Nonlinear optical response of doped mono- and bilayer graphene: length gauge tight-binding model
F. Hipolito, Alireza Taghizadeh, T. G. Pedersen
We compute the nonlinear optical response of doped mono- and bilayer graphene using the full dispersion based on tight-binding models. The response is derived with the density matr…

Second harmonic spectroscopy to optically detect valley polarization in 2D materials
F. Hipolito, Vitor M. Pereira
Valley polarization (VP), an induced imbalance in the populations of a multi-valley electronic system, allows emission of second harmonic (SH) light even in centrosymmetric crystal…
