In a thermal graviton bath the light-cone support of a scalar commutator is Gaussian with variance Var(x^{2})=16 G_N T t^{3}/3 after vacuum subtraction.
Any stand-alone dissipative hydrodynamic EFT is acausal; causal UV completions exist that preserve the exact IR hydrodynamic mode for subluminal sound speed and finite gradient-expansion radius.
Defines IR-finite amplitudes M_E that preserve analyticity and unitarity to derive positivity bounds on EFTs including electromagnetism and gravity in D=4.
Derives gauge-invariant influence functionals for photons and Stueckelberg fields in open U(1) gauge EFTs via BRST on the in-in contour after integrating out matter.
