New derivation of pi links quantum physics and pure math

In 1655 the English mathematician John Wallis published a book in which he derived a formula for pi as the product of an infinite series of ratios. Now researchers from the University of Rochester, in a surprise discovery, ...

Enlisting symmetry to protect quantum states from disruptions

Symmetry permeates nature, from the radial symmetry of flowers to the left-right symmetry of the human body. As such, it provides a natural way of classifying objects by grouping those that share the same symmetry. This is ...

Smallest vibration sensor in the quantum world

Carbon nanotubes and magnetic molecules are considered building blocks of future nanoelectronic systems. Their electric and mechanical properties play an important role. Researchers of Karlsruhe Institute of Technology and ...

Quantum microscope for living biology

(Phys.org)—A team of Australian scientists has developed a powerful microscope using the laws of quantum mechanics to probe the inner workings of living cells.

Physicists get an up-close look at synthetic quantum materials

(PhysOrg.com) -- Physicists at Harvard University have, for the first time, tracked individual atoms in a gas cooled to extreme temperatures as the particles reorganized into a crystal, a process driven by quantum mechanics. ...
