Hydrogen supersymmetry: A new method in perturbation theory
E. A. Muljarov
The O(4) supersymmetry of the hydrogen atom is utilized to construct a complete basis using only the bound state wave functions. For a large class of perturbations, an expansion of…
Resonant acousto-optics in the terahertz range: TO-phonon polaritons driven by an ultrasonic wave
E. A. Muljarov, R. H. Poolman, A. L. Ivanov
The resonant acousto-optic effect is studied both analytically and numerically in the terahertz range where the transverse-optical (TO) phonons play the role of a mediator which st…
Ultrasonic control of terahertz radiation via lattice anharmonicity in LiNbO3
R. H. Poolman, E. A. Muljarov, A. L. Ivanov
We propose a novel tunable terahertz (THz) filter using the resonant acousto-optic (RAO) effect. We present a design based on a transverse optical (TO) phonon mediated interaction…
Brillouin-Wigner perturbation theory in open electromagnetic systems
E. A. Muljarov, W. Langbein, R. Zimmermann
A Brillouin-Wigner perturbation theory is developed for open electromagnetic systems which are characterised by discrete resonant states with complex eigenenergies. Since these sta…
