Researchers Determine the Delay with Which Electrons in Atoms Respond to the Electromagnetic Forces of Light

Researchers from the Laboratory for Attosecond Physics generated for the first time visible flashes of light in attosecond dimensions. They dispatched the light-flashes to electrons in krypton atoms. Through the experiment the researchers have been able to display that the electrons, which are stimulated by the flashes, needed roughly 100 attoseconds to respond to the […]

Scientists Propose a New Method to Probe the Beginning of the Universe

New research from the Harvard-Smithsonian Center for Astrophysics suggests that oscillating heavy particles generated “clocks” in the primordial universe that could be used to determine what produced the initial conditions that gave rise to the universe. How did the universe begin? And what came before the Big Bang? Cosmologists have asked these questions ever since […]

Quantum Entanglement Achieved at Room Temperature

A newly published study from the University of Chicago and Argonne National Laboratory demonstrates how macroscopic entanglement can be generated at room temperature and in a small magnetic field. Entanglement is one of the strangest phenomena predicted by quantum mechanics, the theory that underlies most of modern physics: It says that two particles can be […]

Researchers Significantly Boost the Energy That Can Be Harnessed from Sunlight

A newly published study details how a quantum process increases the number of electrons produced when light strikes a metal-dielectric interface. Researchers believe this finding could lead to better solar cells or light detectors. The new approach is based on the discovery that unexpected quantum effects increase the number of charge carriers, known as electrons […]

Glueball a Particle Purely Made of Nuclear Force

Scientists from Vienna University believe they may have discovered the long-sought-after glueball, a particle composed of pure force. For decades, scientists have been looking for so-called “glueballs”. Now it seems they have been found at last. A glueball is an exotic particle, made up entirely of gluons – the “sticky” particles that keep nuclear particles […]

Scientists Create a Magnetic Wormhole

Physicists have created the first experimental wormhole that can connect two regions of space magnetically. It consists of a tunnel that transfers the magnetic field from one point to the other while keeping it undetectable – invisible – all the way. “Wormholes” are cosmic tunnels that can connect two distant regions of the universe, and […]
