Transition-Metal-Oxygen Covalency Controls Ligand-Hole Stability in Li-Rich Cathode
Kuan H. Hsu, Eder G. Lomeli, Jaehoon Kim +9
Lithium-rich cathodes boast a large specific capacity due to the presence of excess lithium per transition metal. However, making use of that excess Li drives the cathodes to unusu…
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…
Biaxial Strain Control of Helimagnetism via Chemical Expansion in Thin Film SrFeO3
Jennifer Fowlie, Jiarui Li, Danilo Puggioni +15
We demonstrate control of helimagnetic order in biaxially strained SrFeO3 thin films using neutron diffraction and resonant soft x-ray scattering. SrFeO3, a negative charge-transfe…
Negative Charge Transfer: Ground State Precursor towards High Energy Batteries
Eder G. Lomeli, Qinghao Li, Kuan H. Hsu +22
Modern energy applications, especially electric vehicles, demand high energy batteries. However, despite decades of intensive efforts, the highest energy density and commercially v…
Direct Observation of the Lindhard Continuum using Resonant Inelastic X-ray Scattering
Eder G. Lomeli, Sarbajaya Kundu, Yi-De Chuang +12
Understanding the excitations of quantum materials is essential for unraveling how their microscopic constituents interact. Among these, particle-hole excitations form a particular…
Chiral Altermagnon in MnTe
Daniel Jost, Resham B. Regmi, Eder G. Lomeli +12
Altermagnetism has surfaced as a novel magnetic phase, bridging the properties of ferro- and anti-ferromagnetism. The momentum-dependent spin-splitting observed in these materials…
Orbital inversion and emergent lattice dynamics in infinite layer CaCoO
Daniel Jost, Eder G. Lomeli, Woo Jin Kim +10
The layered cobaltate CaCoO exhibits a unique herringbone-like structure. Serving as a potential prototype for a new class of complex lattice patterns, we study the properties…
Time-resolved X-ray Spectroscopy from the Atomic Orbital Ground State Up
Daniel Jost, Eder G. Lomeli, Ta Tang +6
X-ray spectroscopy has been a key method to determine ground and excited state properties of quantum materials with atomic specificity. Now, new x-ray facilities are opening the do…
Electronic structure of the alternating monolayer-trilayer phase of La3Ni2O7
Sebastien N. Abadi, Ke-Jun Xu, Eder G. Lomeli +12
Recent studies of LaNiO have identified a bilayer (2222) structure and an unexpected alternating monolayer-trilayer (1313) structure, both of which feature signatures o…
Electrolyte Coatings for High Adhesion Interfaces in Solid-state Batteries from First Principles
Brandi Ransom, Akash Ramdas, Eder Lomeli +5
We introduce an adhesion parameter that enables rapid screening for materials interfaces with high adhesion. This parameter is obtained by density functional theory calculations of…
Correlative image learning of chemo-mechanics in phase-transforming solids
Haitao D. Deng, Hongbo Zhao, Norman L. Jin +14
Constitutive laws underlie most physical processes in nature. However, learning such equations in heterogeneous solids (e.g., due to phase separation) is challenging. One such rela…
Correlative analysis of structure and chemistry of LixFePO4 platelets using 4D-STEM and X-ray ptychography
L. A. Hughes, Benjamin H. Savitzky, Haitao D. Deng +9
Lithium iron phosphate (LixFePO4), a cathode material used in rechargeable Li-ion batteries, phase separates upon de/lithiation under equilibrium. The interfacial structure and che…
