Why, at zero Kelvin, does an H2 molecule have only cylindrical, but not spherical, symmetry?

Treating the protons as Fermions, I would have expected the lowest energy state of H2 to have spherical symmetry, including in the distribution of the protons. Can it be shown that in going to...

How to correct present era FRW-type metrics to accommodate matter density fluctuations implied by CMB temperature fluctuations?

CMB temperature fluctuations of the order of a few parts per million imply matter density fluctuations of the same order at the time of recombination. But the Cosmological Principle implies a...

Does anyone know of an asymptotic expression for the expectation of the maximum of n samples drawn from a normal distribution as n -> infinity ?

T(n) := as n -> infinity, assuming the z are drawn from a unit variance zero mean normal distribution. Numerical efforts suggest T(n) ~ 0.5*ln(n) whereas I am...

How does mass renormalization work in an FRW spacetime?

In an FRW cosmology expressed in conformal coordinates the classical 'mechanical' action is as shown in the first image. The Dirac equation in conformal FRW spacetime is shown in the second image....
