Energy loss at zero temperature from extremal black holes

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Using the AdS/CFT correspondence, we probe the extremal black holes by studying the energy loss of a moving heavy point particle in a strongly-coupled boundary field theory at zero temperature and finite charge density. We first consider the extremal AdS-

Second-order complex linear differential equations with special functions or extremal functions as coefficients

open access: yesElectronic Journal of Differential Equations, 2015
The classical problem of finding conditions on the entire coefficients A(z) and B(z) guaranteeing that all nontrivial solutions of $f''+A(z)f'+B(z)f=0$ are of infinite order is discussed. Two distinct approaches are used.

On the Boundary of Incidence Energy and Its Extremum Structure of Tricycle Graphs

open access: yesFrontiers in Physics, 2020
With the wide application of graph theory in circuit layout, signal flow chart and power system, more and more attention has been paid to the network topology analysis method of graph theory.

The black hole weak gravity conjecture with multiple charges

open access: yesJournal of High Energy Physics, 2020
We study the effect of higher-derivative corrections on asymptotically flat, four-dimensional, dyonic black holes in low-energy models of gravity coupled to N U(1) gauge fields.

Three-point functions in N $$ \mathcal{N} $$ = 4 SYM at finite N c and background independence

open access: yesJournal of High Energy Physics, 2020
We compute non-extremal three-point functions of scalar operators in N $$ \mathcal{N} $$ = 4 super Yang-Mills at tree-level in g YM and at finite N c , using the operator basis of the restricted Schur characters.

A New Dependence Condition for Time Series and the Extremal Index of Higher-Order Markov Chains

open access: yesRevstat Statistical Journal, 2006
We present a new dependence condition for time series and extend the extremal types theorem. The dependence structure of a stationary sequence is described by a sequence of extremal functions.

Logarithmic corrections to black hole entropy in matter coupled N $$ \mathcal{N} $$ ≥ 1 Einstein-Maxwell supergravity

open access: yesJournal of High Energy Physics, 2021
We calculate the first three Seeley-DeWitt coefficients for fluctuation of the massless fields of a N $$ \mathcal{N} $$ = 2 Einstein-Maxwell supergravity theory (EMSGT) distributed into different multiplets in d = 4 space-time dimensions.
