Five dimensional Chern–Simons gravity for the expanded (anti)-de Sitter gauge group $${\hbox {C}}_5$$ C5

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We study the Hamiltonian dynamics of a five-dimensional Chern–Simons theory for the gauge algebra $$C_5$$ C5 of Izaurieta, Rodriguez and Salgado, the so-called $$\hbox {S}_H$$ SH -expansão of the 5D (anti-)de Sitter algebra (a)ds, based on the cyclic ...

Protective Effects of Socioeconomic Status and Lifestyle on Amyloid‐ and White Matter Hyperintensity‐Related Longitudinal Brain Atrophy and Cognitive Decline

open access: yesAnnals of Neurology, EarlyView.
Objective Socioeconomic status (SES) and lifestyle activities (LA) are strongly related, and both are associated with dementia risk. We investigated the influence of SES and LA on brain atrophy and cognitive decline considering amyloid‐beta (Aβ) positron emission tomography and white matter hyperintensity (WMH) load.

The complexity of some families of cycle-related graphs

open access: yesJournal of Taibah University for Science, 2017
In this paper, we derive new formulas for the number of spanning trees of a specific family of graphs – gear graphs, flower graphs, sun graphs and sphere graphs – using techniques from linear algebra, Chebyshev polynomials and matrix theory.

Relational Supersymmetry via the Dressing Field Method and Matter‐Interaction Supergeometric Framework

open access: yesAnnalen der Physik, EarlyView.
Applications of the Dressing Field Method are reviewed and further expanded to the very foundations of the supersymmetric framework, where it allows to build relational supersymmetric field theory. Furthermore, a novel approach is proposed giving a unified description of fermionic matter fields and bosonic gauge fields: a Matter‐Interaction ...

Vertex operator algebras, Higgs branches, and modular differential equations

open access: yesJournal of High Energy Physics, 2018
Every four-dimensional N=2 $$ \mathcal{N}=2 $$ superconformal field theory comes equipped with an intricate algebraic invariant, the associated vertex operator algebra.

Analytical Solutions of the Driven Time‐Dependent Jaynes–Cummings Model

open access: yesAnnalen der Physik, EarlyView.
Following the great strides made in the last decade towards the control and tunability of physical parameters in cavity quantum electrodynamics, this study presents new solutions to the dynamics of the time‐dependent Jaynes–Cummings model with variable external classical fields acting on the two‐level system and the quantized field mode.

From Triplet to Twist: The Photochemical E/Z‐Isomerization Pathway of the Near‐Infrared Photoswitch peri‐Anthracenethioindigo

open access: yesAngewandte Chemie International Edition, EarlyView.
The full photoisomerization mechanism of the all‐red‐light addressable peri‐anthracenethioindigo (PAT) has been decoded. Theory and transient absorption spectroscopy show that both E→Z$E\rightarrow Z$ and Z→E$Z\rightarrow E$ switching proceed via the triplet state.

Linear Matrix Inequality‐based design of distributed proportional‐integral‐derivative for the output consensus tracking in heterogeneous high‐order multi‐agent systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This article addresses the cooperative output consensus tracking problem for high‐order heterogeneous multi‐agent systems via a distributed proportional‐integral‐derivative (PID)‐like control strategy and proposes two novel control methodologies for the tuning of the control gains, which do not require any assumption and/or limitation on agent
