Quantum vacuum may allow stars to exist in unconventional configurations

Mar 12, 2018 (SPX)

"As a consequence of the attractive and repulsive forces at play, a massive star can either become a neutron star, or turn into a black hole" says Carballo-Rubi...

Physicists lay groundwork to better understand the birth of the universe

Mar 07, 2018 (SPX)

To date, theoretical physicists have developed theories that explain how parts of the universe work: classical mechanics for objects at everyday sizes and speed...

The Schrodinger Equation makes an unlikely appearance at the astronomical scale

Mar 07, 2018 (SPX)

JILA team invents new way to 'see' the quantum world

Mar 06, 2018 (SPX)

The technique combines spectroscopy, which extracts information from interactions between light and matter, with high-resolution microscopy. As described in Phy...

Roton quasiparticles observed in quantum gas

Mar 06, 2018 (SPX)

The behavior of such a special fluid is mainly dictated by two types of excitations at low temperature, as their moderate energy cost allows to easily excite th...

Exotic state of matter: An atom full of atoms

Mar 06, 2018 (SPX)

A team of researchers has now presented this state of matter in the journal Physical Review Letters. The theoretical work was done at TU Wien (Vienna) and Harva...

More efficient simulators by storing time in a quantum superposition

Mar 06, 2018 (SPX)

The suggestion comes from researchers Mile Gu and Thomas Elliott in Singapore, who describe their proposal in a paper published 1 March in npj Quantum Informati...

Dressing atoms in an ultracold soup

Mar 06, 2018 (SPX)

"I am amazed that we've discovered a new way that atoms assemble," said Rice University physicist Tom Killian. "It shows how rich the laws of physics and chemis...

Artificial intelligence techniques reconstruct mysteries of quantum systems

Mar 06, 2018 (SPX)

For the first time, physicists have demonstrated that machine learning can reconstruct a quantum system based on relatively few experimental measurements. This ...

Scientists observe a new quantum particle with properties of ball lightning

Mar 06, 2018 (SPX)

In an extremely sparse and cold quantum gas, the physicists have created knots made of the magnetic moments, or spins, of the constituent atoms. The knots exhib...

Three-dimensional skyrmion: Scientists observe theoretical particle for first time

Mar 02, 2018 (UPI)

The particle, observed cold quantum gas, isn't a normal particle composed of electrons, protons and electrons. It is a quantum particle, the energy signature cr...

Can strongly lensed type 1a supernovae resolve cosmology's biggest controversy

Mar 02, 2018 (SPX)

This discovery provided the first evidence of what is now the reigning model of the universe: "Lambda-CDM," which says that the cosmos is approximately 70 perce...

Unlocking the secrets of the universe

Mar 01, 2018 (SPX)

Then, for the next 50-100 million years, gravity slowly pulled the densest regions of gas together until ultimately the gas collapsed in some places to form the...

Astronomers detect earliest evidence yet of hydrogen in the universe

Mar 01, 2018 (SPX)

The scientists have traced the signals to just 180 million years after the Big Bang, making the detection the earliest evidence of hydrogen yet observed. They a...

Quantum recurrence: Everything goes back to the way it was

Feb 27, 2018 (SPX)

This "Poincare Recurrence Theorem" is the foundation of modern chaos theory. For decades, scientists have investigated how this theorem can be applied to the wo...

A quadrillionth of a second in slow motion

Feb 27, 2018 (SPX)

An important intermediary step in many chemical processes is ionization. A typical example of this is photosynthesis. The reactions take only a few femtoseconds...

Scientists discover atoms inside the orbiting electrons of a 'giant atom'

Feb 26, 2018 (UPI)

The atoms within the "giant atom" form weak bonds, producing a new exotic state of matter -- what scientists have dubbed "Rydberg polarons." The discovery combi...

Some black holes erase your past

Feb 22, 2018 (SPX)
