A newly discovered type of superconductor is also a magnet

Magnets and superconductors go together like oil and water—or so scientists have thought. But a new finding by MIT physicists is challenging this century-old assumption. In a paper appearing in the journal Nature, the physicists report that they have discovered a "chiral superconductor"—a material that conducts electricity without resistance, and also, paradoxically, is intrinsically magnetic. What's more, they observed this exotic superconductivity in a surprisingly ordinary material: graphite, the primary material in pencil lead. Graphite is made from many layers of graphene—atomically thin, lattice-like sheets of carbon atoms—that are stacked together and can easily flake off when pressure is applied, as when pressing down to write on a piece of paper. A single flake of graphite can contain several million sheets of graphene, which are normally stacked such that every other layer aligns. But every so often, graphite contains tiny pockets where graphene is stacked in a different pattern, resembling a staircase of offset layers.

“Unearthing Buried Gods.” Michael McGrath

Michael McGrath Summons Symbolism and a Folk Art Style in Expressive Paintings

November 6, 2024

Kate Mothes

From fanged cats and all-seeing ravens to anthropomorphized botanicals and disembodied faces, Michael McGrath’s uncanny works nod to the symbol-rich, flat compositions of folk art or “naïve” painting. His mixed-media works combine materials like graphite, oil paint and oil stick, ink, and acrylic on a variety of surfaces, including wood, canvas, and burlap.

Inspired by the expansive scenes of contemporary artists Peter Doig and Mamma Andersson, and self-taught artists Henry Darger (1892-1973) and William Hawkins (1895-1990), McGrath harnessed a narrative approach in his own practice. “I decided to experiment with figures and storytelling in my painting,” he tells Colossal. He also counts Jim Henson among his influences.

“Threats and competition for tiny vampires” (2023), graphite, colored pencil, and India ink on wood panel, 14 x 11 inches

Populated with an array of characters, from trees with alarmed expressions to tiny, fairy-like black critters with bulbous wings and long legs, McGrath delves into mysterious, emotional tales with plots as enigmatic as they are supernatural.

The artist’s interest in painting evolved from an early fascination with design, especially album covers and advertising in magazines like Spin and Thrasher. “I never had the patience to develop classical skills, so I focused on dimensional and collage work for a while, until I eventually decided to invest more time in painting,” he says.

McGrath’s work will be part of an online group show with MePaintsMe, Slight of Hand, which opens on November 12. In February, he will also have pieces on view in a group show at Court Tree Collective in Brooklyn.

Some memes + art from a project I’ve been calling “Nim”:

Context isn’t totally necessary, but the cliff notes are that story is set in an urban fantasy world, Nim and Lune are adopted siblings / father and daughter. They are part of a rarely-seen species who live isolated from the rest of the world and have immense magical power, but left their home in search of a better life shortly before being captured by local mad scientist Sammy. Nim was taken in by Delilah and her shapeshifting dragon son Dante after she was rescued separately from Lune.

Revolution in friction: A way to make super-smooth materials

Scientists from the Faculty of Physics and Applied Informatics at the University of Lodz have published an article on friction in the journal Small. Their research on "bismuth islands" moving on the surface of graphite confirmed the existence of a totally new form of so-called superlubricity—a friction-free contact between two solid bodies. This discovery could revolutionize the way we design nanoscale machines, and even vehicles, in the future. By understanding these processes, we can create devices that can operate much more efficiently, saving on energy and resources. Scientists led by Dr. Hab. Paweł Kowalczyk, associate professor at the University of Lodz, have discovered a new phenomenon related to the disappearance of friction—superlubricity. This special phenomenon was observed at the contact of two solid materials, bismuth and graphite.

Jeong Min Park earns 2024 Schmidt Science Fellowship

New Post has been published on https://thedigitalinsider.com/jeong-min-park-earns-2024-schmidt-science-fellowship/

Jeong Min Park earns 2024 Schmidt Science Fellowship

Physics graduate student Jeong Min (Jane) Park is among the 32 exceptional early-career scientists worldwide chosen to receive the prestigious 2024 Schmidt Science Fellows award.  

As a 2024 Schmidt Science Fellow, Park’s postdoctoral work will seek to directly detect phases that could host new particles by employing an instrument that can visualize subatomic-scale phenomena.  

With her advisor, Pablo Jarillo-Herrero, the Cecil and Ida Green Professor of Physics, Park’s research at MIT focuses on discovering novel quantum phases of matter.

“When there are many electrons in a material, their interactions can lead to collective behaviors that are not expected from individual particles, known as emergent phenomena,” explains Park. “One example is superconductivity, where interacting electrons combine together as a pair at low temperatures to conduct electricity without energy loss.”

During her PhD studies, she has investigated novel types of superconductivity by designing new materials with targeted interactions and topology. In particular, she used graphene, atomically thin two-dimensional layers of graphite, the same material as pencil lead, and turned it into a “magic” material. This so-called magic-angle twisted trilayer graphene provided an extraordinarily strong form of superconductivity that is robust under high magnetic fields. Later, she found a whole “magic family” of these materials, elucidating the key mechanisms behind superconductivity and interaction-driven phenomena. These results have provided a new platform to study emergent phenomena in two dimensions, which can lead to innovations in electronics and quantum technology.

Park says she is looking forward to her postdoctoral studies with Princeton University physics professor Ali Yazdani’s lab.

“I’m excited about the idea of discovering and studying new quantum phenomena that could further the understanding of fundamental physics,” says Park. “Having explored interaction-driven phenomena through the design of new materials, I’m now aiming to broaden my perspective and expertise to address a different kind of question, by combining my background in material design with the sophisticated local-scale measurements that I will adopt during my postdoc.”

She explains that elementary particles are classified as either bosons or fermions, with contrasting behaviors upon interchanging two identical particles, referred to as exchange statistics; bosons remain unchanged, while fermions acquire a minus sign in their quantum wavefunction.

Theories predict the existence of fundamentally different particles known as non-abelian anyons, whose wavefunctions braid upon particle exchange. Such a braiding process can be used to encode and store information, potentially opening the door to fault-tolerant quantum computing in the future.

Since 2018, this prestigious postdoctoral program has sought to break down silos among scientific fields to solve the world’s biggest challenges and support future leaders in STEM.

Schmidt Science Fellows, an initiative of Schmidt Sciences, delivered in partnership with the Rhodes Trust, identifies, develops, and amplifies the next generation of science leaders, by building a community of scientists and supporters of interdisciplinary science and leveraging this network to drive sector-wide change. The 2024 fellows consist of 17 nationalities across North America, Europe, and Asia.   

Nominated candidates undergo a rigorous selection process that includes a paper-based academic review with panels of experts in their home disciplines and final interviews with panels, including senior representatives from across many scientific disciplines and different business sectors.

Graphite

What is graphite?

Graphite which also known black leadis a natural mineral which naturally occurring form of carbon, known for its unique structure and properties. It is composed of carbon atoms arranged in a hexagonal lattice, forming flat layers of interconnected hexagons, this flat layer is known as graphene. The distance between layers is approximately 0.336 nm. Each carbon atom within a layer is bonded to three other carbon atoms, creating a strong covalent network.

The carbon atoms in graphite are arranged in layers or sheets. Each layer consists of a two-dimensional hexagonal lattice. The layers are held together by weak van der Waals forces, which allows them to easily slide past each other. This property gives graphite its distinctive slippery and lubricating feel.
