Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without requiring a new chip for new colors. This form of nonlinear photonics could ...

Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark photons to be considered serious candidates for dark matter, with promising ...

ABSTRACT: The appearance of a particle in a certain point in space, the full waves and the empty waves are considered as a consequence of subquantum processes. The experiment is described that ...

Supersolids are a unique phase of matter that combine the friction-free flow of superfluids with an ordered structure. They have previously been achieved only with condensates of ultracold atoms. The ...

ABSTRACT: We present a new perspective on the P vs NP problem by demonstrating that its answer is inherently observer-dependent in curved spacetime, revealing an oversight in the classical formulation ...

Lighten up, people: a fascinating new paper has dropped that describes the shape of a single photon, the smallest possible form of energy in an electromagnetic field that we commonly know as light.

Quantum physicists are familiar with wonky, seemingly nonsensical phenomena: atoms and molecules sometimes act as particles, sometimes as waves; particles can be connected to one another by a “spooky ...

Prototype quantum photonic-dimer laser uses entanglement to bind photons and deliver a powerful beam of concentrated light that can shine through adverse weather like thick fog. When you purchase ...

West Lafayette, Ind. (WLFI) - Renowned scientist Alain Aspect was invited to speak at Purdue on Monday about his work on quantum physics, which sparked a second quantum revolution. The lecture, titled ...

WEST LAFAYETTE, Ind.—Renowned French scientist Alain Aspect, who won the 2022 Nobel Prize for his pathfinding research in quantum physics, will give a lecture on Monday (May 13) at Purdue University ...
