New insight into unconventional superconductivity

The kagome pattern, a network of corner-sharing triangles, is well known amongst traditional Japanese basket weavers—and condensed matter physicists. The unusual geometry of metal atoms in the kagome lattice and resulting ...

New materials for quantum technologies

While conventional electronics relies on the transport of electrons, components that convey spin information alone may be many times more energy efficient. Âé¶¹ÒùÔºicists at the Technical University of Munich (TUM) and the Max ...

A new way to generate electricity from waste heat: Using an antiferromagnet for solid devices

Forcing electrons to flow perpendicularly to a heat flow requires an external magnetic field—this is known as the Nernst effect. In a permanently magnetized material (a ferromagnet), an anomalous Nernst effect (ANE) exists ...

Study gathers evidence of topological superconductivity in the transition metal 4Hb-TaS2

Topological superconductors are a class of superconducting materials characterized by sub-gap zero energy localized modes, known as Majorana boundary states (MBSs). These materials are promising for the development of quantum ...

Topological valley Hall edge solitons in photonics

Diffraction is a natural property of light beams that allows light to bend around obstacles. Because light serves as a carrier of information, some of the distorting effects of diffraction must be mitigated for many technological ...

Experiments reveal formation of a new state of matter: Electron quadruplets

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 ...

A kagome lattice superconductor reveals a 'cascade' of quantum electron states

Researchers have discovered a complex landscape of electronic states that can co-exist on a kagome lattice, resembling those in high-temperature superconductors, a team of Boston College physicists reports in an advance electronic ...
