(Phys.org) —When C. K. Hong, Z. Y. Ou and Leonard Mandel demonstrated destructive quantum interference between pairs of indistinguishable bosons in their 1987 paper1, they did so with massless photons. Their protocol – christened the Hong–Ou–Mandel (HOM) effect – remained unchanged until recently, when scientists at The University of Queensland, Brisbane proposed an experiment to implement HOM in the matter-wave regime. This massive-particle version of the HOM effect uses pair-correlated atoms produced in a collision of two Bose–Einstein condensates and subjected to two laser-induced so-called Bragg pulses. (A Bose-Einstein condensate, or BEC, is a phase of matter in which bosons in a dilute gas enter the same quantum state when cooled to a temperature near absolute zero – that is, 0 K or −273.15 °C – and macroscopic-scale quantum effects appear. Bragg pulses replicate atom optics analogs of the mirror and beam-splitter elements of the photonic HOM interferometer.) By simulating the atom-optics HOM effect using colliding condensates and predicting an interference visibility of about 70%, the researchers say that their matter-wave approach may lead to stronger tests of quantum mechanics, including Bell inequality violations and the Einstein–Podolsky–Rosen paradox, the latter now being known as entanglement.

In 2006, miners discovered a hominin skullcap with peculiar morphological features in the Salkhit Valley of the Norovlin county in eastern Mongolia. It was initially referred to as Mongolanthropus and thought to be a Neandertal or even a Homo erectus. The remains of the "Salkhit" individual represent the only Pleistocene hominin fossil found in the country. The skullcap found in the Salkhit Valley in eastern Mongolia belonged to a woman who lived 34,000  years ago. Analyses showed: She had inherited about 25 percent of her DNA from Western Eurasian [Credit: Institute of Archaeology, Mongolian Academy of Sciences] Ancient DNA extracted from the skullcap shows that it belonged to a female modern human who lived 34,000 ago and was more related to Asians than to Europeans. Comparisons to the only other early East Asian individual genetically studied to date, a 40,000-year-old male from Tianyuan Cave outside Beijing (China), show that the two individuals are related to each other. However, they differ insofar that a quarter of the ancestry of the Salkhit individual derived from western Eurasians, probably via admixture with ancient Siberians. Migration and interaction "This is direct evidence that modern human communities in East Asia were already quite cosmopolitan earlier than 34,000 years ago", says Diyendo Massilani, lead author of the study and researcher at the Max-Planck Institute for Evolutionary Anthropology. "This rare specimen shows that migration and interactions among populations across Eurasia happened frequently already some 35,000 years ago". Xiahe Mandible [Credit: Menghan Qiu, Dongju Zhang,  Lanzhou University] The researchers used a new method developed at the Max-Planck Institute for Evolutionary Anthropology to find segments of DNA from extinct hominins in the Salkhit and Tianyuan genomes. They found that the two genomes contain not only Neandertal DNA but also DNA from Denisovans, an elusive Asian relative of Neandertals.  "It is fascinating to see that the ancestors of the oldest humans in East Asia from whom we have been able to obtain genetic data had already mixed with Denisovans, an extinct form of hominins that has contributed ancestry to present-day populations in Asia and Oceania", says Byambaa Gunchinsuren, a researcher at the Institute of Archaeology of the Mongolian Academy of Sciences. "This is direct evidence that Denisovans and modern humans had met and mixed more than 40,000 years ago". "Interestingly, the Denisovan DNA fragments in these very old East Asians overlap with Denisovan DNA fragments in the genomes of present-day populations in East Asia but not with Denisovan DNA fragments in Oceanians. This supports a model of multiple independent mixture events between Denisovans and modern humans", says Massilani. The research is reported in two papers in the journal Science [paper1, paper2].
