  abstract     = {{The vibrational properties of the LiNbO3 (0001) surfaces have been investigated both from first principles and with Raman spectroscopy measurements. Firstly, the phonon modes of bulk and of the (0001) surface are calculated by means of the density functional theory. Our calculations reveal the existence of localised vibrational modes both at the positive and at the negative surface. The surface vibrations are found at energies above and within the bulk bands. Phonon modes localised at the positive and at the negative surface differ substantially. In a second step, the Raman spectra of LiNbO3 bulk and of the two surfaces have been measured. Raman spectroscopy is shown to be sensitive to differences between bulk and surface and between positive and negative surface. The calculated and measured frequencies are in agreement within the error of the method.}},

  abstract     = {{We experimentally and theoretically investigate injection currents generated by femtosecond single-color circularly-polarized laser pulses in (110)-oriented GaAs quantum wells. The current measurements are performed by detecting the emitted Terahertz radiation at room temperature. The microscopic theory is based on a 14 x 14 k • p band-structure calculation in combination with the multi-subband semiconductor Bloch equations. For symmetric GaAs quantum wells grown in (110) direction, an oscillatory dependence of the injection currents on the exciting photon energy is obtained. The results of the microscopic theory are in good agreement with the measurements. }},

  abstract     = {{We demonstrate by spin quantum beat spectroscopy that in undoped symmetric (110)-oriented GaAs/AlGaAs
single quantum wells, even a symmetric spatial envelope wave function gives rise to an asymmetric in-plane
electron Land´e g-factor. The anisotropy is neither a direct consequence of the asymmetric in-plane Dresselhaus
splitting nor a direct consequence of the asymmetric Zeeman splitting of the hole bands, but rather it is a pure
higher-order effect that exists as well for diamond-type lattices. The measurements for various well widths are
very well described within 14 × 14 band k·p theory and illustrate that the electron spin is an excellent meter
variable for mapping out the internal—otherwise hidden—symmetries in two-dimensional systems. Fourth-order
perturbation theory yields an analytical expression for the strength of the g-factor anisotropy, providing a
qualitative understanding of the observed effects.}},

This paper introduces the technique of algorithmic differentiation, a method to compute derivatives of arbitrary order within working precision. This derivative information will be combined with a calculus-based optimization algorithm to optimize a non-trivially shaped laser pulse which coherently steers the electron dynamics in a semiconductor quantum wire. Numerical results illustrating the cost for the derivative computation and the optimization process are presented and discussed.}},
