The electron, on the other hand, is thought to be stable on theoretical grounds: the electron is the least massive particle with non-zero electric charge, so its decay would violate charge conservation. [97] The experimental lower bound for the electron's mean lifetime is 6.6 × 10 28 years, at a 90% confidence level. [9] [98] [99]
The electron quasiparticle has the same charge and spin as a "normal" (elementary particle) electron, and like a normal electron, it is a fermion. However, its mass can differ substantially from that of a normal electron; see the article effective mass. [1] Its electric field is also modified, as a result of electric field screening.
The quantum mind or quantum consciousness is a group of hypotheses proposing that local physical laws and interactions from classical mechanics or connections between neurons alone cannot explain consciousness, [1] positing instead that quantum-mechanical phenomena, such as entanglement and superposition that cause nonlocalized quantum effects, interacting in smaller features of the brain than ...
A quasiparticle produced as a result of electron spin–charge separation that can form both quantum spin liquid and strongly correlated quantum spin liquid: TI-polaron: Translational invariant polaron polaron Trion: A coherent excitation of three quasiparticles (two holes and one electron or two electrons and one hole) electron, hole Triplon
The W bosons are known for their mediation in nuclear decay: The W − converts a neutron into a proton then decays into an electron and electron-antineutrino pair. The Z 0 does not convert particle flavor or charges, but rather changes momentum; it is the only mechanism for elastically scattering neutrinos. The weak gauge bosons were ...
It links the classical electrostatic self-interaction energy of a homogeneous charge distribution to the electron's relativistic mass-energy. According to modern understanding, the electron is a point particle with a point charge and no spatial extent. Nevertheless, it is useful to define a length that characterizes electron interactions in ...
The starting point for McFadden and Pockett's theory is the fact that every time a neuron fires to generate an action potential, and a postsynaptic potential in the next neuron down the line, it also generates a disturbance in the surrounding electromagnetic field.
The more general description of matter waves corresponding to a single particle type (e.g. a single electron or neutron only) would have a form similar to = (,) (() /) where now there is an additional spatial term (,) in the front, and the energy has been written more generally as a function of the wave vector. The various terms given ...
