considering the group of Lorentz determines the elements that correspond to the representation

(i,j) - (1/2,1/2) , (1,0),(0,1)

find generators for this transformation and the properties which these elements to the group of rotation

anyone know how i find theses generators and these elements ?

Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
