Description
I will discuss Freund-Rubin compactifications of tachyon-free superstring theories that have no spacetime supersymmetry in their ten-dimensional formulation. A common feature of these models is the presence of scalar potentials in the low-energy physics, known as tadpole potentials, which correspond to vacuum energies in quantum field theories.
These tadpole potentials can play crucial roles in flux compactifications, and one can engineer Freund-Rubin vacua by balancing tree-level fluxes with one-loop vacuum energies. I will comment on the stability of these solutions and their connections with charged branes.
