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 α, 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—quasiparticles that are half-light and half-matter excitations ...
Imagine stacking two sheets of graphene—the 2D form of graphite, or the pencil at your hand—in which the carbon atoms form a hexagonal lattice and twist the top sheet out of alignment with the sheet below, yielding a periodic ...
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 ...
The heady math that describes how bubbles form in a glass of Champagne has inspired a framework for engineering living cells.
Spin waves, or magnons, as the elementary excitation of the magnetic system, can transfer spin angular momentum, which provides wide prospects for the Non-volatile, low-energy-consumption, high-speed and small-size microelectronic ...
A team of researchers from the European Laboratory for Non-Linear Spectroscopy, INFN, Sezione di Firenze and Università di Firenze has demonstrated a form of "vectorial" polariton by levitating a nanosphere inside of an optical ...
Lawrence Livermore National Laboratory (LLNL) scientists have experimentally tested the predictions of a 2020 study that computationally investigated the effect of melting on shock driven metal microjets. That earlier work ...
