By synchrotron infrared nanospectroscopy, we demonstrate modulation of momentum and group velocity of subdiffractional hyperbolic phonon-polaritons (HP2), in hexagonal boron nitride nanocrystals, by varying the SiO2 film ...

In this work we present the theoretical study on magnetic polaritons (magnon-polaritons) in a system formed by a semi-infinite gyromagnetic medium (ferromagnetic or antiferromagnetic), with a layer of graphene at the ...

Os fenômenos ópticos de cristais polares de van der Waals, em escala nanométrica, ocorrem majoritariamente via formação de poláritons, que são quasi-partículas originárias do acoplamento entre fótons e ressonâncias ...

The optics microcavity attract the attention of the scientic community for due to their large potential for applications in optoelectronic new generation devices. It is possible to insert a gain medium on it, as a simple ...

We investigate the multifractal properties for the spectra of plasmon–polaritons and light waves in multiple layers arranged in a quasiperiodic fashion. The profiles of the plasmon polariton bandwidths and the light ...

This dissertation aims to report the study of the polariton population dynamics derived from a quantum model for parametric oscillation. In this work we show the experimental results of the measurement of the oscillation ...

A theoretical study of mixed modes of uniaxial Heisenberg antiferromagnets by a dc field is presented. The static field is applied in an arbitrary direction relative to the easy axis and special attention is given to the ...

An exciton-polariton condensate (EPC) confined in a parabolic two-dimensional trap is considered theoretically. In the realistic limit of weakly interacting polaritons, the nonlinear term in the Gross-Pitaevskii equation ...
