New Physics Hiding at the Ends
Clifford Cheung, Ira Z. Rothstein
Is field space infinite? If not, it either loops back on itself or ends altogether. Periodic boundary conditions are of course familiar, but field space endpoints--which appear in…

Gravitational Scattering and Beyond from Extreme Mass Ratio Effective Field Theory
Clifford Cheung, Julio Parra-Martinez, Ira Z. Rothstein +2
We explore a recently proposed effective field theory describing electromagnetically or gravitationally interacting massive particles in an expansion about their mass ratio, also k…

First Principle Predictions for Cold Fermionic Gases Near Criticality via Critical Boson Dominance and Anomaly Matching
Shashin Pavaskar, Ira Z. Rothstein
Recently the authors have developed an effective field theory formalism to systematically describe cold fermionic gases near the unitary limit. The theory has enhanced predictive p…
