Measuring Lorentz Violation in Weak Gravity Fields
Zonghao Li
Many new linearized coefficients for Lorentz violation are discovered in our recent work on the construction of a generic Lorentz-violating effective field theory in curved spaceti…
Lorentz violation in the matter-gravity sector
Zonghao Li
We construct the general Lorentz-violating effective field theory in curved spacetime and the corresponding nonrelativistic Hamiltonian in the Earth's gravitational field. Applying…
Searches for beyond-Riemann gravity
Alan Kostelecky, Zonghao Li
Many effective field theories describing gravity cannot arise from an underlying theory based on Riemann geometry or its extensions to include torsion and nonmetricity but may inst…
Backgrounds in gravitational effective field theory
Alan Kostelecky, Zonghao Li
Effective field theories describing gravity coupled to matter are investigated, allowing for operators of arbitrary mass dimension. Terms violating local Lorentz and diffeomorphism…
