Fermi-liquid-like phase driven by next-nearest-neighbor couplings in a lightly doped kagome-lattice - model
Xu-Yan Jia, Fan Yang, D. N. Sheng +1
Due to the interplay between charge fluctuation and geometry frustration, the doped kagome-lattice Mott insulator is a fascinating platform to realize exotic quantum states. Throug…
Crystal-Field--Driven Magnetoelectricity in the Triangular Quantum Magnet CeMgAlO
Sonu Kumar, Gaël Bastien, Gaël Bastien +10
We report dielectric and magnetoelectric studies of single-crystalline \ce{CeMgAl11O19}, a Kramers triangular magnet embedded in a polarizable hexaaluminate lattice. In zero magnet…
Theory of Momentum-Resolved Electron Energy-Loss Spectra of Coupled Phonon and Magnon Excitations
José Ãngel Castellanos-Reyes, Ivan P. Miranda, Paul M. Zeiger +2
We develop a theory of momentum-resolved electron energy-loss spectra in the scanning transmission microscope (STEM-EELS) that captures the effects of coupled phonon and magnon exc…
Backscattering Study of Electrons from 0.1 to 3.4 MeV
M. Kanafani, X. Fléchard, O. Naviliat-Cuncic +10
Benchmarking simulation codes for electron transport and scattering in matter is a crucial step for estimating uncertainties in many applications. However, experimental data for el…
Effects of Interactions and Defect Motion on Ramp Reversal Memory in Locally Phase Separated Materials
Y. Sun, M. Alzate Banguero, P. Salev +4
The ramp-reversal memory (RRM) effect in metal-insulator transition metal oxides (TMOs), a non-volatile resistance change induced by repeated temperature cycling, has attracted con…
The Local Distance Network: a community consensus report on the measurement of the Hubble constant at 1% precision
H0DN Collaboration, Stefano Casertano, Gagandeep Anand +35
The direct, empirical determination of the local value of the Hubble constant (H0) has markedly advanced thanks to improved instrumentation, measurement techniques, and distance es…
