TL;DR: In this article, it was shown that molecular ordering in the isotropic phase of MBBA can be induced by an intense laser field and the ordering relaxation time as a function of temperature.

TL;DR: The physical origins of the surface nonlinear susceptibility responsible for surface optical second-harmonic generation were investigated in this article, where experiments performed on simple covalent systems were designed to distinguish between the nonlocal electric-quadrupole-type nonlinearity induced by field discontinuity and the local intrinsic, electric-dipole type nonlinearities of a surface or interface.

TL;DR: In this article, a bright, broadband photoluminescence is observed from graphene at frequencies well above the excitation frequency, which arises from radiative recombination of a broad distribution of nonequilibrium electrons and holes, generated by rapid scattering between photoexcited carriers within tens of femtoseconds after the optical excitation.

TL;DR: The study demonstrates the unusual and tunable coupling between 2D graphene plasmons and domain-wall solitons and exhibits a peculiar dependence on electrostatic gating.
