Temperature-driven Topological Phase Transition and Intermediate Dirac Semimetal Phase in ZrTe
B. Xu, L. X. Zhao, P. Marsik +6
We present an infrared spectroscopy study of ZrTe, which confirms a recent theoretical proposal that this material exhibits a temperature-driven topological quantum phase trans…
Scaling of the Fano effect of the in-plane Fe-As phonon and the superconducting critical temperature in BaKFeAs
B. Xu, E. Cappelluti, L. Benfatto +11
By means of infrared spectroscopy we determine the temperature-doping phase diagram of the Fano effect for the in-plane Fe-As stretching mode in BaKFeAs.…
Terahertz-Driven Phonon Upconversion in SrTiO3
Michael Kozina, Michael Fechner, Premysl Marsik +8
Direct manipulation of the atomic lattice using intense long-wavelength laser pulses has become a viable approach to create new states of matter in complex materials. Conventionall…
Optical study of Dirac fermions and related phonon anomalies in antiferromagnetic compound CaFeAsF
B. Xu, H. Xiao, B. Gao +8
We performed optical studies on CaFeAsF single crystals, a parent compound of the 1111-type iron-based superconductors that undergoes a structural phase transition from tetragonal…
