Pressure Control of Nonferroelastic Ferroelectric Domains in ErMnO<inf>3</inf>
(Journal article; Peer reviewed, 2023)Mechanical pressure controls the structural, electric, and magnetic order in solid-state systems, allowing tailoring of their physical properties. A well-established example is ferroelastic ferroelectrics, where the coupling ... -
Andreev reflection in altermagnets
(Journal article; Peer reviewed, 2023)Recent works have predicted materials featuring bands with a large spin-splitting distinct from ferromagnetic and relativistically spin-orbit-coupled systems. Materials displaying this property are known as altermagnets ... -
Transient dynamics and quantum phase diagram for the square lattice Rashba-Hubbard model at arbitrary hole doping
(Peer reviewed; Journal article, 2023)Adding a Rashba term to the Hubbard Hamiltonian produces a model which can be used to learn how spin-orbit interactions impact correlated electrons on a lattice. Previous works have studied such a model using a variety of ... -
Spin pumping from a ferromagnetic insulator to an unconventional superconductor with interfacial Andreev bound states
(Journal article; Peer reviewed, 2023)Spin pumping from a ferromagnetic insulator into a high-Tc superconductor with a d-wave superconducting order parameter has recently been experimentally observed. Such unconventional superconducting order is known to ... -
Moiré fringes in conductive atomic force microscopy
(Journal article; Peer reviewed, 2023)Moiré physics plays an important role in characterization of functional materials and engineering of physical properties in general, ranging from strain-driven transport phenomena to superconductivity. Here, we report on ... -
Effect of scandium on grain refinement mechanism and mechanical properties of Al–7Si–0.6 Mg alloy at different cooling rates
(Peer reviewed; Journal article, 2023)The effects of scandium (Sc) additions on the solidification microstructure and mechanical properties of Al–7Si–0.6Mg-0.25Ti alloy at different cooling rates have been systematically studied by thermal analysis and detailed ... -
Effect of Microstructure on the Precipitation of β-Mg2Si during Cooling after Homogenisation of Al-Mg-Si Alloys
(Peer reviewed; Journal article, 2024)For Al-Mg-Si alloys, cooling after homogenisation is a crucial step because the precipitation of the equilibrium β-Mg2Si phase determines the processing capabilities in subsequent steps, as well as the subsequent precipitation ... -
Equation-of-motion coupled-cluster method with double electron-attaching operators: Theory, implementation, and benchmarks
(Journal article, 2021)We report a production-level implementation of the equation-of-motion (EOM) coupled-cluster (CC) method with double electron-attaching (DEA) EOM operators of 2p and 3p1h types, EOM-DEA-CCSD. This ansatz, suitable for ... -
Effect of the Ion, Solvent, and Thermal Interaction Coefficients on Battery Voltage
(Peer reviewed; Journal article, 2024)In order to increase the adoption of batteries for sustainable transport and energy storage, improved charging and discharging capabilities of lithium-ion batteries are necessary. To achieve this, accurate data that describe ... -
Molecular quantification of parasitic sea louse larvae depends on species and life stage
(Peer reviewed; Journal article, 2023)Sea lice cause substantial economic and environmental harm to Norway's aquacul-ture industry and wild salmonid populations. Rapid, accurate quantification of lice larval densities in coastal waters remains the greatest ... -
Multilevel CC2 and CCSD in Reduced Orbital Spaces: Electronic Excitations in Large Molecular Systems
(Peer reviewed; Journal article, 2021)We present efficient implementations of the multilevel CC2 (MLCC2) and multilevel CCSD (MLCCSD) models. As the system size increases, MLCC2 and MLCCSD exhibit the scaling of the lower-level coupled cluster model. To treat ... -
Quasiclassical theory for antiferromagnetic metals
(Peer reviewed; Journal article, 2023)Unlike ferromagnetism, antiferromagnetism cannot readily be included in the quasiclassical Keldysh theory because of the rapid spatial variation in the directions of of the magnetic moments. The quasiclassical framework ... -
Superconducting Proximity Effect and Long-Ranged Triplets in Dirty Metallic Antiferromagnets
(Journal article; Peer reviewed, 2023)Antiferromagnets have no net spin splitting on the scale of the superconducting coherence length. Despite this, antiferromagnets have been observed to suppress superconductivity in a similar way as ferromagnets, a phenomenon ... -
