tests/test_negative_energy.py::test_qi_violation[0.6] PASSED

μ = 0.30: I_polymer - I_classical = -456.85

Theory Overview

This work extends Loop Quantum Gravity (LQG) to include matter fields quantized on a discrete polymer background. The key innovation is that the discrete nature of the polymer representation allows for:

• Stable Negative Energy: The polymer commutation relations modify the uncertainty principle, permitting longer-lived negative energy densities.
• Warp Bubble Formation: These negative energy regions can be configured to create stable warp bubble geometries.
• Ford-Roman Violation: The discrete field algebra allows violation of classical quantum inequalities over extended time periods.
