SU(2) representation: Irreps labeled by spin j (dimension 2j+1). Basis |j,m>, m = −j,...,+j. Ladder operators J± = Jx ± iJy with J±|j,m> = sqrt((j∓m)(j±m+1)) |j,m±1>.
While there are many textbooks on the subject—ranging from the purely mathematical (Hamermesh) to the application-heavy (Greiner)—one name consistently comes up in conversations among particle physicists: . Wu-ki Tung Group Theory In Physics Pdf
: Use your university library’s interlibrary loan or purchase the eBook. If cost is prohibitive, look for used paperback copies (often $30–50 on AbeBooks or eBay). Many students split the cost of an eBook and share a legal account. SU(2) representation: Irreps labeled by spin j (dimension
Among the pantheon of textbooks on this subject, one volume occupies a unique space—revered for its clarity, rigor, and direct applicability to quantum mechanics and particle physics. That book is . While there are many textbooks on the subject—ranging
