Rutgers researchers ’rewrite the book’ in quantum statistical physics

13.02.2006


An important part of the decades-old assumption thought to be essential for quantum statistical physics is being challenged by researchers at Rutgers, The State University of New Jersey, and colleagues in Germany and Italy.

In a journal article to be published in Physical Review Letters and now available online, the researchers show that it is not necessary to assume that large collections of atomic particles are in a random state in order to derive a mathematical formula that conveys that smaller collections of those particles are indeed random. While their proof is unlikely to change any of today’s high-tech products and processes, it could nonetheless lead to rewrites of tomorrow’s physics textbooks.

For decades, physicists believed that an assumption of randomness accounts for the canonical distribution formula at the heart of statistical mechanics, a field that helps scientists understand the structure and properties of materials. Randomness remains a necessary foundation to derive this formula for systems governed by the principles of classical mechanics. But the basic constituents of materials reside at the atomic and subatomic levels, where the principles of quantum mechanics take hold. The researchers have found that for quantum systems the situation is quite different than physicists had believed.



"What we have found is so simple that it is surprising that it was not discovered long ago," said Sheldon Goldstein, professor of mathematics and physics at Rutgers and one of the paper’s four authors. "More surprising still is the fact that Erwin Schroedinger, one of the founders of quantum mechanics, had the essential idea more than fifty years ago, and this was entirely unappreciated."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
