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.
SrCo2P2 undergoes a pressure-induced collapsed-tetragonal (cT) phase transition transition-driven by interlayer pnictogen bonding resulting in a remarkable near room temperature ferromagnetic ordering (TC up to 260 K) in the cT phase.
Numerical simulations demonstrate a cavity-free metasurface laser capable of controllable, purely circularly polarized output via direct lasing from chiral resonant modes of plasmonic meta-atoms strongly coupled to quantum gain.
The topography of Fermi arcs in trigonal PtBi2 (ti-PtBi2) was revealed. Unlike in other topological materials, the arc in t-PtBi2 is well separated from other bands, which allows precise determination of its end-points, dispersion, and Fermi crossing of the band that forms it.
