DUNKLE MATERIE. “As early as 1933, the discovery made by F. Zwicky about visible matter being only a tiny fraction of the matter in our Universe, evidenced that our understanding of the cosmos was far from being complete.” (An extraordinary man, and an extraordinary finding of dark matter, still unsolved. Note date.) https://lnkd.in/dC9btGip View in LinkedIn

This Catalan town is built on a basalt plug in a volcano crater basin, where most of the basalt columns are pentagons, with some rhomboids, not the usual hexagons." " https://lnkd.in/dtCsXNkz View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the theme of dressed photons, in a paper by a Japanese group. They outline how traditional optics has misunderstood some important truths and elaborate the experimental support for this position, and in doing so propose a new optics paradigm with practical applications.

ACCOMPLISHING THE IMPOSSIBLE. “Figure 1 shows typical experimental setups for creating a DP. Studies on DPs are now rapidly progressing, yielding innovative generic technologies of “small light”, which accomplish the impossible in a variety of application fields.” (DP = dressed photon). https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

IGNORED PARADIGM. “One should bear in mind, however, that the concept of a DP first proposed by one of the authors (M.O.) still seems to be either ignored or tacitly understood differently by the mainstream researchers in optical sciences because of the conceptual difficulty of dealing with off-shell quantities in the midst of field interactions.” (DP = dressed photon). https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

CORRECTING THE MISCONCEPTION. “We think that this kind of refusal or confusion about DPs stems from a certain degree of ambiguity in using such an abstract expression as light–matter field interactions in a nanometric space; the main purpose of the above remark is not to criticize the incorrect usage of DPs in the literature but rather to promote renewed awareness that the issue of DP phenomena addressed here is a remarkable one that cannot be understood within the conventional framework of optical theory.” (DP = dressed photon). https://www.mdpi.com/2073-8994/12/8/1244/htm View in LinkedIn

EXISTING DOGMA. “To elucidate the essence of the DP problem, we start by listing five conventional views in optics and briefly show how a DP violates them. Five conventional common views in optics.” (They are listed in the following posts; DP = dressed photon). 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

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 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
