Dynamics of the Fermion-Rotor System
Vazha Loladze, Takemichi Okui, David Tong
We explore the dynamics of the fermion-rotor system, a simple impurity model in d=1+1 dimensions that consists of a collection of purely right-moving fermions interacting with a qu…
Monopole-Fermion Scattering and the Solution to the Semiton/Unitarity Puzzle
Vazha Loladze, Takemichi Okui
We study Polchinski's "fermion-rotor system" as an accurate description of charged Weyl fermions scattering on a magnetic monopole core in the limit of zero gauge coupling. Traditi…
Topics in gravity SCET: the diff Wilson lines and reparametrization invariance
Sabyasachi Chakraborty, Takemichi Okui, Arash Yunesi
Two topics in soft collinear effective theory (SCET) for gravitational interactions are explored. First, the collinear Wilson lines---necessary building blocks for maintaining mult…
Nonlinearly realized conformal invariance in scale invariant field theories
Takemichi Okui
Implications are explored of promoting non-conformal scale-invariant theories to conformal theories by nonlinearly realizing the missing symmetry. Properties of the associated Namb…
Soft collinear effective theory for gravity
Takemichi Okui, Arash Yunesi
We present how to construct a Soft Collinear Effective Theory (SCET) for gravity at the leading and next-to-leading powers from the ground up. The soft graviton theorem and decoupl…
The 't Hooft Model As A Hologram
Emanuel Katz, Takemichi Okui
We consider the 3d dual of 1+1 dimensional large-N_c QCD with quarks in the fundamental representation, also known as the 't Hooft model. 't Hooft solved this model by deriving a S…
