New research led by an electrical engineer at the University of California, San Diego is aimed at improving lithium (Li) ion batteries through possible new electrode architectures with precise nano-scale designs. The researchers have presented nanowires that block diffusion of lithium across the wire's silicon surface and promote layer-by-layer axial lithiation of the nanowire's germanium core.

Scientists directly observe bound states of elementary magnets in ferromagnetic quantum crystals

more »

Simulating solid state properties with precisely controlled quantum systems is an important goal of the Quantum Many-Body Systems Division at MPQ. Now the team around Professor Immanuel Bloch (Chair for Experimental Physics at the Ludwig-Maximilians-Universität Munich and Director at MPQ) has come again a step closer to it – to be precise, to the understanding of processes in ferromagnetic solid state crystals in which elementary excitations, so-called magnons, can emerge. About 80 years ago the German physicist Hans Bethe deduced from a theoretical model that in one-dimensional ferromagnets two of those elementary magnetic excitations can form a bound state. Like two tiny bar magnets, two atoms can stick together and form a new particle that propagates in the crystal. The MPQ team has now succeeded to observe these most elementary mobile magnetic domains, the two-magnon states, directly and to resolve their dynamics with time-resolved measurements. This study complements conventional spectroscopy in solid state crystals which yields information on momentum and frequency of the magnetic excitations. Bound states of excitations can influence the thermal conductance properties of low-dimensional ferromagnets or the propagation speed of quantum information in magnetic wires.

Herschel throws new light on oldest cosmic light

more »

(Phys.org) —Cosmologists have achieved a first detection of a long-sought component in the Cosmic Microwave Background (CMB). This component, known as B-mode polarisation, is caused by gravitational lensing, the bending of light by massive structures as it travels across the Universe. The result is based on the combination of data from the South Pole Telescope and ESA's Herschel Space Observatory. This detection is a milestone along the way to the possible discovery of another kind of B-mode signal in the polarised CMB - a signal produced by gravitational waves less than a second after the Universe began.

(Phys.org) —Now approaching its 10th anniversary, NASA's Spitzer Space Telescope has evolved into a premier observatory for an endeavor not envisioned in its original design: the study of worlds around other stars, called exoplanets. While the engineers and scientists who built Spitzer did not have this goal in mind, their visionary work made this unexpected capability possible. Thanks to the extraordinary stability of its design and a series of subsequent engineering reworks, the space telescope now has observational powers far beyond its original limits and expectations.

On the road to fault-tolerant quantum computing: High temperature superconductivity in a toplogical insulator

Reliable quantum computing would make it possible to solve certain types of extremely complex technological problems millions of times faster than today's most powerful supercomputers. Other types of problems that quantum computing could tackle would not even be feasible with today's fastest machines. The key word is "reliable." If the enormous potential of quantum computing is to be fully realized, scientists must learn to create "fault-tolerant" quantum computers. A small but important step toward this goal has been achieved by an international collaboration of researchers from China's Tsinghua University and the DOE's Lawrence Berkeley National Laboratory (Berkeley Lab) working at the Advanced Light Source (ALS).

Scientists observe competing quantum effects on the kinetic energy of protons in water

more »

(Phys.org) —Quantum mechanics plays an important role in determining the structure and dynamics of water, down to the level of the atomic nuclei. Sometimes, nuclear quantum effects (NQEs) along different molecular axes compete with each other and partially cancel each other out. This phenomenon is thought to play a role in determining the melting and boiling temperatures of water. Now for the first time, scientists have experimentally observed that two large components of NQEs partially cancel each other out to result in a small net effect on the melting and boiling points of water.

ALMA discovers large 'hot' cocoon around a small baby star

more »

International research team, led by researcher at the University of Electro-Communication observed an infrared dark cloud G34.43+00.24 MM3 with ALMA and discovered a baby star surrounded by a large hot cloud. This hot cloud is about ten times larger than those found around typical solar-mass baby stars. Hot molecular clouds around new-born stars are called "Hot Cores" and have temperature of – 160 degrees Celsius, 100 degrees hotter than normal molecular clouds. The large size of the hot core discovered by ALMA shows that much more energy is emitted from the central baby star than typical solar-mass young stars. This may be due to the higher mass infall rate, or multiplicity of the central baby star. This result indicates a large diversity in the star formation process.

Building bridges between nanowires

more »

Place a layer of gold only a few atoms high on a surface bed of germanium, apply heat to it, and wires will form of themselves. Gold-induced wires is what Mocking prefers to call them. Not 'gold wires', as the wires are not made solely out of gold atoms but also contain germanium. They are no more than a few atoms in height and are separated by no more than 1.6 nanometres (a nanometre is one millionth of a millimetre). Nanotechnologists bridge this small 'gap' with a copper-phthalocyanine molecule. A perfect fit. This molecule was found to be able to rotate if the electrons coursing towards it possess sufficient energy, allowing it to function as a switch. What's more: the copper atom of this molecule floats in the vacuum above the gap - fully detached. This might allow researchers to identify new properties the nanowires may possess.
