| Abstract: |
A generalized entropy functional for $f(Q)$ gravity is derived by adapting the Noether charge formalism to the nonmetricity-based gravitational Lagrangian. The resulting functional, $S = \frac{1}{4} \int _H d^2x \, h \, f(Q)$ generalizes the Bekenstein?Hawking law and is shown to be consistent with the first law of entanglement thermodynamics. This consistency establishes a direct link between the modification of the gravitational action and the entanglement structure of spacetime, providing a robust thermodynamic and quantum information?theoretic interpretation for $f(Q)$ gravity |
