Cosmological electromagnetic hopfions
Sergio A. Hojman, Felipe A. Asenjo
It is shown that any mathematical solution for null electromagnetic field knots in flat spacetime is also a null field knotted solution for cosmological electromagnetic fields. Thi…
Exact solutions to the Telegraph equation in terms of Airy functions
Felipe A. Asenjo, Sergio A. Hojman, Braulio M. Villegas-Martínez +2
Two exact different solutions to the Telegraph equation in three-dimensional space are obtained in terms of Airy functions. As a result, these solutions unveil a distinctive propag…
Time-domain supersymmetry for massless scalar and electromagnetic fields in anisotropic cosmologies
Felipe A. Asenjo, Sergio A. Hojman
It is shown that any cosmological anisotropic model produces supersymmetric theories for both massless scalar and electromagnetic fields. This supersymmetric theory is the time-dom…
Supersymmetric behavior of polarized electromagnetic waves in anisotropic media
Felipe A. Asenjo, Sergio A. Hojman, Braulio M. Villegas-Martínez +2
A medium with specific anisotropic refractive indices can induce a supersymmetric behavior in the propagation of polarized electromagnetic waves, in an analogue fashion to a quantu…
Abnormal light propagation and the underdetermination of theory by evidence in astrophysics
Felipe A. Asenjo, Sergio A. Hojman, Niels Linnemann +1
We investigate the propagation of certain non-plane wave solutions to Maxwell's equations in both flat and curved spacetimes. We find that such solutions (or rather parts of them)…
The Hurwitz-Hopf Map and Harmonic Wave Functions for Integer and Half-Integer Angular Momentum
Sergio A. Hojman, Eduardo Nahmad-Achar, Adolfo Sánchez-Valenzuela
Harmonic wave functions for integer and half-integer angular momentum are given in terms of the Euler angles that define a rotation in , and the Euclidean norm in…
