Flux compactifications of type II string theory One of the (many) open problems in string theory is to construct a realistic solution (vacuum) of the theory that reproduces the physics of our four-dimensional universe including particle phenomenology and cosmological features. To this end, a lot of work has been dedicated to studying flux compactifications of ten-dimensional type II superstring theories on certain six-dimensional compact manifolds with background fluxes turned on. Although we haven’t been able to construct a fully consistent realistic vacuum solution yet, significant progress has been made in reproducing many important features of particle physics (e.g., matter content) as well as cosmological features such as a small positive cosmological constant in accordance with observation.
