WebIn the supergeometric formulation (as in, e.g, [ 1 ]), the path integral has rather straight forward generalizations to {\mathcal {N}}=1 and {\mathcal {N}}=2 supersymmetry. These correspond, on the index theory side, to the Gauss–Bonnet–Chern theorem and the Grothendieck–Riemann–Roch theorem. WebOct 10, 2024 · For Path II, we must take v2 = (D + d) / t. Keeping only terms of leading order in d / D, the action difference between the two paths S2 − S1 = mDd / t. so the phase difference S2 − S1 ℏ = mvd ℏ = 2πpd h = 2πd λ. This is the known correct result, and this fixes the constant multiplying the action/ h in the expression for the path ...
