Puff Field Theory

Ori Ganor

UC Berkeley

“Puff Field Theory” is a string-theoretic construction of a nonlocal QFT where fundamental particles “puff-up” to occupy a three-dimensional volume. This theory is not Lorentz invariant, but Lorentz invariance is restored in the IR limit. The supergravity dual of Puff Field Theory has peculiar properties near the boundary, such as infinite redshift in frequency combined with infinite blueshift in wavelength. The theory, its properties and their implication will be discussed in the talk.
