Physicists report emergence of ferromagnetism at onset of Kondo breakdown in moiré bilayer lattices

Moiré superlattices are materials consisting of two layers stacked on top of each other with either a small rotational misalignment or a lattice mismatch between them. The Kondo lattice model, on the other hand, describes ...

The spontaneous emergence of 1D superconducting stripes at a 2D interface in an oxide heterostructure

Unconventional superconducting states are states of superconductivity rooted in physical processes that do not conform with the conventional theory of superconductivity, namely Bardeen, Cooper and Schrieffer (BCS) theory. ...

A spontaneous topological Hall effect driven by a non-coplanar antiferromagnetic order in van der Waals materials

Ferromagnets are materials that become magnetized and remain so while they are exposed to an external magnetic field. In these materials, electric currents typically induce a so-called transverse Hall voltage (i.e., a voltage ...

Evidence of excitonic insulators in moiré superlattices

Excitons are quasiparticles that are formed in insulators or semiconductors when an electron is promoted to a higher energy band, leaving a positively charged hole behind.
