Description

In this talk, we aim to present a Hamiltonian formulation for the interior perturbations of the Schwarzschild spacetime. Our analysis is based on a truncated action at quadratic order in perturbations. Both background and perturbative degrees of freedom are treated dynamically, forming a unified system endowed with the canonical structure derived from the truncated action. First-order perturbations of the metric are expressed through perturbative gauge-invariants, linear perturbative constraints, and their associated canonical variables. For the quantum description, we employ a hybrid approach: the background is quantized using loop quantum gravity techniques, while the perturbations are treated with conventional quantum field methods.
