You can print the h-bar or Reduced Plank constant by default \hbar command in the latex document.
Symbol | H-bar |
---|---|
Type of symbol | Mathematics |
Package (requirement) | No |
Argument | No |
Latex command | \hbar |
Example | \hbar → ℏ |
\documentclass{article}
\begin{document}
$$ E = \hbar \omega $$
$$ \hbar = \frac{h}{2\pi} $$
$$ p = \hbar K $$
\end{document}
Output :
And different packages have the same command, which returns the same output. Examples are amsmath, fdsymbol, and boisik.
There is another type of h-bar symbol in latex that has structural light differences. For this, take help of boisik package.
\documentclass{article}
\usepackage{boisik}
\begin{document}
$$ J^2 = j(j+1)^2 \hslash $$
$$ J_z = m \hslash $$
$$ \Delta x . \Delta p \geq \frac{\hslash}{2}$$
\end{document}
Output :
Use another package for h-bar symbol in LaTeX like tipa, wsuipa, phonetic, etc.
The following program uses four different packages and different commands to define the same h-bar symbol.
Command (package) | Symbol |
---|---|
\textcrh (tipa) |
ℏ |
\crossh (wsuipa) |
ℏ |
\plank (phonetic) |
ℏ |
\textcrh (t4phonet) |
ℏ |
\documentclass{article}
\usepackage{tipa, phonetic, wsuipa}
\begin{document}
$ p^u = \textcrh K^u $\\[6pt]
$ p^N $ = \planck $\left(\frac{w}{c}, \vec{K} \right) $\\[6pt]
\crossh = 1.056 $ \times 10^{-34} J.S $
\end{document}
Output :
