Graphene: It is all about the toppings
Graphene: It is all about the toppings
To fully exploit the potential of the "wonder material" graphene, it has to be combined with other materials. A new study investigates what is important for this. Graphene consists of a single layer of carbon atoms. Exceptional electronic, thermal, mechanical and optical properties have made graphene one of the most studied materials at the moment.

A new way towards super-fast motion of vortices in superconductors discovered
A new way towards super-fast motion of vortices in superconductors discovered
An international team of scientists from Austria, Germany and Ukraine has found a new superconducting system in which magnetic flux quanta can move at velocities of 10-15 km/s. This opens access to investigations of the rich physics of non-equilibrium collective systems and renders a direct-write Nb-C superconductor as a candidate material for single-photon detectors.

Magnonic nano-fibers opens the way towards new type of computers
Magnetism offers new ways to create more powerful and energy-efficient computers, but the realization of magnetic computing on the nanoscale is a challenging task. A critical advancement in the field of ultralow power computation using magnetic waves is reported by a joint team from Kaiserslautern, Jena and Vienna in the journal Nano Letters.

Laser technology: The Turbulence and the Comb
Laser technology: The Turbulence and the Comb
A particularly well-ordered kind of laser light can be created by turbulence, which is usually responsible for very disordered phenomena. It is a very special kind of light, which can be used for important measurements: so-called frequency combs play a major role in laser research today. While the light of an ordinary laser only has one single, well-defined wavelength, a frequency comb consists of different light frequencies, which are precisely arranged at regular distances, much like the teeth of a comb.

Less gold is Sometimes Better
Less gold is Sometimes Better
Using an ultra-thin gold layer, scientists at TU Wien (Vienna) succeeded in creating an almost optimal infrared absorber. Possible applications range from astrophysics to virus detection. Infrared detectors play an important role in research: many molecules absorb electromagnetic radiation in the infrared range in a very characteristic way.

Superconductivity: It's Hydrogen's Fault
Superconductivity: It’s Hydrogen’s Fault
Nickel is supposed to herald a new age of superconductivity - but this is proving more difficult than expected. Scientists at TU Wien (Vienna) can now explain why. Last summer, a new age for high-temperature superconductivity was proclaimed - the nickel age. It was discovered that there are promising superconductors in a special class of materials, the so-called nickelates, which can conduct electric current without any resistance even at high temperatures.

Cool down fast to advance quantum nanotechnology
Cool down fast to advance quantum nanotechnology
Rapidly cooling magnon particles proves a surprisingly effective way to create an elusive quantum state of matter, called a Bose-Einstein condensate. The discovery can help advance quantum physics research and is a step towards the long-term goal of quantum computing at room temperature. An international team of scientists have found an easy way to trigger an unusual state of matter called a Bose-Einstein condensate.

Antibiotic matter waves
Antibiotic matter waves
One of the central tenets of quantum mechanics is the wave-particle duality. It tells us that even massive objects behave like both particles and waves. A number of previous experiments have shown this for electrons, neutrons, atoms and even large molecules. Quantum theory maintains that this is a universal property of matter.

When Maxwell's demon takes its time
When Maxwell’s demon takes its time
Researchers at the Universities Vienna and Stuttgart have investigated a version of Maxwell's demon embodied by a delayed feedback force acting on a levitated microparticle. They confirmed new fundamental limits that time delay imposes on the demon's actions which are not covered by the standard laws of thermodynamics.

Atomic Fingerprint Identifies Emission Sources of Uranium
Atomic Fingerprint Identifies Emission Sources of Uranium
Uranium is not always the same: depending on whether this chemical element is released by the civil nuclear industry or as fallout from nuclear weapon tests, the ratio of the two anthropogenic, i.e. man-made, uranium isotopes 233U and 236U varies. These results were lately found by an international team grouped around physicists from the University of Vienna and provides a promising new "fingerprint" for the identification of radioactive emission sources.

Cooling magnets with sound
Cooling magnets with sound
Today, most quantum experiments are carried out with the help of light, including those in nanomechanics, where tiny objects are cooled with electromagnetic waves to such an extent that they reveal quantum properties. Now, a team of physicists led by Oriol Romero-Isart at the University of Innsbruck and the Austrian Academy of Sciences is proposing to cool microparticles with sound waves instead.

New quasi-particle discovered: the Pi-ton
New quasi-particle discovered: the Pi-ton
Actually they had been looking for something completely different, but they found a previously unknown quasi-particle: A bound state of two electrons, two holes and light. In physics, there are very different types of particles: Elementary particles are the fundamental building blocks of matter. Other particles, such as atoms, are bound states consisting of several smaller constituents.

How Nature Tells us its Formulas
How Nature Tells us its Formulas
Developing a quantum description for a many-body system is extremely hard. TU Wien (Vienna) and Heidelberg University found a way to obtain quantum theories directly from the experiment. Many of the biggest questions in physics can be answered with the help of quantum field theories: They are needed to describe the dynamics of many interacting particles, and thus they are just as important in solid state physics as in cosmology.

Researchers in Austria use lasers to levitate and cool a glass nanoparticle into the quantum regime. Although it is trapped in a room temperature environment, the particle's motion is solely governed by the laws of quantum physics. The team of scientists from the University of Vienna, the Austrian Academy of Sciences and the Massachusetts Institute of Technology (MIT) published their new study .
