Topology in optics and photonics has been a hot topic since 1890 where singularities in electromagnetic fields have been considered. The recent award of the Nobel prize for topology developments in condensed matter physics ...
Superconductivity鈥攚here electrical resistance drops and current continues without power鈥攊s a unique property used to enable MRI machines and particle accelerators, but its temperature-based restrictions have limited applications. ...
Carbon is not the shiniest element, nor the most reactive, nor the rarest. But it is one of the most versatile.
The central principle of superconductivity is that electrons form pairs. But can they also condense into foursomes? Recent findings have suggested they can, and a physicist at KTH Royal Institute of Technology today published ...
Over the past few decades, some physicists worldwide have been trying to use the second layer of 4He films adsorbed on a graphite substrate to study the interplay between superfluid and supersolid phases of matter. Some teams ...
Scientists have known for a long time that magnetism is created by the spins of electrons lining up in certain ways. But about a decade ago, they discovered another astonishing layer of complexity in magnetic materials: Under ...
Quantum electrodynamics (QED) is the fundamental quantum theory governing the behavior of charged particles and light in vacuum. The strength of the interactions in QED is quantified by the fine structure constant 伪, which ...
Researchers from Skoltech and the University of Southampton, U.K., have used all-optical methods to create an artificial lattice whose nodes house polaritons鈥攓uasiparticles that are half-light and half-matter excitations ...
Imagine stacking two sheets of graphene鈥攖he 2D form of graphite, or the pencil at your hand鈥攊n which the carbon atoms form a hexagonal lattice and twist the top sheet out of alignment with the sheet below, yielding a ...
Electrons flow through most materials more like a gas than a fluid, meaning they don't interact much with one another. It was long hypothesized that electrons could flow like a fluid, but only recent advances in materials ...
