Optical control of vibrational coherence triggered by an ultrafast phase transition
M. J. Neugebauer, T. Huber, M. Savoini +13
Femtosecond time-resolved x-ray diffraction is employed to study the dynamics of the periodic lattice distortion (PLD) associated with the charge-density-wave (CDW) in K0.3MoO3. Us…
Dynamics of the photoinduced insulator-to-metal transition in a nickelate film
Vincent Esposito, Laurenz Rettig, Elisabeth M. Bothschafter +24
The control of materials properties with light is a promising approach towards the realization of faster and smaller electronic devices. With phases that can be controlled via stra…
Disentangling charge and structural contributions during coherent atomic motions studied by ultrafast resonant x-ray diffraction
L. Rettig, A. Caviezel, S. O. Mariager +20
We report on the ultrafast dynamics of charge order and structural response during the photoinduced suppression of charge and orbital order in a mixed-valence manganite. Employing…
Ultrafast relaxation dynamics of the antiferrodistortive phase in Ca doped SrTiO3
M. Porer, M. Fechner, E. Bothschafter +19
The ultrafast dynamics of the octahedral rotation in Ca:SrTiO3 is studied by time resolved x-ray diffraction after photo excitation over the band gap. By monitoring the diffraction…
Watching the birth of a charge density wave order: diffraction study on nanometer-and picosecond-scales
C. Laulhé, T. Huber, G. Lantz +18
Femtosecond time-resolved X-ray diffraction is used to study a photo-induced phase transition between two charge density wave (CDW) states in 1T-TaS, namely the nearly commensu…
Towards carbon nanotube growth into superconducting microwave resonator geometries
S. Blien, K. J. G. Götz, P. L. Stiller +4
The in-place growth of suspended carbon nanotubes facilitates the observation of both unperturbed electronic transport spectra and high-Q vibrational modes. For complex structures…
Ultrafast x-ray diffraction of a ferroelectric soft mode driven by broadband terahertz pulses
S. Grübel, J. A. Johnson, P. Beaud +14
Intense, few-cycle pulses in the terahertz frequency range have strong potential for schemes of control over vibrational modes in solid-state materials in the electronic ground-sta…
Co-sputtered MoRe thin films for carbon nanotube growth-compatible superconducting coplanar resonators
K. J. G. Götz, S. Blien, P. L. Stiller +7
Molybdenum rhenium alloy thin films can exhibit superconductivity up to critical temperatures of . At the same time, the films are highly stable in the high-tempe…
Coherent Acoustic Perturbation of Second-Harmonic-Generation in NiO
L. Huber, A. Ferrer, T. Kubacka +14
We investigate the structural and magnetic origins of the unusual ultrafast second-harmonicgeneration (SHG) response of femtosecond-laser-excited nickel oxide (NiO) previously attr…
Structural and Magnetic Dynamics in the Magnetic Shape Memory Alloy NiMnGa
S. O. Mariager, C. Dornes, J. A. Johnson +11
Magnetic shape memory Heusler alloys are multiferroics stabilized by the correlations between electronic, magnetic and structural order. To study these correlations we use time res…
