The Planck constant, or Planck's constant, denoted by h {\textstyle h} , is a fundamental physical constant of foundational importance in quantum mechanics:...

An electron microscope is a microscope that uses a beam of electrons as a source of illumination. They use electron optics that are analogous to the glass...

In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when...

Quantum dots (QDs) or semiconductor nanocrystals are semiconductor particles a few nanometres in size with optical and electronic properties that differ...

In theoretical physics, quantum nonlocality refers to the phenomenon by which the measurement statistics of a multipartite quantum system do not allow...

In geometry and physics, spinors (/spɪnər/) are elements of a complex number-based vector space that can be associated with Euclidean space. A spinor transforms...

The Fresnel equations (or Fresnel coefficients) describe the reflection and transmission of light (or electromagnetic radiation in general) when incident...

In audio engineering, electronics, physics, and many other fields, the color of noise or noise spectrum refers to the power spectrum of a noise signal...

In physics, the principle of locality states that an object is influenced directly only by its immediate surroundings. A theory that includes the principle...

In statistical mechanics, the virial theorem provides a general equation that relates the average over time of the total kinetic energy of a stable system...

The Wheeler–Feynman absorber theory (also called the Wheeler–Feynman time-symmetric theory), named after its originators, the physicists, Richard Feynman...

The Koopman–von Neumann (KvN) theory is a description of classical mechanics as an operatorial theory similar to quantum mechanics, based on a Hilbert...

In physics, a time projection chamber (TPC) is a type of particle detector that uses a combination of electric fields and magnetic fields together with...

The path of least resistance is the physical or metaphorical pathway that provides the least resistance to forward motion by a given object or entity,...

Basil J. Hiley (born 1935), is a British quantum physicist and professor emeritus of the University of London. Long-time colleague of David Bohm, Hiley...

In classical mechanics, Poinsot's construction (after Louis Poinsot) is a geometrical method for visualizing the torque-free motion of a rotating rigid...

A Faraday balance is a device used to measure magnetic susceptibility, a property of matter is related to the force experienced by a substance in a magnetic...

A cryogenic processor is a device engineered to reduce the temperature of an object to cryogenic levels, typically around −300°F (−184.44°C), at a moderate...
