New states of matter. Fake reality. Real silence.
Researchers have recently produced a "human scale" demonstration of a new phase of matter called quadrupole topological insulators (QTI) that was recently predicted using theoretical physics. These were the first experimental findings to validate this theory. The researchers reported their findings in the journal Nature. The team's work with QTIs was born out of the…

Quantum space. Ghostly differences. A calm lake.
The foundation stone of quantum mechanics doesn't just describe the behavior of infinitesimal subatomic particles – it also governs the movement of the largest and most massive objects in the Universe, says a prominent astrophysicist. Planetary scientist Konstantin Batygin was exploring the concept of astrophysical disks – sometimes called accretion disks; massive self-gravitating swirls of…

Eternal recurrence… Cycles… Dasein into nothingness…
It is one of the most astonishing results of physics: when a complex system is left alone, it will return to its initial state with almost perfect precision. Gas particles, for example, chaotically swirling around in a container, will return almost exactly to their starting positions after some time. This "Poincaré Recurrence Theorem" is the…

Endless days… Time… Infinity… Zero…
A Duke University researcher has a new explanation for why those endless days of childhood seemed to last so much longer than they do now - physics. According to Adrian Bejan, the J.A. Jones Professor of Mechanical Engineering at Duke, this apparent temporal discrepancy can be blamed on the ever-slowing speed at which images are…

Emulating… Existing…
For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials that were theorized to exist only in four-dimensional space. An international team of researchers from Penn State, ETH Zurich in Switzerland, the University of Pittsburgh, and the Holon Institute of Technology in Israel have…
