Ultrafast gap dynamics upon photodoping the Mott-insulating phase of a two-dimensional organic charge-transfer salt
Konstantin Warawa, Yassine Agarmani, Harald Schubert +4
We investigate experimentally the ultrafast changes in the spectral response of the Mott insulator -(BEDT-TTF)Cu[N(CN)]Cl (-Cl) upon photodoping with intense excitati…
Strong coupling of plasmonic bright and dark modes with two eigenmodes of a photonic crystal cavity
Fanqi Meng, Lei Cao, Aristeidis Karalis +3
Dark modes represent a class of forbidden transitions or transitions with weak dipole moments between energy states. Due to their low transition probability, it is difficult to rea…
600-GHz Fourier Imaging Based on Heterodyne Detection at the 2nd Sub-harmonic
Hui Yuan, Alvydas Lisauskas, Mark D. Thomson +1
Fourier imaging is an indirect imaging method which records the diffraction pattern of the object scene coherently in the focal plane of the imaging system and reconstructs the ima…
Combined investigation of collective amplitude and phase modes in a quasi-one-dimensional charge-density-wave system over a wide spectral range
Konstantin Warawa, Nicolas Christophel, Sergei Sobolev +3
We investigate experimentally both the amplitude and phase channels of the collective modes in the quasi-1D charge-density-wave (CDW) system, K0.3MoO3, by combining (i) optical imp…
Higher-harmonic generation in boron-doped silicon from band carriers and bound-dopant photoionization
Fanqi Meng, Frederik Walla, Sergey Kovalev +10
We investigate ultrafast harmonic generation (HG) in Si:B, driven by intense pump pulses with fields reaching ~100 kV/cm and a carrier frequency of 300 GHz, at 4 K and 300 K, both…
Collective modes in the charge-density wave state of KMoO: The role of long-range Coulomb interactions revisited
Max O. Hansen, Yash Palan, Viktor Hahn +7
We re-examine the effect of long-range Coulomb interactions on the collective amplitude and phase modes in the incommensurate charge-density-wave ground state of quasi-one-dimensio…
Colossal magnetoresistance in EuZnP and its electronic and magnetic structure
Sarah Krebber, Marvin Kopp, Charu Garg +15
We investigate single crystals of the trigonal antiferromagnet EuZnP () by means of electrical transport, magnetization measurements, X-ray magnetic scatte…
