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.

The Unfoldable Bridge
The Unfoldable Bridge
A world premiere in Austria: The new bridge construction technology which was developed at TU Wien has now been successfully applied by ASFINAG during the construction of the Fürstenfeld Motorway There are many different methods for erecting bridges - but the new technique developed by TU Wien, the balanced lowering method, is quite spectacular: the bridge is not built horizontally, as would normally be case, but erected in a vertical position and then rotated into the horizontal position.

Human brain asymmetry is not unique, but its variability is
Human brain asymmetry is not unique, but its variability is
A new analysis suggests that an asymmetry pattern shared with great apes was adapted for lateralized, uniquely human cognitive abilities The left and right side of the brain are involved in different tasks. This functional lateralization and associated brain asymmetry are well documented in humans, but little is known about brain asymmetry in our closest living relatives, the great apes.

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.

Dancing Matter: New form of movement of cyclic macromolecules discovered
Physicists show unique polymer behavior using computer simulations Employing a computer simulation, physicists Maximilian Liebetreu and Christos Likos have shown a unique dynamic behavior of cyclic polymers. Their motion can be distinguished into phases, and the scientists were able to observe the so-called "inflation phase" for the first time.

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.

A Quantum of Solid
A Quantum of Solid
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 .

The paint testing machine
The paint testing machine
How can you prevent cracks from forming after painting? TU Wien has recently patented two new measuring processes that show which paint is best. It's a familiar problem for anyone who has renovated a house or flat: no building is a perfectly rigid body. Walls and ceilings can move slightly over time, which often leads to cracks in the paint on the walls.

How to Take a Picture of a Light Pulse
Until now, complex experimental equipment was required to measure the shape of a light pulse. A team from TU Wien (Vienna), MPI Garching and LMU Munich has now made this much easier. Today, modern lasers can generate extremely short light pulses, which can be used for a wide range of applications from investigating materials to medical diagnostics.

A new form of glass through molecular entanglement
Physicists at the University of Vienna in collaboration with the Max Planck Institute for Polymer Research have discovered a new type of glass formed by long, cyclic molecules. The scientists successfully demonstrated that by making parts of the rings more mobile, the rings become more strongly entangled and the molecular fluid glassifies.
