Fractional oscillators with fractional damping in the presence of external forces
Fernando Olivar-Romero, Oscar Rosas-Ortiz
We investigate how a fractional oscillator reacts to external forces when the dynamic law includes a damping term that is explicitly fractional. The corresponding three-parametric…
Bessel-Gauss beams of arbitrary integer order: propagation profile, coherence properties and quality factor
S. Cruz y Cruz, Z. Gress, P. Jimenez-Macias +1
We present a novel approach to generate Bessel-Gauss modes of arbitrary integer order and well-defined optical angular momentum in a gradient index medium of transverse parabolic p…
Exact solutions for vector phase matching conditions in nonlinear uniaxial crystals
Juan Lopez-Duran, Oscar Rosas-Ortiz
The strongly transcendental equations of vector phase matching are transformed into a fourth order polynomial equation that admits analytical solution. The real roots of this equat…
Theory of Photon Subtraction for Two-Mode Entangled Light Beams
Oscar Rosas-Ortiz, Kevin Zelaya
Photon subtraction is useful to produce nonclassical states of light addressed to applications in photonic quantum technologies. After a very accelerated development, this techniqu…
Balanced Gain-and-Loss Optical Waveguides: Exact Solutions for Guided Modes in Susy-QM
Sara Cruz y Cruz, Alejandro Romero-Osnaya, Oscar Rosas-Ortiz
The construction of exactly solvable refractive indices allowing guided TE modes in optical waveguides is investigated within the formalism of Darboux-Crum transformations. We appl…
Exact solutions for time-dependent non-Hermitian oscillators: classical and quantum pictures
Kevin Zelaya, Oscar Rosas-Ortiz
We associate the stationary harmonic oscillator with time-dependent systems exhibiting non-Hermiticity by means of point transformations. The new systems are exactly solvable, with…
