Physics news

A new theoretical model to capture spin dynamics in Rydberg molecules

Rydberg molecules are giant molecules made up of tens or hundreds of atoms bound to a Rydberg atom. These molecules have a permanent dipole (i.e., a pair of oppositely charged or magnetized poles), as one of their atoms is in a highly excited state.

Researchers generate terahertz laser with laughing gas

Within the electromagnetic middle ground between microwaves and visible light lies terahertz radiation, and the promise of "T-ray vision."

Research team develops tiny low-energy device to rapidly reroute light in computer chips

Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have developed an optical switch that routes light from one computer chip to another in just 20 billionths of a second—faster than any other similar device. The compact switch is the first to operate at voltages low enough to be integrated onto low-cost silicon chips and redirects light with very low signal loss.

Top cosmologist's lonely battle against 'Big Bang' theory

James Peebles won this year's Nobel prize in physics for helping transform the field of cosmology into a respected science, but if there's one term he hates to hear, it's "Big Bang Theory."

Quantum transition makes electrons behave as if they lack spin

The common phase transitions are those that occur as a function of temperature variation. Ice changes phase to become liquid water at 0 degrees Celsius. Liquid water changes phase to become water vapor at 100 degrees Celsius. Similarly, magnetic materials become nonmagnetic at critical temperatures. However, there are also phase transitions that do not depend on temperature. They occur in the vicinity of absolute zero [-273.15 degrees Celsius] and are associated with quantum fluctuations.

Physicists irreversibly split photons by freezing them in a Bose-Einstein condensate

Light can be directed in different directions, usually also back the same way. Physicists from the University of Bonn and the University of Cologne have, however, succeeded in creating a new one-way street for light. They cool photons down to a Bose-Einstein condensate, which causes the light to collect in optical "valleys" from which it can no longer return. The findings from basic research could also be of interest for the quantum communication of the future. The results are published in Science.

Quantum physics: Our study suggests objective reality doesn't exist

Alternative facts are spreading like a virus across society. Now it seems they have even infected science—at least the quantum realm. This may seem counter intuitive. The scientific method is after all founded on the reliable notions of observation, measurement and repeatability. A fact, as established by a measurement, should be objective, such that all observers can agree with it.

From a cloud of cold and a spark, researchers create and stabilize pure polymeric nitrogen for the first time

Scientists have long theorized that the energy stored in the atomic bonds of nitrogen could one day be a source of clean energy. But coaxing the nitrogen atoms into linking up has been a daunting task. Researchers at Drexel University's C&J Nyheim Plasma Institute have finally proven that it's experimentally possible—with some encouragement from a liquid plasma spark.

New solar power generator to be deployed to space station

How do you make the world's most powerful neutrino beam?

What do you need to make the most intense beam of neutrinos in the world? Just a few magnets and some pencil lead. But not your usual household stuff. After all, this is the world's most intense high-energy neutrino beam, so we're talking about jumbo-sized parts: magnets the size of park benches and ultrapure rods of graphite as tall as Danny DeVito.

Astronomy & Space news

IPTF14hls may be a variable hyper-wind from a very massive star, study suggests

A source known as iPTF14hls, assumed to be a Type IIP supernova, may be a long-term outflow similar to stellar winds, according to a new study published November 5 on The new research proposes that iPTF14hls is most likely a so-called "hyper-wind"—an extreme mass outflow from a massive star.

China tests Mars lander in international cooperation push

China showed off its Mars spacecraft during a landing test Thursday as the country pushes for inclusion in more global space projects.

Two cosmic peacocks show violent history of the magellanic clouds

Two peacock-shaped gaseous clouds were revealed in the Large Magellanic Cloud (LMC) by observations with the Atacama Large Millimeter/submillimeter Array (ALMA). A team of astronomers found several massive baby stars in the complex filamentary clouds, which agrees well with computer simulations of giant collisions of gaseous clouds. The researchers interpret this to mean that the filaments and young stars are telltale evidence of violent interactions between the LMC and the Small Magellanic Cloud (SMC) 200 million years ago.

What's the best way to sail from world to world? Electric sails or solar sails?

In the past decade, thousands of planets have been discovered beyond our solar system. This has had the effect of renewing interest in space exploration, which includes the possibility of sending spacecraft to explore exoplanets. Given the challenges involved, a number of advanced concepts are currently being explored, like the time-honored concept of a light sail (as exemplified by Breakthrough Starshot and similar proposals).
