Platinum is a Photocatalyst: Large Visible-Light Quantum Efficiency Revealed

This study challenges the conventional view of platinum as merely a passive electron sink by demonstrating that discrete Pt nanoislands on TiO₂ function as highly efficient visible-light photocatalysts with quantum efficiencies significantly surpassing those of gold.

Coherent control through phonon anharmonicity

This paper demonstrates that ultrafast double pump-probe spectroscopy can directly observe and control the anharmonicity of single Raman phonon modes in thermoelectric materials like SnTe and SnSe by measuring frequency shifts as a function of oscillation amplitude, thereby disentangling coherent contributions from quasi-harmonic effects and offering new pathways for material engineering and understanding optically induced phase transitions.

Topological switching in bilayer magnons via electrical control

This paper proposes a general strategy for the electrical control of topological magnons in bilayer ferromagnetic insulators, where a vertical electric field modulates interlayer potential and Heisenberg exchanges to tune band topology and nonreciprocal dynamics through competition with intrinsic Dzyaloshinskii-Moriya interactions.

Phase-selective orbital-charge conversion in MoTe2\mathrm{MoTe_2}

This study demonstrates that the orbital-charge conversion in MoTe2\mathrm{MoTe_2} thin films is governed by a thickness-driven structural phase transition, where the metallic 1T1T^\prime phase below a critical thickness of 4.5nm\approx 4.5\,\mathrm{nm} exhibits a dominant orbital Rashba–Edelstein response, while the semiconducting 2H2H phase above this threshold does not.
