European Physical Journal C: Particles and Fields, 2021 We generalize our previous studies on the Maxwell quasinormal modes around Schwarzschild-anti-de-Sitter black holes with Robin type vanishing energy flux boundary conditions, by adding a global monopole on the background.

U(1) Noncommutative Gauge Fields and Magnetogenesis [PDF]
, 2005 The connection between the Lorentz invariance violation in the lagrangean context and the quantum theory of noncommutative fields is established for the U(1) gauge field.

Symmetries of Heterotic String Theory [PDF]
, 1995 We study the symmetries of the two dimensional Heterotic string theory by following the approach of Kinnersley et al for the study of stationary-axially symmetric Einstein-Maxwell equations. We identify the finite dimensional groups $G'$ and $H'$ for the

Spinor-Like Hamiltonian for Maxwellian Optics
EPJ Web of Conferences, 2016 Background. Spinors are more special objects than tensors. Therefore spinors possess more properties than the more generic objects such as tensors. The group of Lorentz two-spinors is the covering group of the Lorentz group. Purpose.

Exact Solutions of Maxwell Equations in Homogeneous Spaces with the Group of Motions G3(IX)
Axioms, 2023 This paper classifies the exact solutions of the Maxwell vacuum equations for the case when the electromagnetic fields and metrics of homogeneous spaces are invariant with respect to the motion group G3(IX).

Rotation induced in a coil moving in an electric field [PDF]
Revista Brasileira de Ensino de Física, 2021 The integral form of the fourth Maxwell’s equation is often written in two different ways: in the first, the partial derivative of Electric field appears, while the second contains a time derivative of electric flux integral.

Towards the deformation quantization of linearized gravity [PDF]
, 2004 We present a first attempt to apply the approach of deformation quantization to linearized Einstein's equations. We use the analogy with Maxwell equations to derive the field equations of linearized gravity from a modified Maxwell Lagrangian which allows

Derivation of the Zakharov equations [PDF]
, 2005 This paper continues the study of the validity of the Zakharov model describing Langmuir turbulence. We give an existence theorem for a class of singular quasilinear equations. This theorem is valid for well-prepared initial data. We apply this result to

Some Classical Models of Particles and Quantum Gauge Theories
Quantum Reports, 2022 The article contains a review and new results of some mathematical models relevant to the interpretation of quantum mechanics and emulating well-known quantum gauge theories, such as scalar electrodynamics (Klein–Gordon–Maxwell electrodynamics), spinor ...
