New paths into the world of quasiparticles

Quasiparticles can be used to explain physical phenomena in solid bodies even though they are not actual physical particles. Physicists in Innsbruck have now realized quasiparticles in a quantum system and observed quantum ...

Experimentally testing nonlocality in many-body systems

In a recent study published in Science, researchers at ICFO construct multipartite Bell inequalities built from the easiest-to-measure quantities, the two-body correlators, which are capable of revealing nonlocality in many-body ...

Quantum correlations make you never fail a test again

(Phys.org) —In the burgeoning field of quantum metrology, quantum effects are exploited to improve the precision when measuring a variety of parameters, such as phase, frequency, and magnetic fields. A main goal of this ...

Rotational X-ray tracking uncovers hidden motion at the nanoscale

Over the past two decades or so, there has been increasing interest and development in measuring slow dynamics in disordered systems at the nanoscale, brought about in part from a demand for advancements in the food and consumer ...

New way to measure electron pair interactions

Shoot a beam of light or particles at certain special materials and you will liberate electrons—pairs of them—a phenomenon known as "electron pair emission," which can reveal fundamental properties of the solid and reveal ...

IQ boost for web intelligence

Views and opinions can now be filtered out of very large volumes of online text with greater accuracy than ever before. Thanks to an automatic method developed at MODUL University Vienna, ambiguous terms in online content ...
