This study demonstrates that calcium doping in highly ordered lead scandium tantalate (PST) enables precise tuning of its phase transitions to induce both conventional and inverse electrocaloric effects, thereby expanding the material's effective cooling range from 263 K to 353 K for use in cascaded electrocaloric devices.
This paper introduces a novel experimental platform for high-pressure transport measurements in freestanding oxide films, which reveals a complex, dimensionality-dependent pressure-driven phase diagram in SrIrO3 featuring distinct semimetal-insulator and insulator-metal transitions in 3D films compared to the pressure-robust insulating state of 2D monolayers.
This paper proposes that transitions between zero-field-split states of paramagnetic impurities (such as Cr, Fe, and V) in sapphire generate magnetic absorption that contributes a loss tangent of – at 4.5 GHz, suggesting this mechanism is a significant limiting factor for the coherence times of superconducting qubits.
This study demonstrates that resonant above-bandgap optical excitation in the insulating antiferromagnet DyFeO3 induces a near-total collapse of the THz magnon gap by transiently reducing the exchange interaction by nearly 90%, thereby establishing a pathway for ultrafast, light-driven control of antiferromagnetic spin dynamics.
This paper introduces and benchmarks an efficient approximation technique that quantifies electron-phonon coupling for solid-state defects using only excited-state forces at the ground-state geometry, demonstrating that key optical properties can be accurately predicted with minimal atomic displacements while establishing the one-dimensional accepting-mode Huang-Rhys factor as a strict upper bound.
This paper introduces the ghost Gutzwiller variational embedding framework to bridge the gap between single-particle band theory and strong electronic correlations, enabling the efficient prediction of topological features in correlated materials and revealing novel phenomena such as topologically nontrivial Hubbard bands with distinct edge states.
This paper demonstrates that machine learning interatomic potentials, fine-tuned on routine atomic relaxation data from first-principles calculations, can efficiently and accurately predict electron-phonon coupling and optical lineshapes for defects in solids, overcoming the computational bottleneck of traditional methods while resolving fine spectral details like those of the T center in silicon.
By combining DFT+ with exact diagonalization of the Anderson impurity model to account for Ce–Ce valence fluctuations, this study successfully reproduces the experimental magnetic moment and uniaxial anisotropy of the CeCo ferromagnet, demonstrating the critical role of dynamical correlations in designing high-performance permanent magnets.
This study combines XMCD experiments with theoretical calculations to characterize the electronic and magnetic properties of light rare-earth cubic Laves compounds, revealing crystal field suppression of rare-earth moments, a finite magnetic moment on Ni, and a tunable mixed-valent ground state in Ce that can be controlled via composition.
This paper reports the spontaneous emergence of a stable, equilibrium gas of negative trions at the surface of the layered semiconductor Ta2NiS5, revealed by angle-resolved photoemission spectroscopy as a unique interaction-driven surface state stabilized by band bending and quasi-one-dimensional geometry.
