    You can also use \mathds{1} from \usepackage{dsfont}, which looks similar but is not pixelated.

  • For a bold (as opposed to double-stroke) zero 0 you can use $\boldsymbol{0}$ from \usepackage{amsmath} or $\bm{0}$ from \usepackage{bm}.

  • @Schrödinger'scat sorry I meant double stroke 0 \mathds{0} is just nothing
