Abstract: (International Press)
For an arbitrary prime number pp, we propose an action for bosonic pp-adic strings in curved target spacetime, and show that the vacuum Einstein equations of the target are a consequence of worldsheet scaling symmetry of the quantum pp-adic strings, similar to the ordinary bosonic strings case. It turns out that spherical vectors of unramified principal series representations of PGL(2,Qp)PGL (2,\mathbb{Q}_p) are the plane wave modes of the bosonic fields on pp-adic strings, and that the regularized normalization of these modes on the padic worldsheet presents peculiar features which reduce part of the computations to familiar setups in quantum field theory, while also exhibiting some new features that make loop diagrams much simpler. Assuming a certain product relation, we also observe that the adelic spectrum of the bosonic string corresponds to the nontrivial zeros of the Riemann Zeta function.
