Scientists at Ames National Laboratory, in collaboration with Indranil Das’s group at the Saha Institute of Nuclear Physics (India), have found a surprising electronic feature in transitional metal-based compounds that could pave the way for a new class of spintronic materials for computing and memory technologies.
CMI education and outreach ranges from youth to adult, with an emphasis on workforce development. Beginning in 2024, this includes a CMI Internship Program.
Max Delferro, the deputy director of iCOUP, will be presenting in an upcoming Periodic Table Talk, sponsored by ACSDIC.
Epitaxial graphene patterning platform is developed by using the scanning tunneling microscope (STM). A local electric field controls the covalent C-Si bonds at the buried graphene – SiC interface, allowing their reversible breaking and formation.
Fluence-dependent photocurrents enable controlled transitions within (TaSe4)2I, shifting it sequentially from a polaronic state to a charge density wave (CDW) state, and ultimately to a concealed Weyl phase.
This research presents a viable candidate approach to perform ground state calculations on large-size systems beyond 100 qubits to achieve quantum utility before fault tolerance.
Accurate simulations of Green’s functions and nonlinear susceptibilities for electron and spin systems are achieved with highly compressed circuits.
Enforcing Hund’s rules in density functional theory (DFT) calculations is necessary for reliable modeling of rare-earth magnetic anisotropy (MA). Scientists at Ames National Laboratory and George Mason University collaborated to identify and address the most fundamental challenge in accurately modeling rare-earth MA within DFT.
The phonon dynamics of methylammonium lead iodide are explored with time-resolved terahertz spectroscopy and first-principles molecular dynamics simulations, revealing a bidirectional entropy transfer mechanism that may inform the design of perovskite active layers in solar cells and optoelectronic devices.
