Clarified at last: the physics of popping champagne
Clarified at last: the physics of popping champagne
When you uncork a bottle of champagne, complex supersonic phenomena occur. Scientists at TU Wien have now been able to calculate exactly what happens for the first time. It sounds like a simple, well-known everyday phenomenon: there is high pressure in a champagne bottle, the stopper is driven outwards by the compressed gas in the bottle and flies away with a powerful pop.

Unconventional magnets: stress reduces frustration
Unconventional magnets: stress reduces frustration
An international research team recently demonstrated how magnetism can be actively changed by pressure. Magnetism occurs depending on how electrons behave. For example, the elementary particles can generate an electric current with their charge and thereby induce a magnetic field. However, magnetism can also arise through the collective alignment of the magnetic moments (spins) in a material.

Strangely 'quiet' current in strange metal
Strangely ’quiet’ current in strange metal
What happens when electric current flows through a "strange metal"- TU Wien (Vienna) and Rice University (Texas) show: The established picture of electrons and "quasi-electrons" collapses. At first glance, it all sounds so simple: there are electrons in a cable, and when we apply a voltage, the electrons dash from one side of the cable to the other, and an electric current flows.

Limits for quantum computers: perfect clocks are impossible
Limits for quantum computers: perfect clocks are impossible
It is becoming increasingly possible to carry out calculations with quantum computers. However, calculations by TU Wien show that there are fundamental limits - namely the quality of the clock used . There are different ideas on how to build quantum computers. But they all have one thing in common: you use a quantum physical system - for example individual atoms - and change their state by exposing them to very specific forces for a very specific time.

Two Conductors of a Chemical Reaction
Two Conductors of a Chemical Reaction
For the first time, researchers at TU Wien have successfully observed the operating principle of so-called promoters in a catalytic reaction in real-time. These promoters play an important role in technology, but so far there is only limited understanding of how they work. Catalysts are essential for numerous chemical technologies, ranging from exhaust gas purification to the production of valuable chemicals and energy carriers.

Crystal structure: forecasts you can trust
An international team from science and industry has revolutionized the modelling and prediction of free energy in crystals. Their work on the new TRHu(ST) method, published in Nature , shows that the stability of crystal forms can be predicted reliably and cost-effectively under real temperature and humidity conditions.

Interacting polarons
Interacting polarons
In physics, the complex processes in solids are often described in terms of quasiparticles. In ultracold quantum gases, these quasiparticles can be reproduced and studied. Now, for the first time, Innsbruck scientists led by Rudolf Grimm have been able to observe in experiments how Fermi polarons - a special type of quasiparticle - can interact with each other.

Golden future for thermoelectrics
Researchers at TU Wien discover excellent thermoelectric properties of nickel-gold alloys. These can be used to efficiently convert heat into electrical energy. Thermoelectrics enable the direct conversion of heat into electrical energy - and vice versa. This makes them interesting for a range of technological applications.

The Wild Boar Paradox - Finally Solved
The Wild Boar Paradox - Finally Solved
Decades after the Chernobyl nuclear accident, wild boar meat is still surprisingly radioactive. The solution to the riddle: an important other cause had been overlooked. The Chernobyl nuclear accident in 1986 had a major impact on the forest ecosystem in Central Europe. After the accident, the consumption of mushrooms was discouraged because of the high radioactive contamination, and the meat of wild animals was also severely affected for several years.

Graphene: Perfection is futile
Graphene: Perfection is futile
The carbon material graphene has excellent electronic properties. But are they also stable enough to be useful in practice? Calculations from TU Wien say: Yes. Nothing in the world is perfect. This is also true in materials research. In computer simulations, one often represents a system in a highly idealized way; for example, one calculates the properties that an absolutely perfect crystal would have.

Magnonic computing: Faster spin waves could make novel computing systems possible
Breakthrough in research on novel energy-efficient computer Research is underway around the world to find alternatives to our current electronic computing technology, as great, electron-based systems have limitations. A new way of transmitting information is emerging from the field of magnonics: instead of electron exchange, the waves generated in magnetic media could be used for transmission, but magnonics-based computing has been (too) slow to date.
