On exact massless spinor quasibound states of Schwarzschild black hole

Physics Letters B
In the paper (D. Senjaya, 2024 [1]), the author investigated the massless spinor field in the Schwarzschild spacetime and derived an analytical solution expressed in terms of the Heun function. However, based on this approach, an incorrect expression for

Unas notas sobre la integración numérica del proceso de remodelación ósea Some notes on the numerical integration of bone remodeling process

Revista Cubana de Investigaciones Biomédicas, 2011
En este artículo se resuelve el problema de remodelación ósea propuesto por Weinans y otros. Para solucionar la ecuación de densidad se utilizan los métodos de Euler, Heun y Runge Kutta de cuarto orden.

Extremal Kerr–Newman black hole’s absence of charged scalar cloud

European Physical Journal C: Particles and Fields
The current work looks at the quasibound states and scalar cloud of relativistic charged scalar fields in an intense Kerr–Newman black hole. The absence of numerical techniques for solving the Klein–Gordon equation in the presence of extremal black holes

The Kerr–Bumblebee exact massive and massless scalar quasibound states and Hawking radiation

European Physical Journal C: Particles and Fields
In this letter, we will focus on the Klein–Gordon equation with rotating axially symmetric black hole solution of the Einstein–Bumblebee theory, so called the Kerr–Bumblebee black hole, as its 3 + 1 background space-time.

On Solutions of the Killingbeck Potential and Clarifying Comments on a Related Analytical Approach

East European Journal of Physics
The work presents analytical solutions to the Schrödinger equation for the Killingbeck potential, a hybrid model combining harmonic, linear, and Coulombic terms, as well as an approximate model of Yukawa-type potentials.

Generalized Heun and Lam��'s equations: factorization

, 2009
This paper addresses new results on the factorization of the general Heun's operator, extending the investigations performed in previous works [{\it Applied Mathematics and Computation} {\bf 141} (2003), 177 - 184 and {\bf 189} (2007), 816 - 820]. Both generalized Heun and generalized Lam equations are considered.

The effect of resummation on retarded Green’s function and greybody factor in AdS black holes

Journal of High Energy Physics
We investigate the retarded Green’s function and the greybody factor in asymptotically AdS black holes. Using the connection coefficients of the Heun equation, expressed in terms of the Nekrasov-Shatashvili (NS) free energy of an SU(2) supersymmetric ...
