| contents | In the present work, we introduce a new interpretation of exciton binding energies in two-dimensional (2D) materials using concepts from brane physics. We adapt the Dvali-Gabadadze-Porrati-Shifman mechanism to a (2+1)-dimensional brane in a (3+1)-D spacetime, deriving an effective electromagnetic potential on the brane. Using this potential, we develop a hydrogenic model for exciton binding energies in 2D materials, applying it to s-type excitons and comparing theoretical predictions with experimental results on WS$_{2}$ monolayers. This interdisciplinary approach bridges high-energy and condensed matter physics, offering a new didactic representation of excitons in low-dimensional systems. |
