Solving the Mystery of Quantum Light in Thin Layers
17-Oct-2019
A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna). It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material ...
Material Scientist wins European Science Slam Championship
Aniruddha Dutta, doctoral student at the Max-Planck-Institut für Eisenforschung, wins championship in Vienna
07-Oct-2019
Aniruddha Dutta, doctoral student at the Max-Planck-Institut für Eisenforschung (MPIE) in Düsseldorf and acting German science slam champion 2018/19, has won the European Science Slam Championship 2019/20 against his competitors from Austria, Switzerland, Sweden, Slovakia, Slovenia, the Czech ...
The fast dance of electron spins
Chemists investigate the interactions of metal complexes and light
07-Oct-2019
Metal complexes show a fascinating behavior in their interactions with light, which for example is utilized in organic light emitting diodes, solar cells, quantum computers, or even in cancer therapy. In many of these applications, the electron spin, a kind of inherent rotation of the electrons, ...
2000 atoms in two places at once
A new record of quantum superposition
30-Sep-2019
The quantum superposition principle has been tested on a scale as never before in a new study by scientists at the University of Vienna in collaboration with the University of Basel. Hot, complex molecules composed of nearly two thousand atoms were brought into a quantum superposition and made to ...
From years to days: Artificial Intelligence speeds up photodynamics simulations
Scientists use deep neural networks to achieve simulations on long time scales
16-Sep-2019
The prediction of molecular reactions triggered by light is to date extremely time-consuming and therefore costly. A team led by Philipp Marquetand from the Faculty of Chemistry at the University of Vienna has now presented a method using artificial neural networks that drastically accelerates ...
Milestones on the Way to the Nuclear Clock
Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition
13-Sep-2019
If you want to build the most accurate clock in the world, you need something that “ticks” very fast and extremely precise. In an atomic clock, electrons are used, which can be switched back and forth between two different states in a very precisely defined way. Even more precise, however, would ...
Single atoms as catalysts
03-Sep-2019
Incorporating individual metal atoms into a surface in the right way allows their chemical behavior to be adapted. This makes new, better catalysts possible. They make our cars more environmentally friendly and they are indispensable for the chemical industry: catalysts make certain chemical ...
A molecular "Trojan Horse"
28-Aug-2019
The research group of Nuno Maulide from the Faculty of Chemistry of the University of Vienna has, in cooperation with the Research Center for Molecular Medicine (CeMM) of the Austrian Academy of Sciences, achieved the synthesis of a potential immunosuppressive agent by modification of a naturally ...
Switching electron properties on and off individually
23-Aug-2019
Properties of complex materials are often determined by the interplay of several electron properties. TU Wien (Vienna) has now succeeded in disentangling this mess. Only at extremely low temperatures does order prevail. At the Vienna University of Technology, materials are cooled to almost ...
How do atoms vibrate in graphene nanostructures?
Innovative new electron spectroscopy technique pushes the limits of Nanospectroscopy for materials design
14-Aug-2019
In order to understand advanced materials like graphene nanostructures and optimize them for devices in nano-, opto- and quantum-technology it is crucial to understand how phonons – the vibration of atoms in solids – influence the materials’ properties. Researchers from the University of Vienna, ...
