collaboration.

Report in Nature: Observing Live Phase Transition

Watching the Atoms Race

[30.03.2017] By comparison, a blink lasts a lifetime – atoms can rearrange themselves within one 350 quadrillionths of a second. As reported in the latest issue of the prestigious journal Nature, scientists of the Center for Nanointegration (CENIDE) and the CRC 1242 at the University of Duisburg-Essen (UDE), together with their colleagues from the University of Paderborn, have been able to observe the movement of an one-dimensional material in real-time. Their research confirms that the acceleration of the atoms could leave even a Porsche standing.

The orbital angular momentum of plasmons caught on video

[17.03.2017] Transmitting huge volumes of data and even moving matter using light: These are two of the visions that physicists working in the field of plasmonics have for the future. In a collaboration with colleagues from Haifa (Israel), Kaiserslautern and Stuttgart, scientists at the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen succeeded in producing nanometer-sized plasmon swirls on a metal surface, filming the cycles at 100 attosecond intervals.

The video can be found here. The complete press release can be found here.

UDE: 2D Material withstands extremely high current densities

Graphene under Fire

[06.02.2017] The particle penetrated the ultra-thin sample with speeds of up to 450 km/s, yet everything
stayed in one piece: This is what happened to a team of international scientists, among them Professor Dr. Marika Schleberger from the Center for Nanointegration (CENIDE) of the University Duisburg-Essen (UDE). Her sample of freestanding graphene was able to balance out the charge of a high-energy ion within femtoseconds and thus prevent a nanoscale explosion. “Nature Communications” reported on this in its  latest issue.

International Symposium

Ultrafast Soft X-Ray Spectroscopy and Scattering

[16.01.2017] International symposium on ultrafast soft x-ray spectroscopy and scattering on Friday, 27 January: The Collaborative Research Center 1242 of the Faculty of Physics and the Center for Nanointegration Duisburg-Essen (CENIDE) invite you to attend at the NanoEnergyTechnologyCenter (NETZ) on campus Duisburg. International experts exchange ideas such as how to apply the processes and methods for element-specific analysis in complex nanostructures.

Please find directions and a detailed program here.

Research into Superconductors

Tracking the Flow of Energy by Laser

[20.12.2016] Below their critical temperature they conduct the electrical current without resistance and thus extremely efficiently: Until now it has only been known that high-temperature superconductors work – but not how. Physicists at the University of Duisburg-Essen (UDE) have succeeded in tracking the redistribution of the energy in the material. To do this they used a medium which is itself fast enough to register these processes – light. The "Nature Communications" journal has just published their results.

Kick-Off-Meeting

Teaming up for Success!

[25.11.2016] Getting to know each other better, professional exchange and networking: Around 80 scientists met at the kick-off-meeting of the CRC 1242 from 21 to 23 November 2016 in the conference center „Physikzentrum“ in Bad Honnef. Numerous lectures, poster presentations and joint activities such as hiking provided the opportunity to inform themselves about current research and to strengthen the cooperation. External speakers from renowned institutions were also invited.

Major Success for the Faculty of Physics

New Collaborative Research Centre

[31.05.2016] The competition was of a very high standard: Numerous groups of researchers applied for a new Collaborative Research Centre (SFB). "In view of the large, nationwide competition, we are very happy that the Deutsche Forschungsgemeinschaft opted for our application", said a very pleased Prof. Dr. Uwe Bovensiepen, Head of the Ultrafast Dynamics at Interfaces group of researchers in the Faculty of Physics of the University of Duisburg-Essen (UDE). "At the same time, this decision confirms our leading role in an important field of physics", explained the future SFB spokesperson.
