Researchers have developed a charge model to describe photoexcited states of one-dimensional Mott insulators. They have also succeeded in constructing a many-body Wannier function as the localized basis state of the photoexcited states and calculating large-system, optical conductivity spectra that can be compared with experimental results.
New research overturns the belief that people with severe mental illness are incapable of effective communication with their psychiatrist, and are able to work together with them to achieve better outcomes for themselves.
Astronomers at the National Astronomical Observatory of Japan (NAOJ) have analyzed the paths of two objects heading out of the Solar System forever and determined that they also most likely originated from outside of the Solar System. These results improve our understanding of the outer Solar System and beyond.
Sand crabs, a key species in beach ecosystems, were found to have increased adult mortality and decreased reproductive success when exposed to plastic microfibers, according to a new study.
Simple LEGO bricks can be assembled to more complicated structures, which can be further associated into a wide variety of complex architectures, from automobiles, rockets, and ships to gigantic castles and amusement parks. Such an event of multi-step assembly, so-called ‘hierarchical self-assembly’, also happens in living organisms.
New Zealand media reports on chronic pain are focusing on treatments involving opioids and cannabis at the expense of best practice non-drug treatments, researchers have found.
Research has shown that students who use digital technology excessively are less motivated to engage with their studies, and are more anxious about tests. This effect was made worse by the increased feelings of loneliness that use of digital technology produced.
Hard plant foods may have made up a larger part of early human ancestors’ diet than currently presumed, according to a new experimental study of modern tooth enamel. The results have implications for reconstructing diet, and for our interpretation of the fossil record of human evolution, researchers said.
Sanitary care in ants to fight disease is known to improve the wellbeing of the colony, yet it has been unclear how social disease defense interferes with pathogen competition inside the individual host body. Biologists now revealed that collective care-giving has the power to bias the outcome of coinfections in fungus-exposed colony members.
New research shows soybean oil not only leads to obesity and diabetes, but could also affect neurological conditions like autism, Alzheimer’s disease, anxiety, and depression.
