bra-ket notation notation, is used to denote quantum states. How to write bra-ket/braket notation in Latex with braket package: braket , bra and ket.
To write to write bra-ket/braket notation or symbol, we must use bracket package:
\documentclass[12pt]{article}
\usepackage{braket}
\begin{document}
$$\braket{\alpha|\beta}$$
$$\braket{\alpha||\beta}$$
$$\braket{\alpha|T|\beta}$$
\end{document}
which gives:
$$\braket{\alpha|\beta}$$
$$\braket{\alpha||\beta}$$
$$\braket{\alpha|T|\beta}$$
To write to write bra notation or symbol, we must use bracket package:
\documentclass[12pt]{article}
\usepackage{braket}
\begin{document}
$$\bra{\alpha}$$
$$\bra \psi{(t)}$$
$$\bra {\gamma{(t)}}$$
\end{document}
which gives:
$$\bra{\alpha}$$
$$\bra \psi{(t)}$$
$$\bra {\gamma{(t)}}$$
To write to write ket notation or symbol, we must use bracket package:
\documentclass[12pt]{article}
\usepackage{braket}
\begin{document}
$$\ket{\Psi}$$
$$\ket \psi{(t)}$$
$$\ket {\gamma{(t)}}$$
\end{document}
which gives:
$$\ket{\Psi}$$
$$\ket \psi{(t)}$$
$$\ket {\gamma{(t)}}$$
\documentclass[12pt]{article}
\usepackage{braket}
\begin{document}
Schrodinger's equation governs the time evolution of quantum states. It says that the time dependence of a state $\ket{\psi}$ is given by
$$ \hat H \ket{\psi} = i\hbar \frac{\partial{}}{\partial t} \ket{\psi} $$
where $\hat H$ is the Hamiltonian of the system.
