Shining a light on nanoscale dynamics

Watching metamaterials at work in real time using ultrafast electron diffraction

26-Nov-2020

Physicists from the University of Konstanz, Ludwig-Maximilians-Universität München (LMU Munich) and the University of Regensburg have successfully demonstrated that ultrashort electron pulses experience a quantum mechanical phase shift through their interaction with light waves in nanophotonic ...

A single molecular switch reveals atomic-scale light dynamics

19-Nov-2020

Researchers at the the University of Regensburg and the MPSD in Hamburg have developed a groundbreaking method to detect the dynamics of light on such a small scale with high temporal resolution. Since the 17th century, researchers have explored tiny objects in their most fundamental detail using ...

Lightning-fast atomic hand

Not only observe individual molecules, but even control them

04-Sep-2020

Scientists from Regensburg and Zurich have found a fascinating way to push an atom with controlled forces so quickly that they can choreograph the motion of a single molecule within less than a trillionth of a second. The extremely sharp needle of their unique ultrafast microscope serves as the ...

Behind the veil of nothingness

International team of scientists controls custom quantum vacua much faster than light

13-Aug-2020

An international research team from Germany and France has created structures in which light fields interact with electrons so strongly that the quantum vacuum itself is significantly altered. Using extremely short bursts of light, they interrupted this coupling much faster than the timescale of ...

Initial repulsion does not rule out subsequent attraction

Scientists revealed intricate mysteries of chemical bonding

16-Sep-2019

The Philosopher Arthur Schopenhauer formulated a metaphor called the porcupine dilemma, which explains a certain optimal distance between people. People feel alone at too large a spacing and uneasy at too close a proximity. Schopenhauer explained the ideal spacing using the following parable: „A ...

A long-distance relationship in femtoseconds

Physicists observe how electron-hole pairs drift apart at ultrafast speed, but still remain strongly bound

15-Apr-2019

Modern electronics relies on ultrafast charge motion on ever shorter length scales. Physicists from Regensburg and Gothenburg have now succeeded in resolving a key quantum motion of electrons in atomically thin crystals on the time scale of a single oscillation cycle of light. They directly ...

Physicists watch electron transfer in a single molecule

15-Feb-2019

The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks directly, but rather by their mutual interactions, which are governed by their outer electron shells. Many chemical processes are based on the ...

Feynman Prizes in nanotechnology awarded to Bartosz A. Grzybowski and Franz J. Giessibl

05-Oct-2016

Foresight Institute announced the laureates for the 2016 Foresight Institute Feynman Prizes. Established in 1993, The Feynman prize was named in honor of pioneer physicist Richard Feynman. The prize is given in two categories of nanotechnology, one for experiment and the other for theory. For the ...

A quasiparticle collider

Collision experiments in semiconductors come into reach

13-May-2016

Our standard model of the smallest bits of matter rests upon evidence gathered from particle accelerators and collider experiments. A team of physicists from Regensburg (Germany), Marburg (Germany), and Santa Barbara (USA) have now realized a collider for particles in solids. This fundamentally ...

Slow-motion movies of tiny nanostructures

Researchers developed a novel microscope

07-Oct-2014

Physicists from the University of Regensburg have developed a novel microscope that allows them to record slow-motion movies of tiny nanostructures with groundbreaking time resolution – faster even than a single oscillation cycle of light. With their new microscope they have directly imaged the ...
