Performance Classification and Remaining Useful Life Prediction of Lithium Batteries Using Machine Learning and Early Cycle Electrochemical Impedance Spectroscopy Measurements
Christian Parsons, Adil Amin, Prasenjit Guptasarma
We presents an approach for early cycle classification of lithium-ion batteries into high and low-performing categories, coupled with the prediction of their remaining useful life…
Improved interfacial resistance and crystal-structure stability in a low-cobalt P2-type sodium-ion battery cathode material
William Rexhausen, Christian Parsons, Uma Garg +2
We describe Na0.67Mn0.625Fe0.25Co0.125O2 (NMFCO), a P2-type sodium-ion battery cathode. Our composition, with significantly less Co than in an earlier study, shows discharge capaci…
Charge Density Wave Order in Superconducting Topological Insulator Nbx-Bi2Se3
Yanan Li, Christian Parsons, Sanath Ramakrishna +6
Spontaneously broken symmetry in the ground state of Bi-based topological materials can lead to promising Topological superconductors, such as Cu-Bi2Se3, Sr-Bi2Se3 and Nb-Bi2Se3. I…
Anomalous 140 K electronic transition in BiSe: Possible charge order in a defect-engineered system
Yanan Li, Christian Parsons, Sanath Kumar Ramakrishna +4
We report an anomalous electronic transition at 140~K in high-quality BiSe, where charge order emerges in a defect-tuned system. Native defects (Se vacancies and Bi interca…
Three-photon-annihilation contributions to positronium energies at order
Gregory S. Adkins, Minji Kim, Christian Parsons +1
Positronium spectroscopy (n=1 hyperfine splitting, n=2 fine structure, and the 1S-2S interval) has reached a precision of order 1 MHz. Vigorous ongoing efforts to improve the exper…
Positronium energy levels at order : vacuum polarization corrections in the two-photon-annihilation channel
Gregory S. Adkins, Christian Parsons, M. D. Salinger +1
We have calculated all contributions to the energy levels of parapositronium at order coming from vacuum polarization corrections to processes involving virtual annihilatio…
Positronium energy levels at order : light-by-light scattering in the two-photon-annihilation channel
Gregory S. Adkins, Christian Parsons, M. D. Salinger +2
Recent and ongoing experimental work on the positronium spectrum motivates new efforts to calculate positronium energy levels at the level of three loop corrections. We have obtain…
