Pressure-tuning of electronic structure of CeTe3 probed by femtosecond collective mode spectroscopy
Chandra V. Kotyada, Priyanka Yogi, Amon P. Lanz +8
We use femtosecond optical spectroscopy to study the evolution of coherent order-parameter dynamics in the prototypical charge-density-wave (CDW) system CeTe3 under hydrostatic pre…
Ultrafast decoupling of quasiparticles and spin fluctuations in superconducting cuprates
Yuto Taniguchi, Ryo Kato, Tatsuya Amano +10
Understanding how quasiparticles are generated following a rapid quench of superconductivity in high-Tc cuprates is a key unresolved problem in nonequilibrium superconductivity. He…
Possible Eliashberg-type superconductivity enhancement effects in a two-band superconductor MgB2 driven by narrow-band THz pulses
Sergei Sobolev, Amon Lanz, Tao Dong +12
We study THz-driven condensate dynamics in epitaxial thin films of MgB, a prototype two-band superconductor (SC) with weak interband coupling. The temperature and excitation…
Control of the asymmetric band structure in Mn2Au by a ferromagnetic driver layer
Y. Lytvynenko, O. Fedchenko, S. V. Chernov +15
Hard X-ray angle-resolved photoemission spectroscopy reveals the momentum-resolved band structure in an epitaxial Mn2Au(001) film capped by a 2 nm thick ferromagnetic Permalloy lay…
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…
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…
