Loops in AdS: from the spectral representation to position space. Part II

open access: yesJournal 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 [PDF]

open access: yes, 2008
I give a brief review of effective field theory, disscussing the contribution of Feza G rsey in particular and focusing on the literature I am most familiar with.

Chern-Simons-matter theories at large baryon number

open access: yesJournal of High Energy Physics, 2021
We study SU(2) Chern-Simons theories at level k coupled to a scalar on T 2 × ℝ at large baryon number. We find a homogeneous but anisotropic ground state configuration for any values of k on the IR fixed-point of those models.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Soft bootstrap and effective field theories

open access: yesJournal of High Energy Physics, 2019
The soft bootstrap program aims to construct consistent effective field theories (EFT’s) by recursively imposing the desired soft limit on tree-level scattering amplitudes through on-shell recursion relations.

The hypertriton in effective field theory [PDF]

open access: yesNuclear Physics A, 2002
Doublet Lambda d scattering and the hypertriton are studied in the framework of an effective field theory for large scattering lengths. As in the triton case, consistent renormalization requires a one-parameter three-body force at leading order whose renormalization group evolution is governed by a limit cycle.

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Spin-charge separation for paired Dirac fermions in (1 + 1) dimensions

open access: yesJournal of High Energy Physics
We study Dirac fermions at finite density coupled to a complex pairing field assumed to obey scalar field theory with quartic self-repulsion. The bulk of our work develops the mathematics that elucidates the propagation of fermionic excitations in such ...
