Magnetically Programmable Surface Acoustic Wave Filters: Device Concept and Predictive Modeling

This paper proposes and models a magnetostrictive surface acoustic wave (SAW) filter that achieves programmable frequency-selective attenuation by controlling the magnetic alignment of exchange-decoupled Co/Ni islets on a LiTaO3_3 substrate, predicting a transmission change of 52.0 dB/mm at 3.8 GHz through extended finite-difference simulations of magnetoelastic interactions.

Point-contact enhanced superconductivity in trigonal PtBi2: quest for the origin of high-Tc

This study demonstrates that point-contact measurements on trigonal PtBi2 using both normal and ferromagnetic tips significantly enhance the superconducting critical temperature up to 8 K and the critical magnetic field, likely due to strain effects, suggesting the material's potential for realizing topological superconductivity at more accessible temperatures.

Transition Metal Dichalcogenide Excitons in Periodic Electrostatic Potentials: Center-of-Mass Models

This paper demonstrates that applying periodic electrostatic potentials to 2D transition-metal dichalcogenide semiconductors induces significant valley splitting and selective dispersion in excitons, potentially enabling true Bose condensation and superfluidity in two dimensions by creating a non-degenerate, linearly dispersing ground state.
