an ensemble of techniques which serves to treat the infinities which appear in quantum field theory or statistical mechanics.

the phenomenon of two particles depending on each other, once they have interacted, even after becoming physically separated.

Negatively charged particle with spin 1/2. A component of mundane terrestrial matter, and part of all neutral atoms and molecules. It has a mass about 1/1800 that of a proton. Its antiparticle is the…

Partial differential equation which describes the time evolution of the wavefunction of a quantum system. It is one of the first and most fundamental equations of quantum mechanics.
 × 157
just because your question involves math! If your question is on simplification of a mathematical expression, please ask it at math.stackexchange.com The mathematics tag covers non…
 × 155
The study of how the properties of matter arise from its structure at all scales and of how processing can be used to modify those properties (often in pursuit of a specific application).

The union of special (SR) and general (GR) relativity. Use this tag if both SR and GR apply.
× 136
A particle that emerges from the theoretical mechanism that is thought to give other particles mass.
 × 132
The historical development of physics concepts: who did what and when.
 × 132
a process in which energetic particles or energetic waves travel through a medium or space. The particles or waves radiate (i.e., travel outward in all directions) from a source.
 × 132
for Heisenberg quantum mechanical uncertainty principle.
× 131 × 130
According to the current cosmological theories, it's the model that explains the early life of the universe, starting from a rapid expansion of hot and dense matter.
 × 127
used to describe any system with a "linear" restoring force that tends to return the system to a equilibrium state. There is both a classical harmonic oscillator and …

× 124
a general term for several physical processes in which radiation of some sort changes direction due to an interaction with a particle. Scattering can be classified by the type of radiati…

an almost perfectly symmetric yellow dwarf star [spectral class G2V] which is at the center of our Solar System.
 × 120
standards of measurement used for different types of quantities.
× 120 × 118
A nucleus made of protons and neutrons surrounded by a cloud of electrons equal in number to the protons.
 × 118
questions concerning measurements, experiments, and activities that demonstrate physics and are safe to do at home, require at most one tool or ingredient not readily available, and can be interpreted…
 × 116
Study of macroscopic and microscopic phenomena in chemical systems in terms of physical laws and concepts [thermodynamics, statistical mechanics, kinetic theory, quantum mechanics...].
× 115
A subset of [tag:fluid-dynamics] concerning primarily forces such as lift and drag generated on bodies as they move through gasses or as gasses move through the body (typically air).
× 115
Geometric object with magnitude (length) and direction.
 × 114
Questions concerning computations performed on a quantum-computer. DO NOT USE THIS TAG just because the question concerns a computation of a quantum-system!
