Key Equations

$$i\hbar\frac{d}{dt}|\psi_S(t)\rangle = H|\psi_S(t)\rangle$$
$$H = H_0 + H_{\text{int}}$$
$$\boxed{i\frac{d}{dt}|\psi_I(t)\rangle = H_{\text{int},I}(t)\,|\psi_I(t)\rangle}$$
$$|\psi_I(t)\rangle = U(t,t_0)\,|\psi_I(t_0)\rangle$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
