Wannier states and schematic phase diagram. (a) Wannier states and a typical moiré pattern. The yellow and green blobs schematically represent the shape of Wannier orbitals on the BA and AB sublattices, respectively. (b) Schematic representation of the six-phase registry of AB-BA sites. The vertices of the triangle correspond to the three charge lobes. (c) Proposed phase...
Credit: Unsplush.Topological quantum materials are viewed as a promising prospect for energy-efficient electronics and advanced technology in the future. Among their remarkable features is the ability to conduct spin-polarized electrons on their surface, despite being non-conductive in their interior.To better grasp this concept, it's important to understand that spin-polarized electrons possess intrinsic angular momentum,...
To study superconducting materials in their “normal,” non-superconducting state, scientists usually switch off superconductivity by exposing the material to a magnetic field, left. SLAC scientists discovered that turning off superconductivity with a flash of light, right produces a normal state with very similar fundamental physics that is also unstable and can host brief flashes...

In their paper publicized in the journal Nature, the group explains their simulator and exactly how it could be used. Silke Weinfurtner, with the College of Nottingham, has published a...

Researchers at Rochester’s Laboratory for Laser Energetics used the same setup at a recent study to create superionic ice, shown here in this artistic rendering. In that instance, the ice was not stable.

The electrons of some metal oxides, due to their vast effective mass when combined with the ionic lattice of the material, can not comply with the electric field of light and allow it to pass through the material. Transparent and conductive materials are made use of in smartphone touch displays and solar panels for...
The symmetry in dynamic development found in many natural events aid scientists in their comprehension of a system's fundamental mechanism. These symmetries, nevertheless, are not always obtained in quantum physics. For the first a period of time physicists from Heidelberg College's Center for Quantum Dynamics demonstrated the theoretically predicted divergence from traditional symmetry in...
The projections of a study from 2020 that computationally evaluated the influence of melting on shock-driven metal microjets were experimentally corroborated by scientists at Lawrence Livermore National Laboratory (LLNL). According to a previous investigation, melting the foundation material did not always result in an important rise in jet mass.The LLNL, led by David Bober,...
A team of researchers from the College of Tsukuba's Division of Quantum Condensed Issue Physics has devised a new theory of superconductivity. Based on the estimation of the 'Berry connection,' this model contributes far more to explaining new findings from experiments than the current theory. The research could enable future electrical grids to send...
