Electric Skyrmions Charge Ahead for Next-Generation Data Storage

Lawrence Berkeley National Laboratory

A team of researchers led by Berkeley Lab has observed chirality for the first time in polar skyrmions in a material with reversible electrical properties – a combination that could lead to more powerful data storage devices that continue to hold information, even after they’ve been turned off.

Quantum simulation more stable than expected

University of Innsbruck

Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. "A particularly promising application is the solution of quantum many-body problems utilizing the concept of digital quantum simulation", says Markus Heyl from Max Planck Institute for the Physics of Complex in Dresden, Germany.

Squeezed nanocrystals: A new model predicts their shape when blanketed under graphene

Ames Laboratory

In a collaboration between the U.S. Department of Energy’s Ames Laboratory and Northeastern University, scientists have developed a model for predicting the shape of metal nanocrystals or “islands” sandwiched between or below two-dimensional (2D) materials such as graphene. The advance moves 2D quantum materials a step closer to applications in electronics.

UCI scientists are first to observe and image all-important molecular vibrations

University of California, Irvine

Irvine, Calif., April 3, 2019 – By focusing light down to the size of an atom, scientists at the University of California, Irvine have produced the first images of a molecule’s normal modes of vibration – the internal motions that drive the chemistry of all things, including the function of living cells. In a study in Nature, researchers at UCI’s Center for Chemistry at the Space-Time Limit describe how they positioned the atomically terminated silver tip of a scanning tunneling microscope mere ängstroms from its target: a cobalt-based porphyrin molecule affixed to a copper platform.
