1. Researchers generate, for the first time, a vortex beam of atoms and molecules00:44[−]
Категория(?)  
Vortices may conjure a mental image of whirlpools and tornadoes—spinning bodies of water and air—but they can also exist on much smaller scales. In a new study published in Science, researchers from the Weizmann Institute of Science, together with collaborators from the Technion-Israel Institute of Technology and Tel Aviv University, have created, for the first time, vortices made of a single atom. These vortices could help answer fundamental questions about the inner workings of the subatomic world and be used to enhance a variety of technologies—for example, by providing new capabilities for atomic microscopes.

An international team led by EPFL scientists, has unveiled a unique quantum-mechanical interaction between electrons and topological defects in layered materials that has only been observed in engineered atomic thin layers. The phenomenon can be reproduced by the native defects of lab grown large crystals, making future investigation of Kondo systems and quantum electronic devices more accessible.

10. Three-body interactions bring egoists into the collective comfort zone—even penguinsВт, 30 ноя[−]
Категория(?)  
A research team from Heinrich Heine University D?sseldorf (HHU) has worked together with TU Darmstadt and an MPI based in Garching to examine the group dynamics of communicating active particles. These particles are consistently focused on self-optimisation. By always endeavoring to maintain their own personal comfort, they also help the other group members. As the researchers describe in the journal Proceedings of the National Academy of Sciences, such self-optimisation is a common multi-body phenomenon which can occur for penguins and bacteria.

Категория(?)  
Have you ever thought about not voting because your preferred candidate's victory seems assured? New Cornell research uses mathematical modeling to show that type of thinking can have the opposite effect, resulting in the election of politicians who do not represent the preferences of the electorate as a whole.

12. 3D laser nanoprinters become compactВт, 30 ноя[−]
Категория(?)  
Lasers in conventional laser printers for paper printouts are very small. 3D laser printers for 3-dimensional microstructures and nanostructures, by contrast, have required big and expensive laser systems so far. Researchers of Karlsruhe Institute of Technology (KIT) and the Heidelberg University now use another process for this purpose. Two-step absorption works with inexpensive and small, blue laser diodes. As a result, much smaller printers can be used. The work is reported in Nature Photonics.

14. Researchers propose a simpler design for quantum computersПн, 29 ноя[−]
Категория(?)  
Today's quantum computers are complicated to build, difficult to scale up, and require temperatures colder than interstellar space to operate. These challenges have led researchers to explore the possibility of building quantum computers that work using photons—particles of light. Photons can easily carry information from one place to another, and photonic quantum computers can operate at room temperature, so this approach is promising. However, although people have successfully created individual quantum "logic gates" for photons, it's challenging to construct large numbers of gates and connect them in a reliable fashion to perform complex calculations.

The breakthrough could prove pivotal in future quantum key distribution networks or distributed quantum computing.

19. Breaking the symmetry of sound waves allows the sound to be directed to a certain placeПн, 29 ноя[−]
Категория(?)  
Research undertaken by the Universidad Carlos III de Madrid (UC3M) has concluded that sound can be directed to a certain place if the sound waves' symmetry is broken. In order to carry out this work, recently published in the journal Nature, researchers used the whispering gallery phenomenon, a circular, vaulted room in which you can hear what is being said in a specific part of the room from anywhere, even if it is being whispered.

20. Nondestructive testing of optical fiber diametersПн, 29 ноя[−]
Категория(?)  
The increased use of optical fiber has seen a greater focus on the precise control and measurement of its diameter. That is due to the diameter being vital for a wide range of fields, from high-speed optical communication to ultra-high sensitivity sensing. Handling optical fiber before measurement can damage the fiber permanently, particularly when multiple-point measurements are needed.

22. Programmable interaction between quantum magnetsПн, 29 ноя[−]
Категория(?)  
The forces between particles, atoms, molecules, or even macroscopic objects like magnets are determined by the interactions of nature. For example, two closely lying bar magnets realign themselves under the influence of magnetic forces. A team led by Prof. Dr. Matthias Weidem?ller and Dr. Gerhard Z?rn at the Center for Quantum Dynamics of Heidelberg University has now succeeded in its aim to change not only the strength but also the nature of the interaction between microscopic quantum magnets, known as spins. Instead of falling into a state of complete disorder, the especially prepared magnets can maintain their original orientation for a long period. With these findings, the Heidelberg physicists have successfully demonstrated a programmable control of spin interactions in isolated quantum systems.

24. Doing photon upconversion a solid: Crystals that convert light to more useful wavelengthsПт, 26 ноя[−]
Категория(?)  
Solid-solution organic crystals have been brought into the quest for superior photon upconversion materials, which transform presently wasted long-wavelength light into more useful shorter wavelength light. Scientists from Tokyo Institute of Technology have revisited a materials approach previously deemed lackluster—using a molecule originally developed for organic LEDs—and have achieved outstanding performance and efficiency. Their findings pave the way for many novel photonic technologies, such as better solar cells and photocatalysts for hydrogen and hydrocarbon productions.

25. Newly improved quantum algorithm performs full configuration interaction calculations without controlled time evolutionsПт, 26 ноя[−]
Категория(?)  
In a continuing effort to improve upon previous work, a research team at the Graduate School of Science, Osaka City University, has applied its recently developed Bayesian phase difference estimation quantum algorithm to perform full configuration interaction (full-CI) calculations of atoms and molecules without simulating the time evolution of the wave function conditional on an ancillary qubit. Superior to conventional methods in terms of parallel execution of quantum gates during quantum computing, this new algorithm is expected to be much easier to implement in actual quantum computers.

28. Bolometers operate at higher temperatures using new superconducting materialПт, 26 ноя[−]
Категория(?)  
Receivers combining a superconducting hot electron bolometer (HEB) with a reference oscillator are the work horses of supra-terahertz astronomy, observing for example star formation and galaxy evolution. Until now, mainly niobium nitride HEBs—that have to be operated at low temperatures of 4 Kelvin—have been selected for space and balloon borne telescopes. A team of scientists at SRON, TU Delft, Chalmers University and RUG have now demonstrated a HEB based on magnesium diboride, a new superconducting material, which not only can simultaneously detect more spectral lines, but can also be operated around 20 Kelvin. The latter can significantly reduce the cost, weight, volume, and required electrical power of space instruments. The study is published in Applied Physics Letters.
