A bstract We explore the double copy of effective field theories (EFTs), in recently proposed generalized color-kinematics and Kawai-Lewellen-Tye (KLT) approaches. In former, we systematically construct scalar numerators satisfying Jacobi identities from simpler numerator seeds with trace-like permutation properties. This construction has advantage being easily applicable to any multiplicity, w...

Steven Weinberg's seminal papers from 1990-92 initiated the use of effective field theories (EFTs) for nuclei. We summarize progress, priorities, and open questions nuclear EFT developments based on 2019 INT program "Nuclear Structure at Crossroads."

Effective theories describing black hole exteriors resemble open quantum systems inasmuch as many unmeasurable degrees of freedom beyond the horizon interact with those we can see. A solvable Caldeira-Leggett type model a field that mixes unmeasured thermal on shared surface was proposed in arXiv:2106.09854 to provide benchmark against which more complete calculations might be compared. We here...

We explore the correspondence between geometric function theory (GFT) and quantum field (QFT). The crossing symmetric dispersion relation provides necessary tool to examine connection GFT, QFT, effective theories (EFTs), enabling us connect with crossing-symmetric EFT-hedron. Several existing mathematical bounds on Taylor coefficients of Typically Real functions are summarized shown be enormous...

We use the numerical S-matrix bootstrap method to obtain bounds on two leading Wilson coefficients of chiral lagrangian controlling low-energy dynamics massless pions thus providing a proof concept that can be used derive non-perturbative EFTs in more than spacetime dimensions.

High-dimensional time series increasingly arise in the Internet of Energy (IoE), given use multi-sensor environments and two way communication between energy consumers smart grid. Therefore, methods that are capable computing high-dimensional great value building IoE applications. Fuzzy Time Series (FTS) models stand out as data-driven non-parametric easy implementation high accuracy. Unfortuna...

A bstract Swampland criteria like the Weak Gravity Conjecture should not only apply to particles, but also other lower-codimension charged objects in 4d EFTs strings and membranes. However, description of latter is general subtle due their large backreaction effects. In context $$ \mathcal{N} N = 1 EFTs, we c...
