according to

texdoc physics


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

I have the following tex code,

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


which provides the following equation 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!
