Observing the birth of quasiparticles in real time

The formation of quasiparticles, such as polarons, in a condensed-matter system usually proceeds in an extremely fast way and is very difficult to observe. In Innsbruck, Rudolf Grimm's physics research group, in collaboration ...

Bose-Einstein condensates miscibility properties reveal surprises

Bose-Einstein condensates (BECs) are macroscopic systems that have quantum behaviour, and are useful for exploring fundamental physics. Now researchers at the Gakushuin University and the University of Electro-Communications ...

Titan shines light on high-temperature superconductor pathway

When physicists Georg Bednorz and K. Alex Muller discovered the first high-temperature superconductors in 1986, it didn't take much imagination to envision the potential technological benefits of harnessing such materials.

Novel model illustrates the finer details of nuclear fission

For nearly 80 years, nuclear fission has awaited a description within a microscopic framework. In the first study of its kind, scientists collaborating from the University of Washington, Warsaw University of Technology (Poland), ...

Spintronics for future information technologies: Spin currents in topological insulators controlled

An international team headed by HZB researcher Jaime Sánchez-Barriga has shown how spin-polarised currents can be initiated in a controlled manner within samples of topological insulator material. In addition, they were able ...

Diphoton bump at LHC leads to generation of hundreds of theoretical papers

(Phys.org)—Last year, two teams working at the LHC reported that they had found proton-to-proton collisions that had led to the creation of more photon pairs (with energies of approximately 750 GeV) than was expected, leading ...

Simulation of chiral edge states in a quantum system

Researchers in Florence and Innsbruck have simulated a physical phenomenon in an atomic quantum gas that can also be observed at the edge of some condensed matter systems: chiral currents. The scientists have published the ...

Code speedup strengthens researchers' grasp of neutrons

Neutrons are notoriously slippery subatomic particles. On their own, they break down in a matter of minutes, but within the confines of the atom's nucleus, neutrons are a foundational piece of nearly all known types of matter ...

Controlling interactions between distant qubits

A big part of the burgeoning science of quantum computation is reliably storing and processing information in the form of quantum bits, or qubits. One of the obstacles to this goal is the difficulty of preserving the fragile ...
