particle : any of the basic units of matter and energy (such as a molecule, atom, proton, electron, or photon) — Webster
Particle is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass. They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials. Particles can also be used to create scientific models of even larger objects depending on their density, such as humans moving in a crowd or celestial bodies in motion. — Wikipedia
Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter and radiation. Although the word particle can refer to various types of very small objects (e.g. protons, gas particles, or even household dust), particle physics usually investigates the irreducibly smallest detectable particles and the fundamental interactions necessary to explain their behavior. By our current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. — Wikipedia

Quantum computers could vastly increase the capabilities of IT systems, bringing major changes worldwide. However, there is still a long way to go before such a device can actually be constructed, because it has not yet been possible to transfer existing molecular concepts into technologies in a practical way. This has not kept researchers around the world away from developing and optimising new ideas for individual components. Chemists at Friedrich Schiller University in Jena (Germany) have […]

Plasmonic quantum size effects in silver...
on December 5, 2018 at 12:53 pm
When metallic dimensions are reduced to the nanoscale, a phenomenon termed localized surface-plasmon resonance (LSPR) appears due to electron oscillations, resulting in distinct optical properties suited for advanced imaging and sensing technologies. As particles approach the quantum regime with dimensions less than 10 nm in diameter, however, the existing knowledge of their properties becomes quite hazy. The plasmonic character depends on the collective electronic excitation that can be tuned […]

Bose-Einstein condensates cannot currently detect...

The gravitational waves created in the depths of space indeed reach Earth. Their effects, however, are so small that they could only be observed so far using kilometer-long measurement facilities. Physicists therefore discuss whether Bose-Einstein condensates with their ordered quantum properties could also detect these waves. Astronomers have now looked at these suggestions and have soberly determined that such evidence is far beyond the reach of current methods. […]

A new study represents a significant advance in topological transistors and beyond-CMOS electronics. First time that the topological state in a topological insulator has been switched on and off using an electric field. Researchers proved this is possible at room temperature, which is necessary for any viable replacement to CMOS technology in everyday applications. […]

A special laser system has been developed, using two slightly different frequency combs. This allows for chemical analysis on tiny spaces -- it is a millimeter-format chemistry lab. With this new patent-pending technology, frequency combs can be created on a single chip in a very simple and robust manner. […]
A new 'spin' on kagome lattices
on December 7, 2018 at 8:42 pm
The kagome ferromagnet Fe3Sn2 exhibits an electronic state that couples unusually strongly to an applied magnetic field that can be rotated to point in any direction of a 3-dimensional space, revealing that magnetization drives -- in quantum scale -- a 'giant' energy shift within the material, an international team of researchers has found.
