Functional Analysis for Quantum Mechanics
... Remark. At this point one should wonder why one uses normed spaces, but defines operators merely in algebraic terms. For linear maps between normed spaces the concept of continuity is well-defined. This point is rarely made in linear algebra courses, since A is assumed to be finite-dimensional and, ...

9. Time-dependent Perturbation Theory
... Of course, there is a companion process in which the electron undergoes a transition from state b to state a, giving up energy Eb − Ea = ~ω0 in the process. We can calculate the probability for this process by assuming that ca(0) = 0, cb(0) = 1, and following the above derivation, yielding exactly ...

Yangian Symmetry in Yang
... When an infinite number of operators mix even one loop anomalous dimensions can lead to sophisticated dynamical problems. If some kind of gauge-string duality holds we can translate the problem of solving the full Callan-Symanzik equation (`dilatation dynamics’) to a matrix model or a sigma model at ...
