Beryllium-9 in cluster effective field theory
SciPost Physics Proceedings, 2020 We study the 9 Be ground-state energy with non-local αn and αα potentials derived from Cluster Effective Field Theory. The short-distance dependence of the interaction is regulated with a momentum cutoff.

An effective field theory of magneto-elasticity
SciPost Physics, 2022 We utilize the coset construction to derive the effective field theory of magnon-phonon interactions in (anti)-ferromagnetic and ferrimagnetic insulating materials.

Baryonic effective field theory for light hypernuclei [PDF]
EPJ Web of Conferences, 2022 Light hypernuclei containing one or two Λ baryons are the subject of an ongoing experimental campaign aiming to study the spectrum of these systems, as well as the 2 and 3-body interaction between Λ hyperons and nucleons.

Small-x factorization from effective field theory
Journal of High Energy Physics, 2023 We derive a factorization theorem that allows for resummation of small-x logarithms by exploiting Glauber operators in the soft collinear effective field theory.

Effective field theories and inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2003 We investigate the possible influence of very-high-energy physics on inflationary predictions focussing on whether effective field theories can allow effects which are parametrically larger than order H^2/M^2, where M is the scale of heavy physics and H is the Hubble scale at horizon exit.

Effective field theories with instantons [PDF]
Nuclear Physics B, 1994 We explain how nonperturbative effects can be systematically included when constructing an effective field theory. We concentrate in particular on the matching calculation, by which a low energy theory without a heavy particle degree of freedom is matched onto the full theory.

Chiral kinetic theory from effective field theory revisited
Journal of High Energy Physics, 2019 We revisit the chiral kinetic equation from high density effective theory approach, finding a chiral kinetic equation differs from counterpart derived from field theory in high order terms in the O(1/μ) expansion, but in agreement with the equation ...

Gauge and General Coordinate Invariance in Non-Polynomial Closed String Field Theory [PDF]
Nucl.Phys.B380:103-127,1992, 1991 An appropriate field configuration in non-polynomial closed string field theory is shown to correspond to a general off-shell field configuration in low energy effective field theory. A set of string field theoretic symmetries that act on the fields in low energy effective field theory as general coordinate transformation and antisymmetric tensor gauge
