Influence of Surface Morphology on Absorptivity of Light-Absorbing Materials by Chunhui Niu, Ting Zhu, Yong Lv

“…., V-type groove surface, sinusoidal surface, and random distribution, is investigated using a rigorous electromagnetic theory and a finite element method. Influences of surface contour parameters (span distance, intersection angle, and height) and light wave parameters (incident angle and wavelength) on absorptivity are numerically simulated and analyzed for the three kinds of surfaces, respectively. …”

Thermodynamic of the f(Q) universe by Haomin Rao, Chunhui Liu, Chao-Qiang Geng

“…We show that the lowest-order correction of entropy has the same form as that in loop quantum gravity, and the critical exponents of the phase transition caused by the lowest-order correction are consistent with those in mean field theory. We then examine the thermodynamic implication of nontrivial connections. …”
