Physics Week in Review: February 25, 2017

Physics lost one of its brightest lights this week: R.I.P. Mildred Dresselhaus: In five decades at MIT, the “Queen of Carbon Science” was a tireless champion of gender equity in science and engineering. Physicists Uncover Geometric ‘Theory Space’: A decades-old...

Nanoparticles give super-resolution microscopy a boost

Amplified stimulated emission allows low-illumination applications

One minute with Keith Coiley, data center specialist

Every day is different for Keith Coiley, who will cheerfully help you manage almost any task that comes his way.

The ancient art of kirigami is inspiring a new class of materials

Origami-inspired materials use folds in materials to embed powerful functionality. However, all that folding can be pretty labor intensive. Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) are drawing material inspiration from another ancient Japanese paper craft—kirigami.

Focus: Atomic Impersonator

Author(s): Michael Schirber Calculations show that a carefully engineered laser pulse can induce an atom to emit light as if it were a different atom. [Physics 10, 21] Published Fri Feb 24, 2017

Researchers use holography to improve nanophotonic circuits

Nanophotonic circuits, tiny chips which filter and steer light, suffer from small random variations which degrade the transmission of light. Researchers have now found a way to compensate those variations, which may lead to energy savings in datacenters and computer equipment. Show More Summary

Crumpled Mylar found to hold memory of how long it was crumpled

(Phys.org)—A small team of researchers at Harvard University has found that crumpled sheets of Mylar hold a memory of how long they were crumpled. In their paper published in the journal Physical Review Letters, the group describes experiments...Show More Summary

Researchers develop surprising technique for ultrashort laser pulses

Pulse lasers built entirely on optical fibers are increasingly used by industry. Optical scientists from the Warsaw Laser Centre of the Institute of Physical Chemistry of the Polish Academy of Sciences and the Faculty of Physics of the...Show More Summary

Nuclear energy may come from the sea

Uranium extracted from the sea could provide centuries of power

Synopsis: Drops Shatter in the Cold

High-speed video and modeling reveal the conditions under which water drops explode when they’re frozen from the outside in. [Physics] Published Thu Feb 23, 2017

Physicists Uncover Geometric ‘Theory Space’

A decades-old method called the “bootstrap” is enabling new discoveries about the geometry underlying all quantum theories.

Instrument finds new earthly purpose

Detectors long used to look at the cosmos are now part of X-ray experiments here on earth. Modern cosmology experiments—such as the BICEP instruments and the Keck Array in Antarctica—rely on superconducting photon detectors to capture...Show More Summary

Scientists solve puzzle of turning graphite into diamond

(Phys.org)—Researchers have finally answered a question that has eluded scientists for years: when exposed to moderately high pressures, why does graphite turn into hexagonal diamond (also called lonsdaleite) and not the more familiar cubic diamond, as predicted by theory?

Synopsis: Revealing a Hidden Spin Polarization

Photoemission spectroscopy has detected two different populations of spin-polarized electrons that are “hidden” within a layered, graphene-like material. [Physics] Published Wed Feb 22, 2017

Getting the inside story on products with computed tomography

It is often the case that a valuable new industrial capability brings with it a whole new set of challenges for measurement science—and thus, inevitably, for NIST.
