Discovery of Orbital Ordering in Bi2Sr2CaCu2O8+x
Shuqiu Wang, Niall Kennedy, Kazuhiro Fujita +5
The primordial ingredient of cuprate superconductivity is the CuO2 unit cell. Here, theoretical attention usually concentrates on the intra-atom Coulombic interactions dominating t…
Identification of a Nematic Pair Density Wave State in Bi2Sr2CaCu2O8+x
Weijiong Chen, Wangping Ren, Niall Kennedy +6
Electron-pair density wave (PDW) states are now an intense focus of research in the field of cuprate correlated superconductivity. PDWs exhibit periodically modulating superconduct…
On the Electron Pairing Mechanism of Copper-Oxide High Temperature Superconductivity
S. M. O'Mahony, Wangping Ren, Weijiong Chen +6
The elementary CuO2 plane sustaining cuprate high-temperature superconductivity occurs typically at the base of a periodic array of edge-sharing CuO5 pyramids. Virtual transitions…
Measurements of Nonequilibrium Interatomic Forces in Photoexcited Bismuth
Samuel W. Teitelbaum, Thomas C. Henighan, Hanzhe Liu +11
We determine experimentally the excited-state interatomic forces in photoexcited bismuth. The forces are obtained by a constrained least-squares fit of the excited-state dispersion…
Ultrafast relaxation of symmetry-breaking photo-induced atomic forces
Shane M. O'Mahony, Felipe Murphy-Armando, Éamonn D. Murray +3
We present a first-principles method for the calculation of the temperature-dependent relaxation of symmetry-breaking atomic driving forces in photoexcited systems. We calculate th…
Direct Measurement of Anharmonic Decay Channels of a Coherent Phonon
Samuel W. Teitelbaum, Tom Henighan, Yijing Huang +12
We observe anharmonic decay of the photoexcited coherent A1g phonon in bismuth to points in the Brillouin zone where conservation of momentum and energy are satisfied for three-pho…
