Wilsonian effective potentials and closed string field theory
We investigate Wilsonian effective field theory as a model for the construction to be universal features. We find that the effective field theory contains the same less efficiently as the distance...

On-Shell Recursion Relations for Effective Field Theories
We derive the first ever on-shell recursion relations applicable to effective field theories. Based solely on factorization and the soft behavior of amplitudes scattering amplitudes in the nonlinear sigma model, Dirac-Born-...

Classical algebraic structures in string theory effective actions
We study generic properties of string theory effective actions obtained by classically integrating out massive excitations from string field theories based on cyclic bosonic string using Witten’s open string fi...

Effective Field Theories from Soft Limits of Scattering Amplitudes
We derive scalar effective field theories-Lagrangians, symmetries, and all-from to derive Lagrangians for each theory. We propose a natural classification of all scalar effective field theorie...

Improved action for contact effective field theory
We present an improved action for renormalizable effective field theories (EFTs can be used to improve the theory's convergence, to simplify its applications, and to connect it to phenomenological models. We exempl...

Mapping between Witten and lightcone string field theories
We propose a transformation between the off-shell field variables of Witten’s open bosonic string field theory and the traditional lightcone string field theory and Kikkawa’s lightcone string field

Calculations for nuclear matter and finite nuclei within and beyond energy-density-functional theories through interactions guided by effective field theory
We propose a novel idea to construct an effective interaction under energy-density-functional (EDF) theories which is adaptive to the enlargement of the model space. Guided by effective field theory princi...

Coulomb repulsion and correlation strength in LaFeAsO from density functional and dynamical mean-field theories
The role of electronic correlations in LaFeAsO is assessed using effective Hubbard Hamiltonian obtained from density functional calculations. It is shown that the on-site interaction parameters depend strongly on the choice of the single-par...
