To exclude any symmetry-based phenomena, we used circularly polarized light. The Raman modes were always fitted with one Lorentzian function and linear background. The laser power value was measured using an Ophir Nova II system with photodiode sensor PD-300. References 1. Fiori, G. et al. ...
in which\({E}_{\pm }^{r,t}={E}_{x}^{r,t}\pm \,{{\mbox{i}}}\,{E}_{y}^{r,t}\)are the left (+) and right (−) circularly polarized components of the reflected (r) and transmitted (t) outgoing electric fields. When the thickness of the Chern insulators is much thin...
Due to the concentration of the different frequency components in a relatively narrow frequency range, from 140 kHz up to 180 kHz (Figure 5a), the detected values of the peak spectrum magnitudes in the frequency axis and velocity axis are slightly distributed within the circularly shaped region....
Assuming two-dimensional constellations throughout, the channel model becomes where x complex, possibly random, matrix, whose entries describe the gains of each transmission path from a transmit to a receive antenna), and z is a circularly-symmetric, complex Gaussian noise vector. The component of...
Optical pumping with up to 3.3W at 532nm produced a maximum output power of 330mW at 675nm, in a single circularly-symmetric beam with M2<2. Simultaneous pumping with three separate input beams, generated using a diffractive optical element, achieved lasing from three discrete areas of the ...
