Abstract
Dispersion dependences of electromagnetic waves in tryptophan crystals are constructed taking into account photon-axion conversion processes in the low-symmetry tryptophan crystal field. It is shown that a peculiarity associated with the intersection of dispersion curves of electromagnetic and axion waves appears in the frequency range of unitary polaritons, corresponding to the unity refractive index. In the intersection region, hybrid polariton-axion quasiparticles called axitons are formed. The dispersion relation for axitons in the visible and infrared spectral regions is derived. The conditions for photon-axion conversion near the exciton absorption edge of tryptophan in the ultraviolet spectral region are determined.
