Published Golden rules for building atomic blocks
(via sciencedaily.com) Physicists have developed a technique to precisely control the alignment of supermoiré lattices by using a set of golden rules, paving the way for the advancement of next generation moiré quantum matter.
Published Quantum computer unveils atomic dynamics of light-sensitive molecules
(via sciencedaily.com) Researchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.
Published Which radio waves disrupt the magnetic sense in migratory birds?
(via sciencedaily.com) Many songbirds use the earth's magnetic field as a guide during their migrations, but radiowaves interfere with this ability. A new study has found an upper bound for the frequency that disrupts the magnetic compass.
Published Making the invisible, visible: New method makes mid-infrared light detectable at room temperature
(via sciencedaily.com) Scientists have developed a new method for detecting mid-infrared (MIR) light at room temperature using quantum systems.
Published Scientists use quantum device to slow down simulated chemical reaction 100 billion times
(via sciencedaily.com) Using a trapped-ion quantum computer, the research team witnessed the interference pattern of a single atom caused by a 'conical intersection'. Conical intersections are known throughout chemistry and are vital to rapid photo-chemical processes such as light harvesting in human vision or photosynthesis.
Published Wastewater pipe dig reveals 'fossil treasure trove'
(via sciencedaily.com) Original source A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.
Published New quantum device generates single photons and encodes information
(via sciencedaily.com) A new approach to quantum light emitters generates a stream of circularly polarized single photons, or particles of light, that may be useful for a range of quantum information and communication applications. A team stacked two different, atomically thin materials to realize this chiral quantum light source.
Published Do measurements produce the reality they show us?
(via sciencedaily.com) The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.
Published Research group detects a quantum entanglement wave for the first time using real-space measurements
(via sciencedaily.com) A team has created an artificial quantum magnet featuring a quasiparticle made of entangled electrons, the triplon.
Published Scientists develop fermionic quantum processor
(via sciencedaily.com) Researchers have designed a new type of quantum computer that uses fermionic atoms to simulate complex physical systems. The processor uses programmable neutral atom arrays and is capable of simulating fermionic models in a hardware-efficient manner using fermionic gates. The team demonstrated how the new quantum processor can efficiently simulate fermionic models from quantum chemistry and particle physics.
Published Researchers extract ancient DNA from a 2,900-year-old clay brick, revealing a time capsule of plant life
(via sciencedaily.com) Original source For the first time, a group of researchers have successfully extracted ancient DNA from a 2,900-year-old clay brick. The analysis provides a fascinating insight into the diversity of plant species cultivated at that time and place, and could open the way to similar studies on clay material from other sites and time periods.
Published Want to know how light works? Try asking a mechanic
(via sciencedaily.com) Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves.
Published Ancient metal cauldrons give us clues about what people ate in the Bronze Age
(via sciencedaily.com) Original source Archaeologists have long been drawing conclusions about how ancient tools were used by the people who crafted them based on written records and context clues. But with dietary practices, they have had to make assumptions about what was eaten and how it was prepared. A new study analyzed protein residues from ancient cooking cauldrons and found that the people of Caucasus ate deer, sheep, goats, and members of the cow family during the Maykop period (3700--2900 BCE).
Published Demon hunting: Physicists confirm 67-year-old prediction of massless, neutral composite particle
(via sciencedaily.com) In 1956, theoretical physicist David Pines predicted that electrons in a solid can do something strange. While they normally have a mass and an electric charge, Pines asserted that they can combine to form a composite particle that is massless, neutral, and does not interact with light. He called this particle a 'demon.' Now, researchers have finally found Pines' demon 67 years after it was predicted.
Published Quantum physicists simulate super diffusion on a quantum computer
(via sciencedaily.com) Quantum physicists have successfully simulated super diffusion in a system of interacting quantum particles on a quantum computer. This is the first step in doing highly challenging quantum transport calculations on quantum hardware and, as the hardware improves over time, such work promises to shed new light in condensed matter physics and materials science.
Published Unlocking chaos: Ultracold quantum gas reveals insights into wave turbulence
(via sciencedaily.com) In the intricate realm of wave turbulence, where predictability falters and chaos reigns, a groundbreaking study has emerged. The new research explores the heart of wave turbulence using an ultracold quantum gas, revealing new insights that could advance our understanding of non-equilibrium physics and have significant implications for various fields.
Published Unveiling Japan's ancient practice of cranial modification: The case of the Hirota people in Tanegashima
(via sciencedaily.com) Original source Cranial modification is a form of body alteration where the head is pressed or bound to permanently deform the skull. The practice has been reported across various cultures throughout history. Researchers report that the Hirota people -- who lived on the southern Japanese island of Tanegashima between the 3rd to 7th century CE -- also conducted cranial modification, with indication that both males and females performed the practice.
Published Sea sequin 'bling' links Indonesian islands' ancient communities
(via sciencedaily.com) Original source Microscopic analysis has revealed that trends in body ornamentation were shared across Indonesian islands.
Published Switching 'spin' on and off (and up and down) in quantum materials at room temperature
