Research Fields
Enter a research area through its central questions, characteristic observables, methods, and literature. The field guides connect topics across QFT so that you can identify useful background and a path into a problem.
Evidence cutoff. The guides synthesize sources available through 11 August 2026. Each guide states the source selection and scope of its assessment.
Fields and their central questions
Section titled “Fields and their central questions”| If your starting question is about… | Begin with |
|---|---|
| collider observables, amplitudes, or perturbative accuracy | Amplitudes and precision scattering |
| indirect tests of heavy new physics | EFT and tests of the Standard Model |
| confinement, spectra, topology, or strong coupling | Nonperturbative gauge dynamics |
| regulator-to-continuum numerical evidence | Lattice and Hamiltonian field theory |
| crossing symmetry, operator data, or CFT classification | Conformal field theory and bootstrap |
| protected quantities or strong–weak equivalences | Supersymmetry and duality |
| thermal matter, transport, or real-time evolution | Thermal and nonequilibrium field theory |
| critical, topological, fractionalized, or synthetic matter | Quantum matter and emergence |
| entanglement, channels, modular structure, or scrambling | Quantum information and entanglement in QFT |
| quantum fields on curved backgrounds or semiclassical backreaction | QFT in curved spacetime and semiclassical gravity |
| bulk reconstruction, black holes, or gravitational path integrals | Holography and quantum gravity |
| theorem-level existence, reconstruction, or equivalence | Mathematical and constructive QFT |
Connections across fields
Section titled “Connections across fields”A lattice computation of a thermal equation of state connects lattice methods, thermal physics, and the finite-temperature QCD evidence comparison. Follow those connections while keeping each claim’s observable and assumptions explicit. A supersymmetric benchmark, for example, need not support the same conclusion in a nonsupersymmetric theory.
The questions chapter examines specific unresolved problems; methods compares techniques; evidence brings together concrete results.
Coverage
Section titled “Coverage”Dedicated guides to nuclear structure, astroparticle phenomenology, cosmological data analysis, perturbative gravity, string phenomenology, and quantum-optics implementations are not yet included. Their QFT foundations remain in the Library, and related research appears within the programs above.
