Loops in AdS: from the spectral representation to position space. Part II
Journal of High Energy Physics, 2021 We continue the study of AdS loop amplitudes in the spectral representation and in position space. We compute the finite coupling 4-point function in position space for the large-N conformal Gross Neveu model on AdS 3.

Effective field theory for magnetic compactifications
Journal of High Energy Physics, 2017 Magnetic flux plays an important role in compactifications of field and string theories in two ways, it generates a multiplicity of chiral fermion zero modes and it can break supersymmetry. We derive the complete four-dimensional effective action for N $$

Effective field theory of dissipative fluids
Journal of High Energy Physics, 2017 We develop an effective field theory for dissipative fluids which governs the dynamics of long-lived gapless modes associated with conserved quantities.

Effective field theory for non-relativistic hydrodynamics
Journal of High Energy Physics, 2020 We write down a Schwinger-Keldysh effective field theory for non-relativistic (Galilean) hydrodynamics. We use the null background construction to covariantly couple Galilean field theories to a set of background sources.

Consistency Relations in Effective Field Theory [PDF]
, 2017 The consistency relations in large scale structure relate the lower-order correlation functions with their higher-order counterparts. They are direct outcome of the underlying symmetries of a dynamical system and can be tested using data from future ...

Fab Four effective field theory treatment
European Physical Journal C: Particles and Fields, 2018 The article addresses the John interaction from Fab Four class of Horndeski models from the effective field theory point of view. Models with this interaction are heavily constrained by gravitational wave speed observations, so it is important to ...

Direct astrophysical tests of chiral effective field theory at supranuclear densities [PDF]
, 2020 Recent observations of neutron stars with gravitational waves and X-ray timing provide unprecedented access to the equation of state (EoS) of cold dense matter at densities difficult to realize in terrestrial experiments.

Halo Effective Field Theory of 6He
EPJ Web of Conferences, 2016 6He has a cluster structure with a tight 4He (α) core surrounded by two loosely bound neutrons (n) making it a halo nucleus. The leading-order (LO) Halo Effective Field Theory (EFT) [1, 2] calculations using momentum-space Faddeev equations pertinent to ...

Backgrounds in gravitational effective field theory [PDF]
, 2020 Effective field theories describing gravity coupled to matter are investigated, allowing for operators of arbitrary mass dimension. Terms violating local Lorentz and diffeomorphism invariance while preserving internal gauge symmetries are included.

Homotopy Transfer and Effective Field Theory I: Tree‐level [PDF]
Fortschritte der Physik, 2020 We use the dictionary between general field theories and strongly homotopy algebras to provide an algebraic formulation of the procedure of integrating out of degrees of freedom in terms of homotopy transfer. This includes more general effective theories
