S-duality in AdS/CFT magnetohydrodynamics
James Hansen, Per Kraus
We study the nonlinear hydrodynamics of a 2+1 dimensional charged conformal fluid subject to slowly varying external electric and magnetic fields. Following recent work on deriving…
Nonlinear Magnetohydrodynamics from Gravity
James Hansen, Per Kraus
We apply the recently established connection between nonlinear fluid dynamics and AdS gravity to the case of the dyonic black brane in AdS_4. This yields the equations of fluid dyn…
Generating Charge from Diffeomorphisms
James Hansen, Per Kraus
We unravel some subtleties involving the definition of sphere angular momentum charges in AdS_q \times S^p spacetimes, or equivalently, R-symmetry charges in the dual boundary CFT.…
The Predictive Power of Effective Field Theory in NN Scattering: ^3S_1-^3D_1 Mixing at Next-to Next-to Leading Order
Thomas D. Cohen, James M. Hansen
The convergence of the Q expansion in the ^3S_1-^3D_1 mixing angle is investigated through the renormalization condition used to fit the free paramteter encountered at NNLO. Althou…
Testing Low Energy Theorems in Nucleon-Nucleon Scattering
Thomas D. Cohen, James M. Hansen
Low energy theorems have been derived for the coefficients of the effective range expansion in s-wave nucleon-nucleon scattering valid to leading nontrivial order in an expansion b…
Systematic Power Counting in Cutoff Effective Field Theories for Nucleon-Nucleon Interactions and the Equivalence With PDS
Thomas D. Cohen, James M. Hansen
An analytic expression for the phase shifts in nucleon-nucleon scattering is derived in the context of the Schrödinger equation in configuration space with a short distan…
