View ArticleResearch show mechanism behind wear at the atomic scale
(Phys.org)—Wear is a fact of life. As surfaces rub against one another, they break down and lose their original shape. With less material to start with and functionality that often depends critically...
View ArticleOn the origins of the Schrodinger equation
(Phys.org) —One of the cornerstones of quantum physics is the Schrödinger equation, which describes what a system of quantum objects such as atoms and subatomic particles will do in the future based on...
View ArticleImproving measurements by reducing quantum noise
If you want to measure something very precisely, such as slight variations of a length, then you are very likely to use light waves. However, many effects, such as variations of gravity, or surface...

(Phys.org) —Researchers at the University of Strathclyde in Glasgow have identified twelve easily retrievable objects among the population of near earth objects (NEOs). In their paper published this...
View ArticleAtoms can be in two places at the same time
Can a penalty kick simultaneously score a goal and miss? For very small objects, at least, this is possible: according to the predictions of quantum mechanics, microscopic objects can take different...
View ArticleResearchers describe the wavefunction of Schroedinger's cat
Schrödinger's cat highlights a long-standing dilemma in quantum mechanics: is the cat really alive and dead, or is the weirdness just in our head?
View ArticleTeam demonstrates wavelike quantum behaviour of polariton condensate on...
For the first time, the wavelike behaviour of a room-temperature polariton condensate has been demonstrated in the laboratory on a macroscopic length scale. This significant development in the...
