| contents | The Belinksy-Khalatnikov-Lifshitz dynamics of gravity close to a spacelike singularity can be mapped, at each point in space separately, onto the motion of a particle bouncing within half the fundamental domain of the modular group. We show that the semiclassical quantisation of this motion is a conformal quantum mechanics where the states are constrained to be modular invariant. Each such state defines an odd automorphic $L$-function. In particular, in a basis of dilatation eigenstates the wavefunction is proportional to the $L$-function along the critical axis and hence vanishes at the nontrivial zeros. We show that the $L$-function along the positive real axis is equal to the partition function of a gas of non-interacting charged oscillators labeled by prime numbers. This generalises Julia's notion of a primon gas. Each state therefore has a corresponding, dual, primon gas with a distinct nontrivial set of chemical potentials that ensure modular invariance. We extract universal features of these theories by averaging the logarithm of the partition function over the chemical potentials. The averaging produces the Witten index of a fermionic primon gas. |
