ℏ

\hslash

The symbol \hslash is used to represent the reduced Planck's constant, which is a fundamental constant in quantum mechanics. It is defined as Planck's constant divided by 2π and is often used in equations involving quantum mechanics and wave functions.

Examples

E = ℏ ω

Energy of a photon in terms of angular frequency \omega.

E = \hslash \omega

ℏ = \frac{h}{2 π}

Definition of the reduced Planck's constant in terms of Planck's constant h.

\hslash = \frac{h}{2\pi}

Ψ (x, t) = ψ (x) e^{- i \frac{E}{ℏ} t}

Wave function in quantum mechanics using the reduced Planck's constant.

\Psi(x, t) = \psi(x) e^{-i\frac{E}{\hslash}t}
