Non-perturbative decay of non-Abelian hair

Journal of High Energy Physics, 2017
We construct a solution of Heterotic supergravity which interpolates between two different AdS3 × S3 × T4 geometries corresponding to the near-horizon limits of two 5-dimensional black holes, only one of which has non-Abelian hair.

D-dimensional Bardeen–AdS black holes in Einstein–Gauss–Bonnet theory

European Physical Journal C: Particles and Fields, 2019
We present a D-dimensional Bardeen like Anti-de Sitter (AdS) black hole solution in Einstein–Gauss–Bonnet (EGB) gravity, viz., Bardeen–EGB–AdS black holes.

Fixed-time and state-dependent time discontinuities in the theory of Stieltjes differential equations

Electronic Journal of Qualitative Theory of Differential Equations, 2022
In the present paper, we are concerned with a very general problem, namely the Stieltjes differential Cauchy problem involving state-dependent discontinuities.

Nonlocal Problems for Hilfer Fractional q-Difference Equations

Fractal and Fractional, 2023
In the paper, we investigate a kind of Hilfer fractional q-difference equations with nonlocal condition. Firstly, the existence and uniqueness results of solutions are obtained by using topological degree theory and Banach fixed point theorem ...

On the Existence and Applicability of Extremal Principles in the Theory of Irreversible Processes: A Critical Review

Energies, 2022
A brief review of the development of ideas on extremal principles in the theory of heat and mass transfer processes (including those in reacting media) is given. The extremal principles of non-equilibrium thermodynamics are critically examined.

De-singularizing the extremal GMGHS black hole via higher derivatives corrections

Physics Letters B, 2021
The Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) black hole is an influential solution of the low energy heterotic string theory. As it is well known, it presents a singular extremal limit.

Observations on holographic aspects of four-dimensional asymptotically flat N $$ \mathcal{N} $$ = 2 black holes

Journal of High Energy Physics, 2022
In this note, we explore holographic attributes of four-dimensional near-extremal Reissner-Nordstrom black hole solutions in ungauged N $$ \mathcal{N} $$ = 2 supergravity theories at the two-derivative level by recasting them as a specific first-order ...

Flows of rotating extremal attractor black holes

Journal of High Energy Physics, 2023
We investigate the attractor mechanism of five-dimensional extremal rotating black holes in Einstein gravity minimally coupled with a multiplet complex scalar.

Conformal bootstrap deformations

Journal of High Energy Physics, 2022
We explore the space of extremal functionals in the conformal bootstrap. By recasting the bootstrap problem as a set of non-linear equations parameterized by the CFT data, we find an efficient algorithm for converging to the extremal solution ...

On a coupled system under coupled integral boundary conditions involving non-singular differential operator

AIMS Mathematics, 2023
In this work, a coupled system under coupled integral boundary conditions with Caputo-Fabrizio derivative (CFD) is considered. We intend to derive some necessary and sufficient results for the existence of at least one solution.
