MIT physicists have invented a new technique to cool atoms into condensates, which is faster than the conventional method and conserves a large fraction of the original atoms. The team used a new process of laser cooling to cool a cloud of rubidium atoms all the way from room temperature to 1 microkelvin, or less than one-millionth of a degree above absolute zero.
Due to their unique properties, carbon nanotubes would be ideal for numerous applications, but to date they cannot be combined adequately with other materials, or they lose their beneficial properties. Scientists from Kiel University and the University of Trento have developed an alternative method of combining, so they retain their characteristic properties. As such, they 'felt' the thread-like tubes into a stable 3-D network. Their research results have been published in Nature Communications.
Researchers have discovered that dense ensembles of quantum spins can be created in diamond with high resolution using an electron microscopes, paving the way for enhanced sensors and resources for quantum technologies. This work demonstrates an improvement in the densities of Nitrogen-Vacancy (NV) centers in a variety of diamond types, foreshadowing future improvements in the sensitivity of diamond magnetic measurements, as well as promising directions in the study of solid state physics and quantum information theory.
The Collaborative Research Centre CRC 1214 at the University of Konstanz has developed a method for synthesizing Europium (II) oxide nanoparticles -- a ferromagnetic semiconductor that is relevant for data storage and data transport.
New research on oxygen and iron chemistry under the extreme conditions found deep inside the Earth could explain a longstanding seismic mystery called ultralow velocity zones. Published in Nature, the findings could have far-reaching implications on our understanding of Earth's geologic history, including life-altering events such as the Great Oxygenation Event, which occurred 2.4 billion years ago.
UCSB physicists open the door to the first direct measurement of Berry curvature in solid matter.
Innovative technologies developed by researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory recently earned several R&D 100 Awards.
A research team led by The University of Texas at Austin Jackson School of Geosciences took to the lab to recreate the magmatic melt that once formed the lunar surface and uncovered new insights on how the modern moonscape came to be.
Research from MIT reveals the best way to make metal particles stick to a surface in a spray-coating process. Surprisingly, melting hurts rather than helps.
The discovery of nanoscale changes deep inside hybrid perovskites could shed light on developing low-cost, high-efficiency solar cells. Using X-ray beams and lasers, a team of researchers led by the University of California San Diego discovered how the movement of ions in hybrid perovskites causes certain regions within the material to become better solar cells than other parts.
