Nor confirm the accumulation of 2 GHZ statesN– photons. (b) Sketch of the experimental setup. A Ti:sapphire laser with a wavelength of 775 nm pumps a Bell-state bias source based on parametric downconversion in a Sagnac configuration (blue area). One photon from each emitted Bell pair is detected and triggers the feed-forward (red arrows), and …

The study shows that the gravitational forces deep in the Earth have a great impact on the evolution of the landscape

The study shows that the gravitational forces deep in the Earth have a great impact on the evolution of the landscape

These images from the modeling illustrate the development of the metamorphic core complex showing crustal stresses and rates of deformation, faulting, uplift of deeper rocks, and sedimentation from surface erosion. These core complex development processes occur after the topography supporting the thickened crustal root is weakened by the input of heat, fluids, and partial melting. …

“Something strange is happening” – Physicists answer a decades-old question

Physicists have answered a long-standing question regarding the interaction of quantum particles in a disordered system. Another kind of chaos Physicists from the University of California, Santa Barbara, the University of Maryland, and the University of Washington have solved a long-standing physics puzzle: How do interactions between particles affect dynamic localization? “It’s a really old …

Powerful physics tool could help scientists understand complex ecosystems | Science

Your gut is home to microbial madness. Hundreds of trillions of bacteria belonging to countless species interact with each other in complex ways that can keep you healthy and make you sick. Teasing out these interactions would seem like an impossible task. Now, microbiologists have found help from an unlikely source: physics. A new experiment …

The 80-year-old mystery in static electricity has finally been solved

The 80-year-old mystery in static electricity has finally been solved

Charge mosaic on contact charged dielectrics. (a) In a conventional view, two electrically neutral materials (gra) brought into contact and then uniformly charged (bottom left), one positive (red) and one negative (blue). In an alternative scenario (bottom right), each surface develops a highly uneven “charge mosaic” with neighboring domains of opposite charge polarities. (b) Loading …
