In a scrambled Rubiks cube, colorful squares clash without order. As pieces click into place in the hands of a skilled puzzle solver, the individual characters of squares dissolve as solid faces of uniform color emerge.
In the same way, barium copper silicate-also known as Han Purple, a vivid pigment used in ancient China-transforms from a nonmagnetic, disordered insulator into a magnetic, ordered condensate under conditions of extreme cold and high magnetic field. The components that click into place to form an entirely new phase are the electron orientations of atoms, or spins, described by their quantum state as up or down.
Now, scientists at Stanford, Los Alamos National Laboratory and the Institute for Solid State Physics (University of Tokyo) have discovered that at the abrupt lowest temperature transition at which the silicate enters a new state-called the quantum critical point-the three-dimensional material loses a dimension to form a Flatland, of sorts. Just as in the 1884 novella Flatland that posited a planar world, the spins strongly interact only in two dimensions. Effects from the third dimension are negligible. Their work appears in the June 1 issue of Nature.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
