Demon hunting: Âé¶¹ÒùÔºicists confirm 67-year-old prediction of massless, neutral composite particle

In 1956, theoretical physicist David Pines predicted that electrons in a solid can do something strange. While they normally have a mass and an electric charge, Pines asserted that they can combine to form a composite particle ...

Âé¶¹ÒùÔºicists open new path to an exotic form of superconductivity

Âé¶¹ÒùÔºicists have identified a mechanism for the formation of oscillating superconductivity known as pair-density waves. Âé¶¹ÒùÔºical Review Letters published the discovery, which provides new insight into an unconventional, high-temperature ...

In some materials, immutable topological states can be entangled with other manipulable quantum states

Rice University physicists have shown that immutable topological states, which are highly sought for quantum computing, can be entangled with other manipulable quantum states in some materials.

Many-body interactions feel the heat: Introducing thermal field theory

Quantum field theory is a framework used by physicists to describe a wide range of phenomena in particle physics and is an effective tool to deal with complicated many-body problems or interacting systems.

Study shows performance of photodetector heterojunctions varies with carbon nanotube diameter

Junctions between the two different materials, single-wall carbon nanotubes (SWCNTs) and perovskite (CsPbBr3) quantum dots (QDs)—a mechanically stable and easily customized photovoltaic material that creates an electrical ...

Study finds no evidence of universal topological signatures in high harmonic generation

Topology plays an enormous role in modern condensed matter physics and beyond. It describes how solid materials can combine two very different and somewhat contradictory properties—for example, topological insulators are ...

Team creates simple superconducting device that could dramatically cut energy use in computing

MIT scientists and colleagues have created a simple superconducting device that could transfer current through electronic devices much more efficiently than is possible today. As a result, the new diode, a kind of switch, ...

Researchers create class of tiny polarization structures called solitons

New theoretical and experimental physics research shows the first ever creation of a diverse range of fine-sized, special polarization structures known as solitons in a multiferroic material. While solitons have been previously ...

An inhomogeneous Dirac cone system gives rise to in-plane chiral Landau levels

Chiral zeroth Landau levels are topologically protected bulk states that propagate in a single direction. In the field of quantum field theory and condensed matter physics, these levels are crucial for breaking chiral symmetry ...

Âé¶¹ÒùÔºicists rediscover a discarded theory to solve a mystery of how glass damping sound

For about half a century, physicists have puzzled over vibrations in glass at low temperatures. The reason: Glass carries sound waves and vibrations differently than other solids—it "vibrates differently." But why? And ...
