Traffic jams lend insight into emperor penguin huddle
Emperor penguins maintain the tight huddle that protects them from the harsh conditions of an Antarctic winter with stop-and-go movements like cars in a traffic jam, a new study has shown.
Laser beam orientation controls light's quantum properties
Quickly switching the orientation of a laser beam enables control over the quantum properties of light.
Physicists find a way to study coldest objects in the universe
They are the coldest objects in the Universe and are so fragile that even a single photon can heat and destroy them.
A Whirling Dervish puts physicists in a spin
A force that intricately links the rotation of the Earth with the direction of weather patterns in the atmosphere has been shown to play a crucial role in the creation of the hypnotic patterns created by ...
Physicists add 'quantum Cheshire Cats' to list of quantum paradoxes
Classical physics shown to be equal to quantum theory when it comes to unusual experiments with light beams
Quantum mechanics provides such a different description of the world compared to classical physics that even Albert Einstein had problems comprehending the implications of the theory. However, sometimes the ...
Scientists propose quantum wells as high-power, easy-to-make energy harvesters
Water impurities key to an icicle's ripples
A group of physicists from Canada have been growing their own icicles in a lab in the hope of solving a mystery that has, up until now, continued to puzzle scientists.
New method speeds up stabilisation of chaotic systems
(Phys.org) —When chaos threatens, speed is essential; for example, when a pacemaker needs to stabilise an irregular heartbeat or a robot has to react to the information received from its environment. Both ...
Simulation sets atoms shivering
(Phys.org) —In "Harry Potter and the Sorcerer's Stone" (JK Rowling, 1997), Harry, Ron, and Hermione encounter a massive stone chessboard, one of many obstacles in their path. To advance, they must play, ...
New scheme for quantum computing
(Phys.org) —Tom Wong, a graduate student in physics and David Meyer, professor of mathematics at the University of California, San Diego, have proposed a new algorithm for quantum computing, that will speed ...
Physicists show self-correcting quantum computers are theoretically possible
Hair sensor uncovers hidden signals
An "artificial cricket hair" used as a sensitive flow sensor has difficulty detecting weak, low-frequency signals – they tend to be drowned out by noise. But now, a bit of clever tinkering with the flexibility ...
Gravity's lingua franca: Unifying general relativity and quantum theory through spectra; geometry
'Spooky action at a distance' aboard the ISS
(Phys.org) —Albert Einstein famously described quantum entanglement as "spooky action at distance"; however, up until now experiments that examine this peculiar aspect of physics have been limited to relatively ...
