The combined observation of GW170817 and its electromagnetic counterpart GRB170817A reveals that gravitational waves propagate at the speed light in high precision. We apply effective field theory approach to investigate experimental consequences for $f(T)$ gravity. find within gravity is exactly equal speed, hence constraints from are trivially satisfied. results verified through standard analysis cosmological perturbations. Nevertheless, by examining dispersion relation frequency waves, we...

Abstract The in‐plane anisotropic feature of 2D layered materials has captured enormous research interest due to their application in polarization‐sensitive photodetection. Here, silicon phosphide (SiP), as a novel member group IV–V materials, is first introduced the family with high anisotropy. low‐symmetry structure, optical and optoelectronic properties are investigated systematically. Impressively, photodetectors based on SiP demonstrate performance low dark current, fast response speed...

One is decoupling time Compton scattering heating, other stems from direct change optical depth due to expansion rate Universe. After that, investigate IDE models illustrate tension between results...
