The observation of a quantum disordered ground state in a triangular lattice magnet

Posted by in categories: materials, quantum physics

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 entanglement and fractionalized excitations.

While there have been numerous experimental efforts aimed at observing these fascinating phases in materials with a triangular lattice, this has so far proved to be very challenging. A key reason for this is that weak spin-orbit coupling and other perturbations in these materials typically result in conventional spin freezing or .

Researchers at University of California, Boston College, Oak Ridge National Laboratory and the National Institute of Standards and Technology were recently able to produce a quantum disordered ground state in the triangular lattice-magnet NaRuO2. Their findings, published in Nature Physics, suggest that this state was enabled by the cooperative interplay between and correlation effects in the magnetic material.

Scientists find first evidence for new superconducting state in Ising superconductor

Posted by in categories: materials, physics

In a ground-breaking experiment, scientists from the University of Groningen, together with colleagues from the Dutch universities of Nijmegen and Twente and the Harbin Institute of Technology (China), have discovered the existence of a superconductive state that was first predicted in 2017.

They present evidence for a special variant of the FFLO superconductive state in the journal Nature. This discovery could have significant applications, particularly in the field of superconducting electronics.

The lead author of the paper is Professor Justin Ye, who heads the Device Physics of Complex Materials group at the University of Groningen. Ye and his team have been working on the Ising superconducting state. This is a special state that can resist magnetic fields that generally destroy , and that was described by the team in 2015.

Alleged Apple Mixed Reality Headset Material Cost Leaks Out

Posted by in categories: augmented reality, materials

Self-described mixed reality nerd, Brad Lynch, has tweeted out several interesting details about Apple’s yet-to-be announced VR/AR headset. He has managed to compile information from several sources — mostly reports produced by hardware analysts based in China. His summation of the leaked info states: “The Apple HMD’s Bill of Materials (BoM) cost to be about $1500–1600 (USD). This is about double the reported BoM for the (Meta) Quest Pro (which was 800 dollars including the controllers and charging pad).”

3D printing of unsupported multi-scale and large-span ceramic via near-infrared assisted direct ink writing Communications

Posted by in categories: 3D printing, materials

In the three-dimensional printing process of ceramic with low-angle structures, additional supporting structures are usually employed to avoid collapse of overhanging parts. However, the extra supporting structures not only affect printing efficiency, but the problems caused by their removal are also a matter of concern. Herein, we present a ceramic printing method, which can realize printing of unsupported multi-scale and large-span ceramics through the combination of direct ink writing and near-infrared induced up-conversion particles-assisted photopolymerization. This printing technology enables in-situ curing of multi-scale filaments with diameters ranging from 410 µm to 3.50 mm, and ceramic structures of torsion spring, three-dimensional bending and cantilever beam were successfully constructed through unsupported printing. This method will bring more innovation to the unsupported 3D manufacturing of complex shape ceramics.


In 3D ceramic printing, the need for additional supports can increase processing time and introduce defects during post-processing removal. Here, authors merge direct ink writing and up-conversion particles-assisted photopolymerization under near-infrared irradiation for support-free printing with controlled curing rates reducing material waste, printing time, and post-processing steps.

Researchers discover superconductive images are actually 3D and disorder-driven fractals

Posted by in categories: materials, quantum physics

Meeting the world’s energy demands is reaching a critical point. Powering the technological age has caused issues globally. It is increasingly important to create superconductors that can operate at ambient pressure and temperature. This would go a long way toward solving the energy crisis.

Advancements with superconductivity hinge on advances in . When electrons inside of quantum materials undergo a phase transition, the electrons can form intricate patterns, such as fractals. A fractal is a never-ending pattern. When zooming in on a fractal, the image looks the same. Commonly seen fractals can be a tree or frost on a windowpane in winter. Fractals can form in two dimensions, like the frost on a window, or in three-dimensional space like the limbs of a tree.

Dr. Erica Carlson, a 150th Anniversary Professor of Physics and Astronomy at Purdue University, led a team that developed theoretical techniques for characterizing the fractal shapes that these electrons make, in order to uncover the underlying physics driving the patterns.
