Non-Heisenberg-type approximant crystals have many interesting properties and are intriguing for researchers of condensed matter physics. However, their magnetic phase diagrams, which are crucial for realizing their potential, remain completely unknown. Now, a team of researchers has constructed the magnetic phase diagram of a non-Heisenberg Tsai-type 1/1 gold-gallium-terbium approximant crystal. This development marks a significant step forward for quasicrystal research and for the realization of magnetic refrigerators and spintronic devices.

I'm excited to announce our recent open access publication in "Materials Today Physics" in collaboration with our colleagues at Tohoku University. In this paper, we unveiled the first exotic magnetic phase diagram of the non-Heisenberg Tsai-type quasicrystal approximant, using a combination of magnetization and neutron diffraction measurements. We also elucidated the phase selection rule between noncoplanar whirling antiferromagnetic and ferromagnetic orders by analyzing the relative orientation of magnetic moments between nearest-neighbour and next-nearest neighbour sites. The results should help us to better understand intriguing magnetism of not only approximant crystals but also quasicrystals themselves. We hope to advance their potential in emerging technologies like spintronics and magnetic refrigeration. I welcome connections with other researchers interested in magnetism of quasicrystals, or related topics. Please reach out if you would like to discuss collaboration opportunities!

A Leap in 2D Materials Research Really impressive work by Jani Kotakoski and his team who showed how electron microscope can be used to study single crystals and pahse transitions of noble gases encapsulated between graphene layers. The study brilliantly captures how these noble gas clusters, when sandwiched between suspended graphene sheets, reveal fascinating atomic through transmission electron microscopy. It's intriguing to see how smaller crystals follow the simple non-directional van der Waals interaction while larger ones show deviations, potentially influenced by the graphene lattice. This paper not only explored the atomic arrangement of these clusters but also explores their dynamic nature within the graphene sandwich, providing valuable insights into the solid-fluid phase transitions under varying conditions. What's particularly exciting is the potential applications of this research in condensed-matter physics and quantum information technology. The paper opens doors to a largely unexplored area of encapsulated 2D van der Waals solids, presenting opportunities for groundbreaking research in material science. The ability to create and analyze such structures at room temperature, thanks to graphene's unique properties, is a testament to the potential of electron microsocpy to explore the new vistas of physics research and make and break atomic strucutres. Kudos to Jani and his team for this remarkable contribution, which is sure to inspire further exploration in the realm of 2D materials. https://lnkd.in/erftUB3V

Physicist Dr. Jan Vogelsang, from the Carl von Ossietzky University of Oldenburg, and an international team have achieved groundbreaking insights into the ultrafast movements of electrons within zinc oxide crystals. Using advanced techniques, including attosecond physics and photoemission electron microscopy (PEEM), the researchers captured electron dynamics with nanometer-scale spatial resolution and unprecedented temporal accuracy. The study, featuring experiments at Lund University, opens new avenues to understand electron behavior in nanomaterials and emerging solar cells. The successful combination of attosecond pulses and PEEM heralds a new era for investigating light-matter interactions at the atomic level. https://lnkd.in/eVVvjecS #Physics #MaterialsScience #Solar #IP #VC #Patents #DeepTech

⬇️Monday Physics⬇️ 🌟 ATOM BONDING in REAL TIME 🌟 Ever seen an atom bonding in real time , scientists have captured real-time footage of ATOMS bonding and breaking at a scale half-a-million times smaller than the width of a human hair. 😳🤯👌⚗️🧪🧫 Using advanced microscopy, researchers filmed the bond between two rhenium atoms. In the video, these atoms (appearing as black blobs) bond and break between 0.1 and 0.3 nanometers. Atoms, the building blocks of everything, control phenomena from chemical reactions in our bodies to how the sun generates energy. This incredible footage shows rhenium atoms trapped inside carbon nanotubes. One atom escaped, wedged between two nanotubes, causing the bond to break and reform. As they bond, the atoms stretch from circular to oval shapes and vibrate intensely. When the bond breaks, this vibration stops. The electron microscope not only recorded this but also provided the energy to make it happen! Rhenium (Re), a silvery-white metal with a high atomic number, was chosen because its larger size makes it more visible under the microscope. Each atom is just 205 picometers in diameter! The researchers highlight that the electron beam’s dual role as an energy source and imaging tool advances our understanding of metallic bonding, revealing that these bonds can change over time due to the electron beam. This tech opens new doors for observing atomic mechanisms, aiding in the development of materials, nanotechnology, and chemistry as a whole. 🌐🔬 Read the research material https://lnkd.in/dEFaptYg #physics #synthesis #nanotechnology #nanomaterials #nanoparticles #nanomedicine #polymers #nanochemistry #nanoscience #inorganicchemistry #chemistry #newmolecules #nanocomposite #microscopy

"High-energy neutrino interactions have been observed within a particle collider for the first time, according to findings detailed in a study that marks an important new milestone in particle physics. Neutrinos are neutral sub-atomic particles that play a significant role in the Standard Model of particle physics. Despite their abundance in the universe, they are sometimes called “ghost particles” given that they seldom interact with matter, making them difficult to detect. For particle physicists, understanding these rare neutrino interactions with other forms of matter is a significant pursuit toward gaining a better understanding of our universe. Such studies may help answer questions like why particles have mass and why there is more matter than antimatter. Now, new research led by professors Akitaka Ariga and Tomoko Ariga that employed the Forward Search Experiment (FASER) at CERN’s Large Hadron Collider (LHC) resulted in the successful detection of electron and muon neutrinos at energy ranges that have never previously been explored."

Particle "jets" are the most abundantly produced objects in the ATLAS experiment and are crucial for understanding numerous physics processes. Researchers use jets in searches for new physics, measurements of Standard Model properties, and more. Precisely understanding jet properties can be challenging. At the BOOST 24 conference, ATLAS scientists presented two innovative approaches for more accurately quantifying jet properties. These new techniques are a significant advancement in the field.
