Published Simulations of 'backwards time travel' can improve scientific experiments



Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics.
Published The fuel economy of a microswimmer



The amount of power a microswimmer needs to move can now be determined more easily. Scientists developed a general theorem to calculate the minimal energy required for propulsion. These insights allow a profound understanding for practical applications, such as targeted transport of molecules and substrates.
Published Surprising discovery shows electron beam radiation can repair nanostructures



In a surprising new study, researchers have found that the electron beam radiation that they previously thought degraded crystals can actually repair cracks in these nanostructures. The groundbreaking discovery provides a new pathway to create more perfect crystal nanostructures, a process that is critical to improving the efficiency and cost-effectiveness of materials that are used in virtually all electronic devices we use every day.
Published Widely tuneable terahertz lasers boost photo-induced superconductivity in K3C60



Researchers have long been exploring the effect of using tailored laser drives to manipulate the properties of quantum materials away from equilibrium. One of the most striking demonstrations of these physics has been in unconventional superconductors, where signatures of enhanced electronic coherences and super-transport have been documented in the resulting non-equilibrium states. However, these phenomena have not yet been systematically studied or optimized, primarily due to the complexity of the experiments. Technological applications are therefore still far removed from reality. In a recent experiment, this same group of researchers discovered a far more efficient way to create a previously observed metastable, superconducting-like state in K3C60 using laser light.
Published Scientists discover 'flipping' layers in heterostructures to cause changes in their properties



Transition metal dichalcogenide (TMD) semiconductors are special materials that have long fascinated researchers with their unique properties. For one, they are flat, one-atom-thick two-dimensional (2D) materials similar to that of graphene. They are compounds that contain different combinations of the transition metal group (e.g., molybdenum, tungsten) and chalcogen elements (e.g., sulfur, selenium, tellurium).
Published Bringing out the color in zinc



Researchers have synthesized a zinc complex based on two zinc centers that absorbs visible light. They demonstrated that this capability depends on the proximity of the zinc ions, where the complex responds to visible light when the zinc atoms are closer. This new property is expected to expand the utility of zinc, which already offers advantages including biological relevance, cost effectiveness, and low toxicity.
Published X-rays reveal microstructural fingerprints of 3D-printed alloy



Researchers took a novel approach to explore the way microstructure emerges in a 3D-printed metal alloy: They bombarded it with X-rays while the material was being printed.
Published Unifying matter, energy and consciousness



Understanding the interplay between consciousness, energy and matter could bring important insights to our fundamental understanding of reality.
Published Ionic crystal generates molecular ions upon positron irradiation, finds new study



The interaction between solid matter and positron (the antiparticle of electron) has provided important insights across a variety of disciplines, including atomic physics, materials science, elementary particle physics, and medicine. However, the experimental generation of positronic compounds by bombardment of positrons onto surfaces has proved challenging. In a new study, researchers detect molecular ion desorption from the surface of an ionic crystal when bombarded with positrons and propose a model based on positronic compound generation to explain their results.
Published Twisted science: New quantum ruler to explore exotic matter



Researchers have developed a 'quantum ruler' to measure and explore the strange properties of multilayered sheets of graphene, a form of carbon. The work may also lead to a new, miniaturized standard for electrical resistance that could calibrate electronic devices directly on the factory floor, eliminating the need to send them to an off-site standards laboratory.
Published New 'Assembly Theory' unifies physics and biology to explain evolution and complexity



An international team of researchers has developed a new theoretical framework that bridges physics and biology to provide a unified approach for understanding how complexity and evolution emerge in nature. This new work on 'Assembly Theory' represents a major advance in our fundamental comprehension of biological evolution and how it is governed by the physical laws of the universe.

Applying machine learning to find the properties of atomic pieces of geometry shows how AI has the power to accelerate discoveries in maths.
Published Lasers deflected using air



Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam.
Published Intense lasers shine new light on the electron dynamics of liquids



The behavior of electrons in liquids is crucial to understanding many chemical processes that occur in our world. Using advanced lasers that operate at the attosecond, a team of international researchers has revealed further insights into how electrons behave in liquids.

Researchers have developed plasmonic plastic -- a type of composite material with unique optical properties that can be 3D-printed. This research has now resulted in 3D-printed optical hydrogen sensors that could play an important role in the transition to green energy and industry.
Published Down goes antimatter! Gravity's effect on matter's elusive twin is revealed


For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.

An international research team has taken a decisive step toward a new generation of atomic clocks. The researchers have created a much more precise pulse generator based on the element scandium, which enables an accuracy of one second in 300 billion years -- that is about a thousand times more precise than the current standard atomic clock based on caesium.
