Increase in bracket sizes due to power symbol

1,009

according to

texdoc physics

you can use \ket* to suppress automatic sizing (see page 6)

    I have the following tex code,

    \begin{equation}
    \ket{f_{\alpha}(\bm{r}+\bm{e}_{\alpha} \Delta t, t+\Delta t)} = 
    \ket{f_{\alpha}(\bm{r},t)} -\bm{M}^{-1}\hat{\bm{S}}
    (\ket{m_{\alpha}(\bm{r},t)}-\ket{m_{\alpha}^{(eq)}(\bm{r},t)}),
    \end{equation}
    

    which provides the following equation eqn The right-most ket operator is bigger due to the ^(eq). How to bring the ket brace to normal size?

      Can you add the definition of \ket

      It's part of the physics package. You can refer this answer: tex.stackexchange.com/a/214731/44940

      in this answer (actually, a non-answer), Braket size problem, one of the examples uses \smash to diminish the height of what's inside the brakets. that's the approach i'd suggest. if you find that useful, i'll produce a "tailored" solution for this particular example.

      @DavidCarlisle -- thanks for mentioning the physics package. i only knew about braket, and the features and support are different. so what is done depends on which package is actually used.

      @DavidCarlisle: Works perfectly. Post this as answer!

      Just add the braket package after loading physics.
