'Field patterns' as a new mathematical object

University of Utah mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory, called "field patterns," ...

Bohr's quantum theory revised

Niels Bohr's atomic model was utterly revolutionary when it was presented in 1913. Although it is still taught in schools, it became obsolete decades ago. However, its creator also developed a much wider-ranging and less ...

Quantum RAM: Modelling the big questions with the very small

When it comes to studying transportation systems, stock markets and the weather, quantum mechanics is probably the last thing to come to mind. However, scientists at Australia's Griffith University and Singapore's Nanyang ...

Quantum phase transition observed for the first time

A group of scientists led by Johannes Fink from the Institute of Science and Technology Austria (IST Austria) reported the first experimental observation of a first-order phase transition in a dissipative quantum system. ...

Quantum membranes for ultraprecise mechanical measurements

Quantum mechanics dictates sensitivity limits in the measurements of displacement, velocity and acceleration. A recent experiment at the Niels Bohr Institute probes these limits, analyzing how quantum fluctuations set a sensor ...

Exotic insulator may hold clue to key mystery of modern physics

Experiments using laser light and pieces of gray material the size of fingernail clippings may offer clues to a fundamental scientific riddle: what is the relationship between the everyday world of classical physics and the ...
