Studying the parenting behavior of poison frogs using tadpole-like robots
Over the past few decades, roboticists have developed robots inspired by a wide range of animals, including dogs, snakes, birds, spiders, bats, octopus, and different types of insects. These robots were primarily designed to tackle real-world practical problems, for...
A new approach to controlling the properties of turbulence
Turbulence, a fluid motion characterized by chaotic changes in flow velocity and pressure, has been the topic of countless physics studies. Although turbulence is a very common phenomenon that occurs in nature, manipulating it and controlling its properties had so far...
Study reveals the existence of the swallowtail catastrophe in non-Hermitian systems
Researchers from the Hong Kong University of Science and Technology, Xiangtan University and Southern University of Science and Technology recently unveiled a possible connection between catastrophe theory, an area of mathematics that focuses on modeling sudden...
Mapping the curvature where electrons reside in Kagome materials
Kagome metals are a class of quantum materials with interesting properties that are characterized by a unique lattice structure resembling Japanese woven bamboo patterns of the same name (i.e., Kagome). Over the past decade, physicists have been using these materials...
A scalable method to create ferroelectric FETs based on AlScN and 2D semiconductors
A key objective in the electronics engineering field is to develop transistors and other electronic components that are increasingly compact and efficient, utilizing readily available processes and materials. Among the transistors that have been found to be...
An optical method to polarize free electrons in a laboratory setting
Polarized electrons are electrons in which spins have a "preferred" orientation or are preferentially oriented in a specific direction. The realization of these electrons has notable implications for physics research, as it can pave the way toward the creation of...
A conductive self-healing hydrogel to create flexible sensors
The first experimental observation of subpicosecond electron bunches originating from an ultracold source
Identifying new sources that produce electrons faster could help to advance the many imaging techniques that rely on electrons. In a recent paper published in Physical Review Letters, a team of researchers at Eindhoven University of Technology demonstrated the...
The observation of a quantum disordered ground state in a triangular lattice magnet
Magnetic materials with a triangular lattice have been the focus of numerous research studies, as theoretical predictions suggest that they could exhibit spin liquid states. These are quantum phases of matter that present interesting characteristics, such as quantum...
