Quantum entanglement is something that links particles in such a way that they instantly respond to and affect each other, even over a large distance. The effect is such that it appears to defy the conventional laws of physics. Hence, Albert Einstein called it a “spooky action".

Astronomers know when they're seeing a gravitationally lensed object because of an effect called Einstein's Ring. This is a halo of light bent around the lensed object. The astronomers were already observing the lensing event with the Hubble Space Telescope to study to the supernova Refsdal, which was ...
LETTER: A little physics lesson on the effect of very high speeds on distance. In this March 6, 2017 file photo, Britain's late Professor Stephen Hawking delivers a keynote speech as he receives the Honorary Freedom of the City of London during a ceremony at the Guildhall in the City of London.
The universe is loaded with lots of strange symmetries between seemingly dissimilar systems, thanks to similar underlying physics. Take an electrical circuit, a spring, and a swinging pendulum. These simple oscillators might look completely different, but they are governed by the same mathematical ...

These new types of stars have been dubbed "semiclassical relativistic stars" because they the result of both classical and quantum physics. One of the differences would be that the star would be horizonless – like another theoretical star made possible by quantum physics, the gravastar. There wouldn't be ...
The general reasons for this “urban heat island” (UHI) effect are not hard to understand, but a statistical analysis now establishes a connection between the magnitude of the ... Pellenq and his colleagues adapted a tool commonly used in condensed matter physics called the radial distribution function.
While the same physics applies to the electron (which does not have a similar magnetic anomaly), Morishima and Futamase say that the effect does not lead to a boost in the measured magnetic moment of the electron. The three preprints have not yet been peer reviewed but have already caused a stir on ...
Scientists have uncovered some preliminary evidence for a nuclear physics effect first predicted back in the 1970s. The physics universe ...

High-energy beams of protons have a number of different of uses ranging from fundamental studies of particle physics to the destruction of tumours in cancer ... energy was being approached – and now they have discovered a previously unforeseen magnetization effect that may be putting on the brakes.
The findings provided a unified theoretical framework to understand a phenomenon known as 'linear unsaturating magnetoresistance', as well as clear predictions on how to manipulate the effect. Prior to their research, two separate theoretical mathematical models had been proposed to describe how the ...

You might know that particles have an innate property called spin (they're not really spinning, but follow mathematical rules that look pretty similar to the physics of spinning). RHIC can filter its proton beams so they only contain particles spinning in one direction. Back in the early 2000s, RHIC scientists sent ...

The solar cycle is driven by the solar dynamo, which is an interplay between magnetic fields, convection and rotation. However, our understanding of the physics underlying the solar dynamo is far from complete. One example is the so-called Maunder Minimum, a period in the 17th century, where spots ...
Thanks to some rather advanced calculations – which won the Nobel Prize for Physics in 2016 – we know that the quantum Hall effect points to the existence of a fourth spatial dimension. What these new experiments do is give us a picture of the effects that this fourth dimension might have. The European ...

Although with no real equivalent in classical physics, it can be used much like charge to store, manipulate and transport information. Graphene is ... The spin-orbit coupling (SOC) interaction offers just such a means, though in graphene, this must be 'borrowed' from other materials via the proximity effect.
The tiny effect is much like the effect a laser has on an atom in a device called optical tweezers, which are used to trap and study atoms, a discovery that led to the 1997 Nobel Prize in Physics shared by former UC Berkeley professor Steven Chu, now at Stanford, Claude Cohen-Tannoudji and William D.
