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…
