First a line of invisible words:

${\displaystyle \ }$

which is:

The following codes are funny,I collect it just for amusement:

How about math?

How can you put subscripts on all the four corners of a symbol?Just use a fake object to trick on,br${\displaystyle \sigma \_\sigma }$:

{}_1^2J_3^4

${\displaystyle {}_{1}^{2}J_{3}^{4}}$

Atomic state:

2\ {}^2S_{1/2}

${\displaystyle 2\ {}^{2}S_{1/2}}$

For the cumbersome:

{}_1^{1234}J_1^{1234}

${\displaystyle {}_{1}^{1234}J_{1}^{1234}}$

Solution:

{}_{\ \ \ \ 1}^{1234}J_1^{1234}

${\displaystyle {}_{\ \ \ \ 1}^{1234}J_{1}^{1234}}$

a useful TeXnicality

${\displaystyle Y\ {\stackrel {\mathrm {def} }{=}}\ 1(y^{*}>0)}$
