A Material Frame: Hard Recoils from Slow Force Carriers
Francesco Serra
The paper proposes a modification of the Standard Model where the photon’s longitudinal component becomes a physical, ultra‑slow mode, breaking gauge and Lorentz invariance, and st…
Shadow sectors of gauge theories
Loris Del Grosso, David E. Kaplan, Francesco Serra
We show that both abelian and non-abelian gauge theories admit configurations in which the fields behave as if in the presence of static charge densities, or ``shadow charges". The…
A Precision Gyroscope from the Helicity of Light
Michael A. Fedderke, Roni Harnik, David E. Kaplan +4
We describe a gyroscope that measures rotation based on the effects of the rotation on the polarization of light. Rotation induces a differential phase shift in the propagation of…
Wrong Signs are Alright
David E. Kaplan, Surjeet Rajendran, Francesco Serra
It has been shown that some Lorentz-invariant quantum field theories, such as those with higher-dimensional operators with negative coefficients, lead to superluminality on some cl…
