Low-energy Earth–Moon transfers via Theory of Functional Connections and homotopy
Numerous missions leverage the weak stability boundary in the Earth–Moon–Sun system to achieve a safe and cost-effective access to the lunar...

Orbit transfer using Theory of Functional Connections via change of variables
This work shows that a class of astrodynamics problems subject to mission constraints can be efficiently solved using the Theory of Functional...

Fast 2-impulse non-Keplerian orbit transfer using the Theory of Functional Connections
This study applies a new approach, the Theory of Functional Connections (TFC), to solve the two-point boundary-value problem (TPBVP) in non-Keplerian...

A generalized 4d Chern-Simons theory
A generalization of the 4d Chern-Simons theory action introduced by Costello and Yamazaki is presented. We apply general arguments from symplectic...

The geometric νSMEFT: operators and connections
We write down a geometric realization of the Standard Model Effective Field Theory (SMEFT) extended by n f flavours of light sterile neutrinos, a...

Insight into the structural, elastic, optoelectronic, and thermodynamic properties of GaXF3 (X = Se, Si) via density functional theory
The pursuit of new materials with tailored properties is essential for advancing technology. This research focuses on GaXF 3 (X = Se, Si)...

3 definitions of BF theory on homology 3-spheres
3-dimensional BF theory with gauge group G (= Chern-Simons theory with non-compact gauge group TG ) is a deceptively simple yet subtle topological...

Relativistic Density-Functional Theories
This chapter introduces the relativistic density-functional theory in nuclear physics. After a brief introduction on the history, advantages, and...

Four dimensional topological supergravities from transgression field theory
In this work, we propose a four-dimensional gauged Wess-Zumino-Witten model, obtained as a dimensional reduction from a transgression field theory...

Two string theory flavours of generalised Eisenstein series
Generalised Eisenstein series are non-holomorphic modular invariant functions of a complex variable, τ , subject to a particular inhomogeneous Laplace...

Addressing energy density functionals in the language of path-integrals II: comparative study of functional renormalization group techniques applied to the (0+0)-D O(N)-symmetric \(\varphi ^{4}\)-theory
The present paper is the second of a series of publications that aim at investigating relevant directions to turn the nuclear energy density...

Network Theory
Dynamical and adaptive networks are the backbone of many complex systems. Examples range from ecological prey–predator networks to the gene...

Two-Dimensional Ferronematics, Canonical Harmonic Maps and Minimal Connections
We study a variational model for ferronematics in two-dimensional domains, in the “super-dilute” regime. The free energy functional consists of a...

Note on the bundle geometry of field space, variational connections, the dressing field method, & presymplectic structures of gauge theories over bounded regions
In this note, we consider how the bundle geometry of field space interplays with the covariant phase space methods so as to allow to write results of...

Phase-space analysis of a novel cosmological model in f(Q) theory
The vanishing affine connections have been used solely while adopting the modified f ( Q ) gravity theory to the cosmology. Consequently, researchers...

Rigor with machine learning from field theory to the Poincaré conjecture
Despite their successes, machine learning techniques are often stochastic, error-prone and blackbox. How could they then be used in fields such as...

The Philosophy of Causal Set Theory
This chapter presents the most interesting philosophical issues as they arise in causal set theory. The first concerns the apparent disappearance of...

Functional Characteristics of Electric Contact Grease
Abstract —The article notes that the use of electric contact grease is one of the effective methods for improving the reliability of connections in...

Anisotropic compactification of nonrelativistic M-theory
We study a decoupling limit of M-theory where the three-form gauge potential becomes critical. This limit leads to nonrelativistic M-theory coupled...
