Some aspects of Skyrme–Chern–Simons densities [PDF]
Journal of Physics A: Mathematical and Theoretical, 2021 The gauge transformation properties of the Skyrme–Chern–Simons (SCS) densities is studied. Two types of SCS actions are identified, typeI in which the gauge group is smaller than the largest possible one, and typeII which are gauged with the largest ...

Connection between cosmological time and the constants of nature [PDF]
Physical Review D, 2021 We examine in greater detail the proposal that time is the conjugate of the constants of nature. Fundamentally distinct times are associated with different constants, a situation often found in “relational time” settings. We show how in regions dominated

Conformal Interactions Between Matter and Higher‐Spin (Super)Fields
Fortschritte der Physik, Volume 71, Issue 1, January 2023., 2023 Abstract In even spacetime dimensions, the interacting bosonic conformal higher‐spin (CHS) theory can be realised as an induced action. The main ingredient in this definition is the model S[φ,h]$\mathcal {S}[\varphi ,h]$ describing a complex scalar field φ coupled to an infinite set of background CHS fields h, with S[φ,h]$\mathcal {S}[\varphi ,h ...

Phonon Engineering of Micro‐ and Nanophononic Crystals and Acoustic Metamaterials: A Review
Small Science, Volume 3, Issue 1, January 2023., 2023 Phononic crystals and acoustic metamaterials with phonon wave manipulation capabilities have attracted considerable attention. This review summarizes the progress and identifies gaps in phonon engineering at the micro‐ and nanoscales using phononic crystals and metamaterials due to their potential significance in modern electronic applications.

On a k-th Gauduchon almost Hermitian manifold
Complex Manifolds, 2022 We characterize the k-th Gauduchon condition and by applying its characterization, we reprove that a compact k-th Gauduchon, semi-Kähler manifold becomes quasi-Kähler, which tells us that in particular, a compact almost pluriclosed, semi-Kähler manifold ...

Berry Phase, Berry Connection, and Chern Number for a Continuum Bianisotropic Material From a Classical Electromagnetics Perspective [PDF]
IEEE Journal on Multiscale and Multiphysics Computational Techniques, 2016 The properties that quantify photonic topological insulators (PTIs), Berry phase, Berry connection, and Chern number, are typically obtained by making analogies between classical Maxwell's equations and the quantum mechanical Schrödinger equation ...

Estimates for a function on almost Hermitian manifolds
Complex Manifolds, 2021 We study some estimates for a real-valued smooth function φ on almost Hermitian manifolds. In the present paper, we show that ∂∂∂̄ φ and ∂̄∂∂̄ φ can be estimated by the gradient of the function φ.

Localization and duality for ABJM latitude Wilson loops
Journal of High Energy Physics, 2021 We investigate several aspects of BPS latitude Wilson loops in gauge theories in three dimensions with N $$ \mathcal{N} $$ ≥ 4 supersymmetry. We derive a matrix model for the bosonic latitude Wilson loop in ABJM using supersymmetric localization, and ...

Chern-Simons Origin of Superstring Integrability. [PDF]
Physical Review Letters, 2020 We derive the AdS_{5}×S^{5} Green-Schwarz superstring from four-dimensional Beltrami-Chern-Simons theory reduced on a manifold with singular boundary conditions.
