26 Jun 2024: function with itself is positive definite. In fact, our normalisability requirement (3.1). ... The requirement that the wavefunctions are single valued functions then tells us that.

2 Jul 2024: AB. We will not impose any such requirements if [A, B] 6= 0. ... In this case, the requirements of the Kocken-Specker theorem tell us that one of these.

12 Jun 2024: Why don’t. we just do something much simpler and multiply entries together component by compo-. ... is because it’s only there that the ijk symbol has three entries.

31 May 2024: This conceptleads us to our final requirement: we require that, given any two distinct points, there. ... To do this, simply replace one of T. p(M) entries with a basis vector.

18 Jul 2024: The requirement that its determinant is 1 reduces this to 3 complex parameters, or 6. ... we’re missing something. What we’re missing is the additional requirement that the.

2 Jul 2024: This is a strong requirement. First, it relates the absorption and stimulated emission coecients. ... g1B12 = g2B21 (4.29). We see that, as promised, it is a thermodynamic requirement that stimulated emission.

18 Jul 2024: For now, we can. just do some simple counting. A general complex 2 2 matrix has 4 complex entries.The requirement that its determinant is 1 reduces this to 3 complex

26 Jun 2024: requirement that the wavefunction should be periodic, so that. ψ(x 2πR) = ψ(x). ... Not all solutions (2.5) obey this requirement. We must have. eik(x2πR) = eikx e2πikR = 1.

2 Jul 2024: ΘeiHt/ |ψ(0)⟩ = eiHt/ Θ |ψ(0)⟩. Expanding this out for infinitesimal time t, we get the requirement. ... the adjoint A† is defined by the requirement. ⟨ϕ|A†|ψ⟩ = ⟨ψ|A|ϕ⟩.

31 May 2024: the requirement that no signal can travel faster than light. Our goal is to figure out.
