The coldest spot in the known universe

Everyone knows that space is cold. In the vast gulf between stars and galaxies, the temperature of gaseous matter routinely drops to 3 Kelvin, or 454 degrees below zero Fahrenheit.

It's a negative on negative absolute temperatures

The concept of a perpetual motion machine is an enticing one: Imagine a machine that runs continuously without requiring any external energy—a feat that could make refueling vehicles a thing of the past.

Man-made material shows surprisingly magnetic personality

(Phys.org) —Scientists from SLAC and Stanford have used finely tuned X-rays at the Stanford Synchrotron Radiation Lightsource (SSRL) to pin down the source of a mysterious magnetism that appears when two materials are sandwiched ...

Synchrotrons help bring superconductors out of the cold

(Phys.org) -- The longstanding search for a room temperature superconductor is fueled by a tantalizing set of possible applications that sound like science fiction: infinitely long power lines that never lose energy, magnetically ...

Quantum storage system with long-term memory

(Phys.org) -- Credit cards which are completely fraud-proof and passports which cannot be forged: quantum physics could make both of these possible. This is explained by the fact that the quantum mechanical state of a particle, ...

A microscopic view on quantum fluctuations

(PhysOrg.com) -- Scientists at the Max Planck Institute of Quantum Optics achieve direct imaging of quantum fluctuations at absolute zero temperature.

Supersolid helium unlikely

(PhysOrg.com) -- Does helium-4 become a "supersolid" near absolute zero? What previous researchers thought might be a supersolid transition is better explained by changes in the solid's resistance to shearing, according to ...
