A particle like slow light
A particle like slow light
A remarkable discovery was made at TU Wien recently, when particles known as 'Weyl fermions' were discovered in materials with strong interaction between electrons. Just like light particles, they have no mass but nonetheless they move extremely slowly. There was great excitement back in 2015, when it was first possible to measure these 'Weyl fermions' - outlandish, massless particles that had been predicted almost 90 years earlier by German mathematician, physician and philosopher, Hermann Weyl.

Electrical current provides a look inside the lungs
Electrical current provides a look inside the lungs
A new imaging technique, Electrical Impedance Tomography (EIT), will soon be used to monitor important bodily functions. A collaborative project between TU Wien, the Medical University of Vienna and the University of Veterinary Medicine Vienna, has enabled significant progress to be made with this technology.

Magnetic Quantum Objects in a
Magnetic Quantum Objects in a "Nano Egg-Box"
Magnetic quantum objects in superconductors, so-called "fluxons", are particularly suitable for the storage and processing of data bits. Computer circuits based on fluxons could be operated with significantly higher speed and, at the same time, produce much less heat dissipation. Physicists around Wolfgang Lang at the University of Vienna and their colleagues at the Johannes-Kepler-University Linz have now succeeded in producing a "quantum egg-box" with a novel and simple method.

Measured for the first time: direction of light waves changed by quantum effect
Measured for the first time: direction of light waves changed by quantum effect
The 'quantized magneto-electric effect' has been demonstrated for the first time in topological insulators at TU Wien, which is set to open up new and highly accurate methods of measurement. A light wave sent through empty space always oscillates in the same direction. However, certain materials can be used to rotate the direction in which the light is oscillating when placed in a magnetic field.

Quantum Communication: How to Outwit Noise
Quantum Communication: How to Outwit Noise
Nowadays we communicate via radio signals and send electrical pulses through long cables. This could change soon, however: Scientists have been working intensely on developing methods for quantum information transfer. This would enable tap-proof data transfer or, one day, even the linking of quantum computers.
