Quantum theorists at the University of British Columbia have proposed a new approach to studying stacking ferroelectricity—spontaneous electric polarization—in layered, two-dimensional lab-grown ...

Dry stack structural elements are characterized by nonlinear stiffness that arises from geometric imperfections of their components and the absence of any bonding between them. Moreover, such elements ...

The usual approach to studying a solid in physics is to consider all the interactions acting between its atoms or molecules and then use the laws of quantum mechanics to determine the solid’s ...

Quantum geometry gives rise to many fascinating phenomena in solids that go beyond Landau theory. A general framework is now introduced to measure the quantum geometric tensor in solids — a ...

Two RIKEN physicists have established new theoretical limits for experimentally measurable quantities by viewing solids through a lens of quantum geometry. Their results shed light both on the physics ...

2D van der Waals crystals, a class of materials that exhibit strong in-plane covalent bonds and weak interlayer interactions, have recently become the focus of numerous research studies due to their ...

Figure 1: Quantum objects such as electrons, protons and neutrons are notoriously difficult to pin down due to Heisenberg’s uncertainty principle. Now, two RIKEN researchers have derived analogous ...
