Bridges in Austria often exceed expectations
Bridges in Austria often exceed expectations
Assessing old bridges using modern standards is no mean feat. Studies conducted by TU Wien show that many bridges are actually significantly more stable than might be expected, often rendering costly restoration work unnecessary. Deciding which bridges need to be restored in the near future and which are still in good condition can have extremely expensive repercussions.

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.

Testing Quantum Field Theory in a Quantum Simulator
Testing Quantum Field Theory in a Quantum Simulator
A new way to characterize many-particle quantum systems has been presented in the journal "Nature" by TU Wien (Vienna) and Heidelberg University. Quantum simulators can now be used to take a deeper look at previously unanswered questions. What happened right after the beginning of the universe? How can we understand the structure of quantum materials' How does the Higgs-Mechanism work? Such fundamental questions can only be answered using quantum field theories.

In both love and war, alligators signal size by bellowing
In both love and war, alligators signal size by bellowing
American alligators produce loud, low-frequency vocalizations called "bellows". Cognitive biologists at the University of Vienna, Stephan Reber and Tecumseh Fitch, investigated these vocalizations and found that they reveal the caller's body size. Alligators can use this information to avoid unpromising contests for mates and breeding areas.

Unbreakable quantum entanglement
Unbreakable quantum entanglement
Einstein's "spooky action at a distance" persists even at high accelerations, researchers of the Austrian Academy of Sciences and the University of Vienna were able to show in a new experiment. A source of entangled photon pairs was exposed to massive stress: The photons' entanglement survived the drop in a fall tower as well as 30 times the Earth's gravitational acceleration in a centrifuge.

Natural gas facilities with no CO2 emissions
Natural gas facilities with no CO2 emissions
How can we burn natural gas without releasing CO2 into the air? This feat is achieved using a special combustion method that TU Wien has been researching for years: chemical looping combustion (CLC). In this process, CO2 can be isolated during combustion without having to use any additional energy, which means it can then go on to be stored.

Chemically tailored Graphene
Chemically tailored Graphene
Graphene is considered as one of the most promising new materials. However, the systematic insertion of chemically bound atoms and molecules to control its properties is still a major challenge. Now, for the first time, scientists of the Friedrich-Alexander-Universität Erlangen-Nürnberg, the University of Vienna, the Freie Universität Berlin and the University Yachay Tech in Ecuador succeeded in precisely verifying the spectral fingerprint of such compounds in both theory and experiment.

Hand scanner measures bitumen quality
Hand scanner measures bitumen quality
Asphalt does not last forever. At some point, it ages and starts to crumble. This has to do with the bitumen, the sticky binding agent, which holds and keeps the rock content in the asphalt. Bitumen is a petroleum product consisting of several organic components, which undergo a chemical change over time.

Unveiling nonlocal correlations in natural systems
Nonlocal correlations are a quantum phenomenon that constitute a stronger form of correlations than quantum entanglement. Researchers at MPQ, ICFO, University of Innsbruck and the Center for Theoretical Physics PAS have developed a new method to show that the low energy states of some physical spin Hamiltonians can exhibit these nonlocal correlations.

Microprocessors based on a layer of just three atoms
Microprocessors based on a layer of just three atoms
Two-dimensional materials, or 2D materials for short, are extremely versatile, although - or often more precisely because - they are made up of just one or a few layers of atoms. Graphene is the best-known 2D material. Molybdenum disulphide (a layer consisting of molybdenum and sulphur atoms that is three-atoms thick) also falls in this category, although, unlike graphene, it has semiconductor properties.
