Effective Field Theory for Extreme Mass Ratios
Clifford Cheung, Julio Parra-Martinez, Ira Z. Rothstein +2
We derive an effective field theory describing a pair of gravitationally interacting point particles in an expansion in their mass ratio, also known as the self-force (SF) expansio…
Apparent Fine Tunings for Field Theories with Broken Space-Time Symmetries
Alberto Nicolis, Ira Z. Rothstein
We exhibit a class of effective field theories that have hierarchically small Wilson coefficients for operators that are not protected by symmetries but are not finely tuned. These…
Dispersion Relations for Dislocation Modes and their Sensitivity to the Lattice Structure
Jin-Yun Lin, Shashin Pavaskar, Ira Z. Rothstein
In this letter we show that the dispersion relation for the dynamical modes of dislocations ("dislons") in solids is sensitive to the lattice symmetries. In particular, we show tha…
Snowmass Theory Frontier: Effective Field Theory
Matthew Baumgart, Fady Bishara, Tomas Brauner +34
We summarize recent progress in the development, application, and understanding of effective field theories and highlight promising directions for future research. This Report is p…
An Effective Field Theory of Magneto-Elasticity
Shashin Pavaskar, Riccardo Penco, Ira Z. Rothstein
We utilize the coset construction to derive the effective field theory of magnon-phonon interactions in (anti)-ferromagnetic and ferrimagnetic insulating materials. The action is u…
First Principles Prediction of the Landau Parameter for Fermi Liquids near the Unitarity Limit
Shashin Pavaskar, Ira Z. Rothstein
This paper explores the behavior of systems of cold fermions as they approach unitarity above the critical temperature. As we move away from unitarity, by decreasing the scattering…
