The quantum refrigerator

Computer simulations show how quantum fields could be used to break low-temperature records

30-Jul-2021 - At first glance, heat and cold don't have much to do with quantum physics. A single atom is neither hot nor cold. Temperature can only be defined for objects that consist of many particles. But at TU Wien, in collaboration with Freie Universität Berlin, Nanyang Technological University in ...

Neural Hardware for Image Recognition in Nanoseconds

Ultra-fast image sensor with a built-in neural network can be trained to recognize certain objects

06-Mar-2020 - Automatic image recognition is widely used today: There are computer programs that can reliably diagnose skin cancer, navigate self-driving cars, or control robots. Up to now, all this has been based on the evaluation of image data as delivered by normal cameras - and that is time-consuming. ...

With great power comes great laser science

Scientists found a way to compress ultrashort laser pulses, increasing its peak power to half a terawatt

15-Sep-2016 - It is a very unusual kind of laser: researchers at the photonics institute at TU Wien (Vienna) have built a device which emits ultrashort flashes of infrared light with extremely high energy. “It is very hard to combine these three properties – long infrared wavelength, short duration and high ...

How a cold gets into cells

21-Jun-2016 - Viruses smuggle their genetic material into our cells. How this actually works is currently being investigated at TU Wien (Vienna) using a new combination of analysis methods. Cold viruses cause us irritation by penetrating into our cells and transporting their RNA into the cytoplasma of the ...

New material promises faster electronics

30-Jan-2013 - High hopes are pinned on this new material: Graphene, a honeycomb-like carbon structure, made of only one layer of atoms, exhibits remarkable properties. In 2010, the Nobel Prize was awarded for the discovery of graphene and its behavior. At the Photonics Institute at the TU Vienna, the ...

Nano-hillocks: Of mountains and craters

04-Oct-2012 - In the field of nanotechnology, electrically-charged particles are frequently used as tools for surface modification. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the TU Vienna were at last able to reconcile important issues concerning the effects of highly charged ions on ...

Are you certain, Mr. Heisenberg?

Measurements at the Vienna University of Technology deepen our understanding of quantum uncertainty

23-Jan-2012 - Heisenberg's Uncertainty principle is arguably one of the most famous foundations of quantum physics. It says that not all properties of a quantum particle can be measured with unlimited accuracy. Until now, this has often been justified by the notion that every measurement necessarily has to ...

International First: Gas-phase Carbonic Acid Isolated

18-Jan-2011 - A team of chemists headed by Thomas Loerting from the University of Innsbruck and Hinrich Grothe from the Vienna University of Technology (TU Wien) in Austria have prepared and isolated gas-phase carbonic acid and have succeeded in characterizing the gas-phase molecules by using infrared ...

Computer model for osteoporosis diagnostics

24-Jan-2008 - Osteoporosis, a common age-related disease, is being investigated by a group of biomechanical engineers at Vienna University of Technology (TU Vienna). In the frame of a clinical study, the evolution of vertebral bone density was monitored in patients. The researchers developed a simulation ...
