Circularly polarized periodic gravitational wave and the Pais-Uhlenbeck oscillator
Mahmut Elbistan
The "Bargmann framework" allows us to prove the equivalence of the Pais-Uhlenbeck oscillator with a spin-zero particle in a circularly polarized periodic gravitational wave. Pushin…
Marchenko method with incomplete data and singular nucleon scattering
Mahmut Elbistan, Pengming Zhang, Janos Balog
We apply the Marchenko method of quantum inverse scattering to study nucleon scattering problems. Assuming a type repulsive core and comparing our results to the Reid93 phe…
Neutron-proton scattering and singular potentials
Mahmut Elbistan, Pengming Zhang, Janos Balog
We consider a Bargmann-type rational parametrization of the nucleon scattering phase shifts. Applying Marchenko's method of quantum inverse scattering we show that the scattering d…
Optical helicity and Hertz vectors
Mahmut Elbistan
We study the conserved quantity associated with the dual symmetry of the Maxwell equations, called the optical helicity, by means of transverse Hertz vectors. In the presence of ch…
