Zr concentration-dependent sub-lattice phase-field model of Hf1− <i>x</i> Zr <i>x</i> O2: Analysis of phase composition and polarization switching
We develop a sub-lattice phase-field model of Hf1−xZrxO2 incorporating zirconium (Zr) concentration (x)-dependence. Our framework expands the time-dependent Ginzburg–Landau equation to the sub-lattice...
Hysteretic excitation in non-collinear antiferromagnetic spin-torque oscillators: A terminal velocity motion perspective
We present a novel theoretical framework for non-collinear anti-ferromagnetic spin torque oscillators by unifying spin dynamics under the Poisson bracket formalism. By shifting from traditional torque...
Layer-resolved pump absorptance in spintronic/orbitronic terahertz emission modeling: A transfer matrix Poynting flux analysis method with sample-specific parameter fittings
Quantitative interpretation of thickness-dependent spintronic/orbitronic terahertz (THz) emitter (STE/OTE) experiments requires reliable knowledge of how pump energy is distributed among individual la...
Using the recurrent neural networks to predict the results of classical molecular dynamics modeling of crystalline solids
In this article, on an example of modeling the equilibrium state of crystalline copper, the possibility of predicting the atomic configuration at the next time step using data on atomic configurations...
Electrostatic rectification of Li+ transport in amorphous TiO <i>x</i> thin films grown by mist CVD
Amorphous metal oxide interlayers are widely used to stabilize Li+ transport at battery interfaces, yet the underlying transport mechanisms remain unclear. Here, Li+ transport in amorphous TiOx (a-TiO...

A scheme to transform extracellular matrices into source and sink modes engulfing cancerous cells
The frequency dependent dielectric property of biological tissues plays a pivotal role in deciphering the intricacies of electromagnetic field cancer cell interaction and propels new therapeutics in t...
Anisotropic thermal transport and thermoelectric properties of hexagonal LiSr <i>X</i> ( <i>X</i> = As, Sb, Bi)
Hexagonal LiSrX (X = As, Sb, Bi) compounds exhibit intrinsically low lattice thermal conductivity and promising thermoelectric transport properties due to their layered crystal structures and strong p...
Spectral evolution and real-space topological classification in a non-Hermitian Aubry–André–Harper model with quasiperiodic on-site potential
We present a systematic numerical study of the one-dimensional non-Hermitian Aubry–André–Harper model, which incorporates asymmetric nonreciprocal hopping and a quasiperiodic on-site potential. Using...
A data-driven framework for band-structure optimization and valley-topological control in phononic crystals
Band-structure characteristics in phononic crystals are highly sensitive to structural variations and strong multi-parameter coupling, necessitating dense sampling to effectively explore the design sp...
Influence of pre-existing negative surface charges on secondary electron emission avalanche evolution in vacuum surface flashover of spacecraft
Surface charging of dielectric materials is commonly observed in spacecraft under complex space environments. The accumulated charges on dielectric surfaces can modify the local electric-field distrib...
Electro-thermal and mechanical simulations of laser annealing perovskite films
Conventional thermal annealing of oxide thin films (&gt;600 °C) often induces interfacial diffusion and substrate degradation, compromising structural integrity. Nanosecond pulsed laser annealing...
