Effective Quantum Field Theories  

In General > s.a. Effective Field Theories; techniques in quantum field theory.
* Idea: Effective equations describe quantum corrections on the evolution of a state as the back-reaction of moments on the expectation values of the state.

Quantum Gravity > s.a. action for general relativity; formulations of general relativity; loop quantum cosmology; semiclassical quantum gravity.
* Requirements: If a theory is to be unitary and causal at high energies, at low energies the corresponding EFT operators must satisfy certain relations, known as positivity bounds; These relations can be used together with low-energy observations (cosmology, gravitational waves, etc) to learn something about the UV theory.
