Systematic Studies of the Micro-Bunching Instability at Very Low Bunch Charges
Miriam Brosi, Johannes L. Steinmann, Edmund Blomley +14
At KARA, the KArlsruhe Research Accelerator of the KIT synchrotron, the so called short bunch operation mode allows the reduction of the bunch length down to a few picoseconds. The…
Giant exciton Fano resonance in quasi-one-dimensional TaNiSe
T. I. Larkin, A. N. Yaresko, D. Pröpper +8
We report the complex dielectric function of the quasi-one-dimensional chalcogenide TaNiSe, which exhibits a structural phase transition that has been attributed to exciton…
Fast Mapping of Terahertz Bursting Thresholds and Characteristics at Synchrotron Light Sources
Miriam Brosi, Johannes L. Steinmann, Edmund Blomley +12
Dedicated optics with extremely short electron bunches enable synchrotron light sources to generate intense coherent THz radiation. The high degree of spatial compression in this s…
Non-thermal response of YBCO thin films to picosecond THz pulses
P. Probst, A. Semenov, M. Ries +16
The photoresponse of YBa2Cu3O7-d thin film microbridges with thicknesses between 15 and 50 nm was studied in the optical and terahertz frequency range. The voltage transients in re…
Metal-insulator transition in the low-dimensional organic conductor (TMTSF)2FSO3 probed by infrared microspectroscopy
A. Pashkin, K. Thirunavukkuarasu, Y. -L. Mathis +2
We present measurements of the infrared response of the quasi-one-dimensional organic conductor (TMTSF)2$SO3 along (E||a) and perpendicular (E||b') to the stacking axis as a functi…
Pressure-driven orbital reorientation and change in Mott-Hubbard gap in YTiO3
I. Loa, X. Wang, K. Syassen +4
We investigate the crystal structure of YTiO3 at high pressures up to 30 GPa by synchrotron x-ray powder diffraction (T = 295 K). The variation of the Ti--O bond lengths with press…
Josephson plasma resonance and phonon anomalies in trilayer Bi_2Sr_2Ca_2Cu_3O_10 superconductor
A. V Boris, D. Munzar, N. N. Kovaleva +8
The far-infrared (FIR) c axis conductivity of a Bi2223 crystal has been measured by ellipsometry. Below T a strong absorption band develops near 500 cm , corresponding t…
