Furthermore, we provide a comprehensive description of this anisotropic nonlinearity that is rooted in the microscopic symmetries of the crystal, and validate experi- mental results with numerical simulations, which show excellent agreement.enPlasmonicNanophotonicAnisotropic nonlinearities in crystalline gold and how to exploit themtext::objet présenté à une conférence::actes de conférence::article dans une conférence/papier de conférence
