Photoinduced melting of antiferromagnetic order in La(0.5)Sr(1.5)MnO4 measured using ultrafast resonant soft x-ray diffraction.

We used ultrafast resonant soft x-ray diffraction to probe the picosecond dynamics of spin and orbital order in La(0.5)Sr(1.5)MnO(4) after photoexcitation with a femtosecond pulse of 1.

Single-shot detection and direct control of carrier phase drift of midinfrared pulses.

We introduce a scheme for single-shot detection and correction of the carrier-envelope phase (CEP) drift of femtosecond pulses at mid-IR wavelengths. Difference frequency mixing between the mid-IR field and a near-IR gate pulse generates a near-IR frequency-shifted pulse, which is then spectrally interfered with a replica of the gate pulse. The spectral interference pattern contains shot-to-shot information of the CEP of the mid-IR field, and it can be used for simultaneous correction of its slow drifts.

Coherent structural dynamics and electronic correlations during an ultrafast insulator-to-metal phase transition in VO2.

We directly trace the multi-THz conductivity of VO2 during an insulator-metal transition triggered by a 12-fs light pulse. The femtosecond dynamics of lattice and electronic degrees of freedom are spectrally discriminated. A coherent wave packet motion of V-V dimers at 6 THz modulates the lattice polarizability for approximately 1 ps.

[About the availability of computers in the general stomatologic practice].

A software-packet for the medical documentation in the general stomatologic practice is represented. The programme allows among others the print of findings, the therapeutic plan, the documentation of progress, the x-ray demand as well as the performance-proof. By that way the course of consultations, the mass-examinations and the valuation is effective possible after a short phase of adaption.
