‘Quantum Atmospheres’ May Reveal Secrets of Matter
A new theory proposes that the quantum properties of an object extend into an “atmosphere” that surrounds the material.
The End of Theoretical Physics as We Know It
Computer simulations and custom-built quantum analogues are changing what it means to search for the laws of nature.
Closed Loophole Confirms the Unreality of the Quantum World
A quickly closed loophole has proved that the “great smoky dragon” of quantum mechanics may forever elude capture.
Real-Life Schrödinger’s Cats Probe the Boundary of the Quantum World
Recent experiments have put relatively large objects into quantum states, illuminating the processes by which the ordinary world emerges out of the quantum one.
Quantum Correlations Reverse Thermodynamic Arrow of Time
A recent experiment shows how quantum mechanics can make heat flow from a cold body to a hot one, an apparent (though not real) violation of the second law of thermodynamics.
Why Stephen Hawking’s Black Hole Puzzle Keeps Puzzling
The renowned British physicist, who died at 76, left behind a riddle that could eventually lead his successors to the theory of quantum gravity.
Physicists Find a Way to See the ‘Grin’ of Quantum Gravity
A recently proposed experiment would confirm that gravity is a quantum force.
Elusive Higgs-Like State Created in Exotic Materials
Two teams of physicists have created the "Higgs mode" – a link between particle physics and the physics of matter. The work could help researchers understand the strange behavior of deeply quantum systems.
Physicists Aim to Classify All Possible Phases of Matter
A complete classification could lead to a wealth of new materials and technologies. But some exotic phases continue to resist understanding.
