GOLDEN HONEYCOMB. “Graphene, a one-atom thin material with carbon atoms arranged in honeycomb lattice, at its perfect state, has a linear Dirac cone in its electronic structure exhibiting ambipolar electric field effect, high electron mobility, high thermal conductivity, and room temperature quantum hall effect.” https://link.springer.com/article/10.1557/s43577-021-00135-y View in LinkedIn

DIFFICULT PERFECTION. “In reality, it remains a challenge to obtain large-scale, perfect graphene. Unintentional ad-atom doping, point defects, dislocations, and grain boundaries exist in graphene.” https://link.springer.com/article/10.1557/s43577-021-00135-y View in LinkedIn

SO ENDS this first of two weekends on the virtues of imperfections and strange emergent optical properties caused by interference patterns from waves of light reinforcing or cancelling each other like ripples in a pond. https://link.springer.com/article/10.1557/s43577-021-00135-y View in LinkedIn

FOSSILS, BY OGDEN NASH (1949)" "" "At midnight in the museum hall" "The fossils gathered for a ball" "There were no drums or saxophones," "But just the clatter of their bones," "A rolling, rattling, carefree circus" "Of mammoth polkas and mazurkas." "Pterodactyls and brontosauruses" "Sang ghostly prehistoric choruses." "Amid the mastodontic wassail" "I caught the eye of one small fossil.“" "“Cheer up, sad world,” he said, and winked—" "“It’s kind of fun to be extinct.”" " https://lnkd.in/em4YdKSk 1-16 View in LinkedIn

ANTIMATTER ISLANDS. “The lack of unambiguous annihilation signatures from γ-ray sky surveys led various authors to conclude that the distance to any hypothetical domain dominated by primordial antimatter must be comparable to the horizon scale.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

TWO SOURCE OPTIONS. “The detection of anti-4He or heavier nuclei would point to the existence of primordial antimatter from the Big Bang nucleosynthesis, while heavier particles such as antimatter 12C would point to the existence of stellar nucleosynthesis, or dense lumps of antimatter at galactic scale.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

EXTREME RARITY. “Very recently, tantalizing hints of anti-3He and anti-4He candidates have been presented by the AMS-02 magnetic spectrometer. Considering the huge helium statistics, about one antihelium candidate out of 100 million helium events, a daunting simulation effort is required to exclude misidentification of these events.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

THEORETICAL SUPPORT. “Dark matter In spite of the lack of evidence for Beyond-Standard-Model (BSM) particles from experiments at the Large Hadron Collider (LHC), TeV-scale models of DM particles are nicely supported by cosmological constraints.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

THE KEY. “The most promising channels for indirect DM searches are those involving antimatter in the final state, e.g. elementary antiparticles such as e+, anti-p or anti-nuclei such as anti-D, anti-3He.” (DM = dark matter). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn
