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…

Unveiling Excitonic Insulator Signatures in Ta $_{2}$ NiSe $_{5}$

Nour Maraytta, Peter Nagel, Fatemeh Ghorbani +10

The high-temperature phase of Ta $_{2}$ NiSe $_{5}$ , a near-zero-gap semiconductor ( $E_{G}$ = 0), is a promising candidate for an excitonic insulator. Given the dome-like…
