A quantum phenomenon in a system of bosons consisting in the fact that, at a temperature below the so-called degeneracy temperature, part of the particles of the system accumulates in the state with zero momentum (if the…

Bose–Einstein distribution , a formula describing the distribution over energy levels of identical particles with zero or integer spin, on condition that the interaction of the particles in the system is weak and can be …

Bose–Einstein statistics , the quantum statistics applied to systems of particles with zero or integer spin (0, 1, 2... in units of ћ.).

Einstein , (E), a unit of energy sometimes used in photochemistry.

Einstein coefficients , characterise the probabilities of radiative quantum transitions.

Einstein-de Haas effect , when a body is magnetised along some axis it acquires, about that axis, an angular momentum proportional to the magnetisation it has gained.

Equivalence principle , the statement that a gravitational field in a small region of space and time (in which it can be taken as uniform and constant in time) is identical in its manifestations to an accelerated frame o…
