COMMON VIEW IV. “An electron cannot be optically excited if the transition between the two electric energy levels is electric dipole forbidden.” https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

COMMON VIEW III. “For optical excitation of an electron, the photon energy must be equal to or higher than the energy difference between the relevant two electronic energy levels.” https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

COMMON VIEW II. “Light cannot be used for imaging and fabrication of sub-wavelength-sized materials. Furthermore, light cannot be used for assembling and operating sub-wavelength-sized optical devices.” https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

COMMON VIEW I. “Light is a propagating wave that fills a space. Its spatial extent (size) is much larger than its wavelength.” https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

QUANTUM-CLASSIC BRIDGE. “This fact is the crux of the mathematically reformulated “quantum-classical” correspondence explained in the Micro-Macro duality proposed by one (I. O.) of the present authors.” https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

EXPLANATION. “The emergence of characteristic structures where “invisible” microscopic levels become “visible” to us is due to the sector structure arising from the spectral decomposition of the center of the observable algebra. Each sector labeled by macroscopic order parameters is mutually disjoint owing to the absence of intertwiners between different sectors at the microscopic level.” https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

NEW THEORY. “In our new theory on DPs, we have introduced a new mathematical formulation called the Clebsch dual field, and some of the important outcomes derived from the formulation will be used in our arguments without detailed explanation; hence, we reserve the Method section until the end to give a revised concise explanation as background information for interested readers.” (DP = dressed photon). https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

REVIEW. “In view of the unfamiliarity in the science community at large with the relevant subjects, we recapitulate the important points to make this article self-contained, on the basis of the latest tutorial paper on DPs, which summarizes most of the results reported in a series of works.” (DP = dressed photon). https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

NOVEL PROPERTIES.”Their output optical powers are as high as 2 W: Infrared Si lasers have also been developed whose CW output optical power is as high as 100 W, and the threshold current density is as low as 60 A/cm at room temperature. Their high power and low energy consumption factors are 10(4) and 0.05, respectively, relative to those of the conventional single-stripe double heterojunction-structured semiconductor lasers fabricated using the direct-transition-type compound InGaAsP. Furthermore, novel polarization rotators have been developed using crystalline SiC that exhibit a gigantic ferromagnetic magneto-optical effect.” https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

INNOVATION 3). “Light-emitting devices using indirect-transition-type semiconductors. These devices are based on the intrinsic nature of a DP that is contrary to V. Infrared light-emitting diodes using crystalline silicon (Si) have been realized. For their fabrication, a method of DP-assisted annealing has been invented to autonomously control the spatial distribution of the dopant atoms on which DPs are created and localized (Figure 1d).” (DP = dressed photon). https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn
