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…
Hierarchical quasiparticle dynamics in antiferromagnets revealed by time- and momentum-resolved X-ray scattering
Arnau Romaguera, Elizabeth Skoropata, Yun Yen +18
Energy flows among coupled subsystems are essential for ultrafast dynamics and high-speed technologies. In magnetic materials, spin fluctuations -- magnons -- mediate these flows i…
Ultrafast Decoherence of Charge Density Waves in KMoO
Rafael T. Winkler, Larissa Boie, Yunpei Deng +20
Recent works have suggested that transient suppression of a charge density wave (CDW) by an ultra-short excitation can lead to an inversion of the CDW phase. We experimentally inve…
Magnetic excitations in NdNiO Ruddlesden-Popper nickelates observed via resonant inelastic x-ray scattering
Sophia F. R. TenHuisen, Grace A. Pan, Qi Song +16
Magnetic interactions are thought to play a key role in the properties of many unconventional superconductors, including cuprates, iron pnictides, and square-planar nickelates. Sup…
Chiral phonons in polar LiNbO3
Hiroki Ueda, Abhishek Nag, Carl P. Romao +3
Quasiparticles describe collective excitations in many-body systems, and their symmetry classification is of fundamental importance because they govern physical processes on variou…
Ultrafast selective mid-infrared sublattice manipulation in the ferrimagnet
Davide Soranzio, Matteo Savoini, Fabian Graf +6
is a ferrimagnet with two oppositely ordered spin sublattices (Fe and Cr), connected via superexchange interaction, giving a non-zero net magnetic moment. We show, usin…
