imatfaal Posted August 22, 2013 Share Posted August 22, 2013 How does one enter dirac bra kets in Latex? From the net it seemed I should use \ket{00} but this got me a syntax error. BTW - protip: unless you are alone and have some time to kill do not search on latex bra ket Link to comment Share on other sites More sharing options...
mississippichem Posted August 22, 2013 Share Posted August 22, 2013 (edited) I usually use | \psi \rangle to get [math] | \psi \rangle [/math]. Along similar lines you can use \langle \phi | \psi \rangle giving [math] \langle \phi | \psi \rangle [/math] when you need an inner product. It's cumbersome, but the words "rangle" and "langle" make me smile. Edited August 22, 2013 by mississippichem 3 Link to comment Share on other sites More sharing options...
