Logarithmic gravity model
S. I. Kruglov
The modified gravity theory with the function is studied. The action at small coupling becomes Einstein--Hilbert action. The bound on the paramete…
NED-AdS black holes, extended phase space thermodynamics and Joule--Thomson expansion
S. I. Kruglov
We study and discuss the critical behavior of charged by nonlinear electrodynamics (NED) AdS black holes in an extended phase space. The negative cosmological constant is treated a…
Modified Gibbs's representation of rotation matrix
S. I. Kruglov, V. Barzda
A modified Gibbs's rotation matrix is derived and the connection with the Euler angles, quaternions, and CayleyKlein parameters is established. As particular cases, the Rodrigue…
Notes on Born-Infeld-type electrodynamics
S. I. Kruglov
We propose a new model of nonlinear electrodynamics with three parameters. Born-Infeld electrodynamics and exponential electrodynamics are particular cases of this model. The pheno…
Wave Function of the Universe from a Matrix Valued First-Order Formalism
Sergey I. Kruglov, Mir Faizal
In this paper, the Wheeler-DeWitt equation in full superspace formalism will be written in a matrix valued first-order formalism. We will also analyse the Wheeler-DeWitt equation i…
Deformation of the Dirac Equation
Mir Faizal, Sergey I. Kruglov
In this paper, we will first clarify the physical meaning of having a minimum measurable time. Then we will combine the deformation of the Dirac equation due to the existence of mi…
