TU Wien (German: Technische Universität Wien, also TUW and former, but still commonly used, Vienna University of Technology) is one of the major universities in Vienna. The university has received extensive international and domestic recognition in teaching as well as in research, and it is a highly esteemed partner of innovation oriented enterprises. It currently has about 28,100 students (29% women), eight faculties and about 5,000 staff members (3,800 academics). The university's teaching and research is focused on engineering, computer science, and natural sciences.

Curved spacetime in a quantum simulator

“New techniques can answer questions that were previously inaccessible experimentally - including questions about the relationship between quantum mechanics and relativity. The theory of relativity works well when you want to explain cosmic-scale phenomena - such as the gravitational waves created when …

Scale separation: breaking down unsolvable problems into solvable ones

“Exact solutions are often impossible in materials physics. In an international research cooperation involving TU Wien and Saitama University in Japan a technique has now been developed to make unsolvable quantum calculations solvable on certain scales. In physics, one often …

Absolute Zero in the Quantum Computer

“Erasing data perfectly and reaching the lowest possible temperature – those two things seem to be completely different, but they are closely intertwined. At TU Wien, a quantum formulation has now been found for the third law of thermodynamics. The absolute …

New invention: The oxygen-ion battery

“A new type of battery has been invented at TU Wien (Vienna): The oxygen-ion battery can be extremely durable, does not require rare elements and solves the problem of fire hazards. Lithium-ion batteries are ubiquitous today - from electric cars to …

Chaos gives the quantum world a temperature

“A single particle has no temperature. It has a certain energy or a certain speed — but it is not possible to translate that into a temperature. Only when dealing with random velocity distributions of many particles, a well-defined temperature emerges …

Faster and more Efficient Computer Chips Thanks to Germanium

“TU Wien (Vienna) has succeeded in making a new type of material usable for chip technology. This enables faster, more efficient computers and new types of quantum devices. Our current chip technology is largely based on silicon. Only in very …

A Molecule of Light and Matter

“Using light, atoms can be made to attract each other. A team from Vienna and Innsbruck was able to measure this binding state of light and matter for the first time. A very special bonding state between atoms has been …

Quantum Physics Sets a Speed Limit to Electronics

“Semiconductor electronics is getting faster and faster - but at some point, physics no longer permits any increase. The shortest possible time scale of optoelectronic phenomena has now been investigated. How fast can electronics be? When computer chips work with ever …

Photocatalysis: the Nano-Sponge Revolution

“Creating a sponge-like hole structure on the nanometre scale that allows small molecules to pass through, record-breaking chemical reactivity was achieved. Catalysts are often solid materials whose surface comes into contact with gases or liquids, thereby enabling certain chemical reactions …

2D material in three dimensions

“How do you integrate as much as possible of the 2D material graphene into a limited space? By producing it not on a flat surface, but on a 3D nanostructure. The carbon material graphene has no well-defined thickness, it merely …
