Quantum Sensing for Spatial Spin Noise Mapping via Nitrogen-Vacancy Magnetic Quenching in Diamond

Ashley J. Tyler, Thomas D. Bateman-Price, Bradley T. Flinn +4

Detecting and mapping spin noise can reveal spatial variations in surface defect states, catalytic residues, free radicals, and spintronic materials. However, bulk measurements ave…

Polar Topologies in a Ferroelastic Metal Membrane

Rahil Haria, Noah Schnitzer, T. Ben Britton +10

Polar metals, materials in which electric polarisation and metallicity coexist, are exceptionally rare because itinerant electrons screen long-range dipoles and favour centrosymmet…

Revisiting intrinsic spin defects in hexagonal boron nitride with r2SCAN

Petros-Panagis Filippatos, Tom J. P. Irons, Katherine Inzani

Hexagonal boron nitride (hBN) is a wide band gap, van der Waals material that is highly promising for solid-state quantum technologies as a host of optically addressable, paramagne…

How Semilocal Are Semilocal Density Functional Approximations? -Tackling Self-Interaction Error in One-Electron Systems

Akilan Ramasamy, Lin Hou, Jorge Vega Bazantes +4

Self-interaction error (SIE), arising from the imperfect cancellation of the spurious classical Coulomb interaction between an electron and itself, is a persistent challenge in mod…

Coupling-Constant Averaged Exchange-Correlation Hole for He, Li, Be, N, Ne Atoms from CCSD

Lin Hou, Tom J. P. Irons, Yanyong Wang +3

Accurate approximation of the exchange-correlation (XC) energy in density functional theory (DFT) calculations is essential for reliably modelling electronic systems. Many such app…

Magnetic Optical Rotation from Real-Time Simulations in Finite Magnetic Fields

Benedicte Sverdrup Ofstad, Meilani Wibowo-Teale, Håkon Emil Kristiansen +8

We present a numerical approach to magnetic optical rotation based on real-time time-dependent electronic-structure theory. Not relying on perturbation expansions in the magnetic-f…

Capturing the electron-electron cusp with the coupling-constant averaged exchange-correlation hole: A case study for Hooke's atoms

Lin Hou, Tom J. P. Irons, Yanyong Wang +3

In density functional theory the exchange-correlation (XC) energy functional can be defined exactly through the coupling-constant () averaged XC hole $\bar{n}_\text{xc}(\mathbf{…

Exact constraints and appropriate norms in machine learned exchange-correlation functionals

Kanun Pokharel, James W. Furness, Yi Yao +4

Machine learning techniques have received growing attention as an alternative strategy for developing general-purpose density functional approximations, augmenting the historically…

Robust All-Electron Optimization in Orbital-Free Density Functional Theory Using the Trust Region Image Method

Matthew S. Ryley, Michael Withnall, Tom J. P. Irons +2

We present a Gaussian-basis implementation of orbital-free density-functional theory (OF-DFT) in which the trust-region image method (TRIM) is used for optimization. This second-or…

Interpolated energy densities, correlation indicators and lower bounds from approximations to the strong coupling limit of DFT

Stefan Vuckovic, Lucas O. Wagner, Andrew M. Teale +1

We investigate the construction of approximated exchange-correlation functionals by interpolating locally along the adiabatic connection between the weak- and the strong-coupling r…

Exchange-correlation functionals via local interpolation along the adiabatic connection

Stefan Vuckovic, Tom Irons, Andreas Savin +2

The construction of density-functional approximations is explored by modeling the adiabatic connection em locally, using energy densities defined in terms of the electrostatic pote…
