Observation of correlated plasmons in low-valence nickelates
Y. Shen, W. He, J. Sears +13
The discovery of nickelate superconductors has opened a new arena for studying the behavior of correlated electron liquids that give rise to unconventional superconductivity. While…
Disentangling multi-spin dynamic correlations in the Heisenberg spin- chain
V. K . Bhartiya, U. Kumar, T. Kim +8
Higher-order correlations are essential for understanding exotic phases and uncovering universal aspects of quantum dynamics. While inelastic neutron scattering provides well-estab…
Interlayer Five-Spin Polaron in Superconducting Bilayer Nickelates
Jiarui Li, Christopher T. Parzyck, Eder G. Lomeli +19
The discovery of high- superconductivity in Ruddlesden-Popper nickelates has sparked substantial effort towards understanding unconventional electronic states beyond a traditi…
Magnetic order, magnons, and crystal fields in van der Waals CeSiI
Wolfgang Simeth, Connor A. Occhialini, Michael E. Ziebel +12
We report neutron, X-ray absorption, and resonant X-ray spectroscopy of magnetic excitations in the new heavy-fermion van-der-Waals superconductor CeSiI. We determined effective Ha…
Excitations across the equilibrium and photoinduced `hidden' states of magnetoresistive manganites
Shiyu Fan, Feng Jin, Taehun Kim +16
"Hidden" phases, generated using ultrafast laser pulses (few hundred femtoseconds), with properties distinct from thermodynamic equilibrium, are appealing for technologies because…
Superconducting phase diagram of multi-layer square-planar nickelates
Grace A. Pan, Dan Ferenc Segedin, Sophia F. R. TenHuisen +21
The discovery of superconductivity in square-planar nickelates has offered a rich materials platform to explore the origins of cuprate-like superconductivity. Experimental investig…
