For following can I get explanation for the answers. (step by step solution would be nice). Prove, for any Hermitian operator , and any arbitrary state If>, that the quantity <fIÑ If> is real. The expectation value of any quantity represented by a Hermitian operator is always real. This is the reason for using Hermitian operators to represent measurable quantities. For each of the following matrices, state weather it is unitary and/or Hermitian. [1] « [1] -[9] «» (e :)...
Use the following information To help you solve the following questions. Show all work for thumbs up. 3.1 Rotations and Angular-Momentum Commutation Relations 159 We are particularly interested in an infinitesimal form of Ry: (3.1.4) where terms of order & and higher are ignored. Likewise, we have R0= ° :- R(E) = 1 (3.1.5) and (3.1.5b) - E01 which may be read from (3.1.4) by cyclic permutations of x, y, zthat is, x y , y → 2,2 → x....
