Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper proposes that the FLASH effect in cancer radiation therapy, which spares normal tissues while killing tumors, arises from structural differences between ordered normal and disordered tumor tissues that lead to the formation of electron-hole liquids in normal tissues, thereby suppressing harmful free radical generation.
This study demonstrates that applying mechanical pressure to epitaxial BiFeO3 thin films suppresses ferroelastic domain competition and significantly lowers the energy barrier for polarization reversal, enabling spontaneous switching at zero voltage and establishing mechanical stress as a powerful thermodynamic control parameter for manipulating multiferroic order.
This study utilizes first-principles calculations to demonstrate that hydrostatic pressure and biaxial compressive strain both suppress octahedral tilts in the hybrid bilayer-trilayer nickelate LaNiO to stabilize a tetragonal structure, yet they induce distinct electronic behaviors by causing the trilayer band to cross the Fermi level under pressure while keeping it below the Fermi level under strain.
Using fixed-node diffusion quantum Monte Carlo, this study resolves the debate over the magnetic ground state of bulk rutile RuO by demonstrating that it is nonmagnetic in its pristine structure but can be stabilized into an antiferromagnetic state under 3% compressive strain, thereby reconciling conflicting experimental reports.
This study investigates the high-pressure behavior of honeycomb layered magnetoelectrics Mn4Nb2O9 and Mn4Ta2O9 using Raman spectroscopy, synchrotron X-ray diffraction, and DFT calculations, revealing that pressure induces multiple isostructural transitions driven by local symmetry breaking and anisotropic lattice compression, ultimately leading to a long-range P-3c1 to P2/c structural phase transition with distinct pressure thresholds and mechanisms influenced by the differing spin-orbit coupling and orbital hybridization of Nb and Ta cations.
This study utilizes diffusion Monte Carlo to benchmark and optimize the Hubbard parameter in DFT+ calculations for strained monolayer MnBiTe, revealing that a strain-dependent following a quadratic form is essential for accurately capturing the material's magnetic properties.
This study reveals that the poor n-type conductivity in Al-rich AlGaN alloys, which hinders far-UVC LED performance, is primarily caused by Si dopants forming compensating negative-U DX centers on minority Ga sites and carbon impurities, findings that underscore the necessity of explicit alloy modeling and proper band gap temperature treatment to accurately predict carrier concentrations.
This study demonstrates that engineering nitrogen termination on diamond surfaces significantly enhances Cu/diamond interfacial thermal conductance by 21% through surficial mass modification and bonding regulation that selectively modulates high-frequency phonon transport, offering a promising non-metallic strategy to overcome interfacial limitations in Cu-diamond composites.
This study employs density functional theory to comprehensively investigate the pressure-dependent structural, electronic, mechanical, thermophysical, vibrational, and optical properties of the intermetallic Kagome compound ZrRe2, revealing its stability up to 25 GPa, the pressure-induced vanishing of topological features, a potential charge density wave phase, and a decrease in superconducting transition temperature due to weakened electron-phonon coupling.
This paper proposes a gauge-theoretic framework for plasticity derived from spontaneous spacetime symmetry breaking, demonstrating that defect kinematics are fundamentally determined by non-dissipative symmetry principles and conservation laws, with dissipative flow emerging as a controlled deformation of this conservative structure.
