Semiclassical formula for the number variance of the Riemann zeros
... Over the whole range 0 S L 1000 the largest difference between the ‘exact’ and semiclassical variances is 0.003 (over the range 0 6 L S 100 it is 0.002). It therefore appears that semiclassical theory gives a uniformly accurate description of the correlations in the heights of the zeros in both the ...

... Why? When they roll off center, they self-correct: say they roll to the left, then the wider part of the left cup and the narrower part of the right cup are on the tracks, causing rolling back to the right, since the left cup has larger tangential speed. Railroad wheels act on this same principle! ...

CENTRAL FORCE PROBLEMS

Though classical mechanics provides a well developed “theory of collisions,” the central force problem—our present concern—was conceived by Newton to involve instantaneous action at a distance, a concept to which many of his contemporaries (especial ...

Computing with Highly Mixed States
... When two mixed states have distinct density matrices (say ρ1 and ρ2 ), it is natural to ask how well they can be distinguished by a measurement. The answer is that the least-error measurement is one that measures in the basis that diagonalizes ρ1 − ρ2 . The success probability is proportional to the ...

Quantum-classical correspondence in the hydrogen atom in weak

In this work we show that the accuracy of the classical results does indeed rest on a particularly direct connection between classical and quantum predictions, and we demonstrate explicitly that in the perturbative limit the quantum expectation values of the angular momentum and the RungeLenz vector ...
