Orbital Ordering in the Charge Density Wave Phases of BaNi $_{2}$ (As $_{1 - x}$ P $_{x}$ ) $_{2}$

Tom Lacmann, Robert Eder, Igor Vinograd +8

We use resonant X-ray scattering at the nickel L $_{2, 3}$ edges to investigate the interplay between orbital degrees of freedom and charge density waves (CDW) in the superconductor…

Strain-induced structural change and nearly-commensurate diffuse scattering in the model high-temperature superconductor HgBa $_{2}$ CuO $_{4 + I^´}$

Mai Ye, Wenshan Hong, Tom Lacmann +9

We investigate the strain response of underdoped HgBa $_{2}$ CuO $_{4 + I^´}$ (Hg1201), by synchrotron X-ray diffraction and corresponding simulations of thermal diffuse scattering. The co…

Charge density waves and soft phonon evolution in the superconductor BaNi $_{2}$ (As $_{1 - x}$ P $_{x}$ ) $_{2}$

Tom Lacmann, Sofia-Michaela Souliou, Fabian Henssler +8

The superconductor BaNi $_{2}$ As $_{2}$ exhibits a soft-phonon-driven, incommensurate charge density wave (I-CDW) which is accompanied by a small orthorhombic structural phase transition…

Strange metal from spin fluctuations in a cuprate superconductor

D. J. Campbell, M. Frachet, V. Oliviero +7

Strange metals challenge our understanding of charge transport in metals. Here, we investigate how the strange metal phase of La $_{2 - x}$ Sr $_{x}$ CuO $_{4}$ is impacted by a field-induced…

Chemical pressure tuning of competing orders in $Ba_{1 - x} Ca_{x} Ni_{2} As_{2}$

F. Henssler, K. Willa, M. Frachet +5

$Ba Ni_{2} As_{2}$ , a structural-analogue to the iron-based parent compound $Ba Fe_{2} As_{2}$ , offers a unique platform to study…
