Intersecting brane models realise four-dimensional physics by embedding stacks of D-branes at angles within higher-dimensional orientifold compactifications. Gauge symmetries arise from open strings ...

Branes are multidimensional objects that arise in the formulation of string theory. Finding more general ways to describe these objects mathematically often leads to new insights into string theory ...

String theory and its extensions propose that the elementary constituents of matter are not point particles but one-dimensional strings whose vibrational modes manifest as observed particles and ...

You may have heard the usual pop psy description of string theory. There are these tiny vibrating strings, and that's where all the force's particles, including gravity, in the entire universe come ...
