The standard model of particle physics only accounts for 20% of matter in the universe. Physicists have theorized that the remaining 80% is made up by so-called dark matter, which consists of particles that do not emit, absorb ...
Quantum entanglement is the basic phenomenon underlying the functioning of a variety of quantum systems, including quantum communication, quantum sensing and quantum computing tools. This phenomenon results from an interaction ...
Researchers at the University of Colorado have recently developed a new technique to measure mechanical motion using simultaneous electromechanical amplification and cooling processes. Their method, presented in a paper published ...
The Deep Underground Neutrino Experiment (DUNE) is an international research collaboration aimed at exploring topics related to neutrinos and proton decay, which should start collecting data around 2025. In a recent study ...
Our current understanding of physics suggests that there are two main types of matter in the universe known as dark and baryonic matter. Dark matter is made up of material that scientists cannot directly observe, as it does ...
A quasiparticle is a disturbance or excitation (e.g. spin waves, bubbles, etc.) that behaves as a particle and could therefore be regarded as one. Long-range interactions between quasiparticles can give rise to a 'drag,' ...
Currently, atomic force microscopes (AFMs) are one of the most widely used tools for imaging, measuring, and manipulating matter at the nanoscale. One of the key components of an AFM is a microscale oscillator, which scans ...
(Phys.org)—Using data from the first-ever gravitational waves detected last year, along with a theoretical analysis, physicists have shown that gravitational waves may oscillate between two different forms called "g" and ...
Two scientists won the Nobel Prize in physics Tuesday for key discoveries about a cosmic particle that whizzes through space at nearly the speed of light, passing easily through Earth and even your body.

(Phys.org) —Is it possible that a moving object could have zero energy? The common sense answer is no, since motion itself is kinetic energy, but this answer has been challenged recently by the concept of quantum time crystals. ...
Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes is used to be synonymous with "oscillation". Oscillations occur not only in physical systems but also in biological systems and in human society.
