Propagation of laser-generated GHz surface acoustic wavepackets in FeRh/MgO(001) below and above the antiferromagnetic-ferromagnetic phase transition

This study experimentally demonstrates that laser-generated gigahertz surface acoustic wavepackets in FeRh/MgO(001) exhibit tunable excitation efficiency and anisotropic dispersion characteristics driven by the material's antiferromagnetic-to-ferromagnetic phase transition, highlighting its potential for magnetoacoustic spintronic applications.

Spontaneous Emission, Free Energy, and Relaxation-Limited Processes in Setting Limits on Solar Energy Conversion Efficiency

This paper proposes a simplified free-energy framework that establishes a theoretical thermodynamic maximum for solar energy conversion at approximately 74%, while acknowledging that practical limits like the Shockley-Queisser limit (~33%) and specific processes such as spontaneous emission and nonradiative losses currently constrain achievable efficiencies to lower values.

Optical Modulation Due to Energy Exchange Between Photonic and Exciton Modes in the Intermediate Coupling Regime

This paper demonstrates a scheme for actively tunable optical modulation in the near-infrared region by exploiting energy exchange between photonic and exciton modes in the intermediate coupling regime of a squaraine-dye based photonic structure, thereby overcoming the limitations of low absorption and slow response in traditional organic optoelectronic devices.
