PySlice: Routine Vibrational Electron Energy Loss Spectroscopy Prediction with Universal Interatomic Potentials
Harrison A. Walker, Thomas W. Pfeifer, Paul M. Zeiger +3
Vibrational spectroscopy in the electron microscope can reveal phonon excitations with nanometer spatial resolution, yet routine prediction remains out of reach due to fragmented w…
Hydrogen bonding in water under extreme confinement
Xintong Xu, Matthias Kuehne, Harrison A. Walker +10
Fluids under extreme confinement exhibit unique structures and intermolecular bonding, distinct from their bulk analogs, driving innovative applications at the water-energy nexus.…
Topology-Driven Vibrations in a Chiral Polar Vortex Lattice
Eric R. Hoglund, Harrison A. Walker, Peter Meisenheimer +13
The ordering of magnetic or electric dipoles leading to real-space topological structures is at the forefront of materials research as their quantum mechanical nature often lends i…
Electrothermal manipulation of current-induced phase transitions in ferrimagnetic MnSiTe
Jiaqi Fang, Jiawei Hu, Xintian Chen +10
Phase transitions driven by external stimuli are central to condensed matter physics, providing critical insights into symmetry breaking and emergent phenomena. Recently, ferrimagn…
Ruddlesden-Popper chalcogenides push the limit of mechanical stiffness and glass-like thermal conductivity in single crystals
Md Shafkat Bin Hoque, Eric R. Hoglund, Boyang Zhao +20
Insulating materials featuring ultralow thermal conductivity for diverse applications also require robust mechanical properties. Conventional thinking, however, which correlates st…
