This paper demonstrates that a low in-plane magnetic field can reversibly switch between degenerate antiferromagnetic domains in the fully compensated material CeNiAsO, inducing a giant and nonvolatile resistivity anisotropy of approximately 35% across multiple magnetic phases.
This study utilizes a tight-binding model to demonstrate that strain-induced deformation in two-dimensional hexagonal lattices enables precise control over anisotropic optical properties and electronic transport through saddle-point filtering effects and van Hove singularities, thereby paving the way for strain-programmable optoelectronic devices.
This paper presents a theoretical framework demonstrating that altermagnet-superconductor heterostructures, particularly when augmented with Rashba spin-orbit coupling, serve as a versatile platform for inducing odd-parity triplet pairing and engineering both weak and strong topological superconducting phases with edge-localized modes.
By applying an in-plane magnetic field to a magnetic topological sandwich structure, researchers successfully realized a parity anomalous semimetal phase characterized by a single unpaired gapless Dirac cone and a distinctive two-stage conductivity evolution that stabilizes half-integer quantized Hall conductivity against localization.
This paper investigates how Coulomb interactions between electrons in -decaying impurities and their solid-state environment affect the energy resolution and visibility required for detecting the cosmic neutrino background, analyzing scenarios ranging from completely suppressed hybridization via dielectric spacers to cases where hybridization is treated perturbatively.
This paper presents a Wigner Transport Equation-based framework to model non-diffusive thermal transport driven by both phonon populations and coherences, predicting significant size-dependent thermal conductivity deviations in low-conductivity materials like CsPbBr and LaZrO at experimentally accessible length scales.
This paper characterizes the performance of Singlet-only always-on gapless exchange (SAGE) spin qubits under charge noise, demonstrating that realistic pulse sequences can significantly extend single-qubit coherence times and mitigate errors in two-qubit gates despite the increased sensitivity caused by always-on exchange couplings.
This paper demonstrates the simulation of altermagnets in the newly released micromagnetic package mumax+ by introducing a dedicated magnet class that successfully reproduces analytical domain wall profiles, anisotropic magnon dispersion, and spin-transfer-torque-driven skyrmion dynamics, leveraging its object-oriented design to accurately handle multi-sublattice magnetostatic fields.
This review provides a comprehensive overview of the droplet etching epitaxy technique for growing high-quality GaAs quantum dots in molecular beam epitaxy, systematically covering the three main growth phases, relating experimental results to crystal growth theories, and discussing photoluminescence properties and extensions to other material systems.
This study demonstrates that optimal thermoelectric performance in flat-band systems requires finite hybridization with dispersive states rather than perfect isolation, and highlights that electron-electron interactions significantly renormalize band structures, necessitating beyond-mean-field treatments for accurate predictions of the figure of merit.
