In a layered and strongly anisotropic superconductor. the hybrid modes provided by the propagation of electromagnetic waves in the matter identify two well-separated energy scales connected to the large in-plane plasma frequency and to the soft out-of-plane Josephson plasmon. Despite wide interest in their detection and manipulation by means of different experimental protocols. the ph... https://parisnaturalfoodes.shop/product-category/castor-oil/
