Polaritons can Simulate Artificial Molecules with Various Properties

Researchers from Skoltech and the University of Cambridge have shown that polaritons, the quirky particles that may end up running the quantum supercomputers of the future, can form structures behaving like molecules - and these "artificial molecules" can potentially be engineered on demand. The paper outlining these results was published in the journal Physical Review B Letters.

Harnessing Light Energy to Power Production of Chemicals from CO2

Carbon dioxide (CO2) in the atmosphere is a major factor that drives global warming. However, this gas could also be a useful resource.

IQuAn – Combining High Performance Computing and Quantum Computing

Partners from academia and industry, led by the University of Mainz, have started a collaborative research project with the ambitious goal to build a quantum computer, interface it with an existing supercomputer and also enable access to external users. Providing access to external parties is an important goal and a major step in bringing quantum computers out of the laboratory. This will stimulate applications and support the industry in finding solutions to certain complex problems, where quantum computers have a clear edge over classical computers.

New Method to Determine Surface Temperatures of Red Supergiants

The lives of red supergiants, a class of star, end as supernova explosions. To date, there are no clear insights into their lifecycles, partially because of the difficulties in quantifying their temperatures.

Physicists Discover the Hall Effect in a Nonmagnetic Quantum Material

In a twist befitting the strange nature of quantum mechanics, physicists have discovered the Hall effect -- a characteristic change in the way electricity is conducted in the presence of a magnetic field -- in a nonmagnetic quantum material to which no magnetic field was applied.

Meteorites Shed Light on Cosmic Origin of Heaviest Elements on the Periodic Table

A team of international researchers went back to the formation of the solar system 4.6 billion years ago to gain new insights into the cosmic origin of the heaviest elements on the periodic table.

Study Assesses the Dynamics of Positron Acoustic Waves in Dense Plasmas

The investigation of Electron-Positron-Ion (EPI) plasma----a fully ionised gas of electrons and positrons that includes astrophysical plasmas like solar winds----has attracted a great deal of attention over the last twenty years. A new study published in EPJ D by Garston Tiofack, Faculty of Sciences, University of Marousa, Cameroon, and colleagues, assesses the dynamics of positron acoustic waves (PAWS) in EPI plasmas whilst under the influence of magnetic fields, or magnetoplasmas.

Investigating the Roles of Cooperative Effects and Disorder in Photon Escape Rates from Atomic Gases

Whilst a great deal of research has studied the rates of photons escaping from cold atomic gases, these studies have used a scalar description of light leaving some of its properties untested.

Study Reveals the Largest Galaxy Cluster Formed in the Early Universe

A new study headed by scientists from the Instituto de Astrofísica de Canarias (IAC) and performed with OSIRIS—an instrument on the Gran Telescopio Canarias (GTC) —has identified the formation of the most thickly populated cluster of galaxies in the primitive universe.

Comet-Like Object Spotted Near Trojan Asteroid Population for the First Time

After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter. This is the first time a comet-like object has been spotted near the Trojan population.

Study Sheds New Light on Role of Angular Momentum in Nuclear Fission

A set of experiments performed at the ALTO particle accelerator facility based in Orsay, France, has demonstrated that the fragments ensuing from nuclear fission achieve their inherent angular momentum (or spin) only after the fission reactions and not before them, as is generally believed.

New Evidence of Cold Gas Pipelines Feeding Early, Massive Galaxies Found

To come into being, galaxies need a steady diet of cold gases to undergo gravitational collapse. The larger the galaxy, the more cold gas it needs to coalesce and to grow.

Study Proposes a Mechanism for Formation of Supermassive Black Holes from Dark Matter

A new theoretical study has proposed a novel mechanism for the creation of supermassive black holes from dark matter. The international team find that rather than the conventional formation scenarios involving 'normal' matter, supermassive black holes could instead form directly from dark matter in high density regions in the centres of galaxies.

QUASAR Project Aims to Lay the Foundations for Industrial Production of Quantum Processors

The quantum computer race is in full swing. Germany has long been one of the world leaders in basic research. An alliance between Forschungszentrum Jülich and the semiconductor manufacturer Infinion, together with institutes of the Fraunhofer-Gesellschaft (IAF, IPMS) as well as the Leibniz Association (IHP, IKZ), the universities of Regensburg and Konstanz and the quantum start-up HQS, now aims to apply the results to industrial production.

A New Method to Produce Beams of Entangled Atoms

Heads or tails- If we toss two coins into the air, the result of one coin toss has nothing to do with the result of the other. Coins are independent objects. In the world of quantum physics, things are different: quantum particles can be entangled, in which case they can no longer be regarded as independent individual objects, they can only be described as one joint system.
