  text: Summary form only given. For a proper understanding of nonlinear optical experiments
    in semiconductors even the low-density limit Coulomb-induced many body correlations
    beyond the Hartree-Fock decoupling scheme need to be considered. In the coherent
    X(3) limit these correlations manifest themselves in the contributions of bound
    and unbound two-exciton states to the optical response. The understanding of nonlinear
    excitonic effects in the Stark effect of semiconductors including carrier-correlations
    is still of fundamental interest.

  text: 'Recent experiments by Roskos et al. in ultrashort optical pulse excitation
    of biased coupled quantum wells have shown remarkable generation of terahertz
    electromagnetic radiation. Two different effects were identified: (i) an oscillatory
    field of frequency corresponding to the separation between the coupled levels
    in the quantum-well pair (~ 1.5 THz); and (ii) an “instantaneous” electromagnetic
    field pulse that appears to follow the time evolution of the exciting laser pulse.
    The oscillatory field is understood to be caused by the coherent oscillation of
    optically created electrons from one well to the other.[1] The “instantaneous”
    part we believe is caused by a new mechanism proposed in Ref. 2. The essence of
    this “instantaneous” mechanism is that electron-hole pairs are created in a biased
    semiconductor with a net polarization. The density of these pairs follows the
    light field, as does the induced polarization, hence, generating an electromagnetic
    source that follows the light pulse. Such mechanisms have been discussed before
    for photon energies below the optical bandgap energy,[3] although they have so
    far been difficult to observe. In our work, we have generalized and extended such
    effects to photon energies above the handgap energy. In this paper we will discuss
    both of these mechanisms as well as the fourwave-mixing (FWM) signal,[4] and show
    how they can be understood within one unified formalism. We will also show that
    the calculations agree well with the experimental results.'

  text: "In the presence of a homogeneous electric field, \U0001D439→, each Bloch
    state in a crystal changes quasimomentum according to the so-called acceleration
    theorem Thus, in the absence of interband tunneling and scattering processes,
    each Bloch state moves at a constant velocity in k-space and executes a periodic
    motion in the reduced zone scheme by undergoing a Bragg reflection between each
    two traversals of the Brillouin zone."
