New superlattice material for future energy efficient devices

A team of international physicists including Jennifer Cano, Ph.D., of Stony Brook University, has created a new material layered by two structures, forming a superlattice, that at a high temperature is a super-efficient insulator ...

New advance in superconductors with 'twist' in rhombohedral graphite

An international research team led by The University of Manchester has revealed a nanomaterial that mirrors the "magic angle" effect originally found in a complex man-made structure known as twisted bilayer graphene—a key ...

Light swirls provide insights into the quantum world

A new method uses swirls of light to enable researchers to observe previously invisible quantum states of electrons. The method was developed by physicists from Martin Luther University Halle-Wittenberg (MLU) and an international ...

Manifestation of quantum distance in flat band materials

The geometry of an object indicates its shape or the relationship of its parts to each other. Did you know that the electrons in solids also have geometric structures? In quantum mechanics, an electron in solids takes the ...

When Dirac meets frustrated magnetism

The fields of condensed matter physics and materials science are intimately linked because new physics is often discovered in materials with special arrangements of atoms. Crystals, which have repeating units of atoms in ...

John Tyndall: the forgotten co-discoverer of climate science

It is surprising that the Irish scientist John Tyndall, born 200 years ago on August 2 1820, is not better known. This is despite the existence of the Tyndall Centre for Climate Change Research, the Tyndall National Institute ...

Research team exactly solves experimental puzzle in high temperature superconductivity

Forty-five years after superconductivity was first discovered in metals, the physics giving rise to it was finally explained in 1957 at the University of Illinois at Urbana-Champaign, in the Bardeen-Cooper-Schrieffer (BCS) ...

Using protons to tune interlayer forces in van der Waals materials

A Chinese-Australian collaboration has demonstrated for the first time that interlayer coupling in a van der Waals (vdW) material can be largely modulated by a protonic gate, which inject protons to devices from an ionic ...
