(a) Schematics of nonreciprocal transports by fluctuating Cooper pairs. (b) Observed amplitude of nonreciprocity in the chiral organic superconductor in comparison with polar inorganic superconductors ...

Weyl semimetals. Courtesy: Haim Beidenkopf, the Weizmann Institute of Science Topological materials can be insulating in the bulk but can conduct electricity extremely well on their edge via special, ...

Adding a Schottky junction to certain crystals can turn them into piezoelectric or pyroelectric crystals, even if they were unaffected by deformation or heat before, according to the the University of ...

In this paper, we demonstrate computationally the existence of magnetoelectric multipoles, arising from the second-order term in the multipole expansion of a magnetization density in a magnetic field, ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are polar ...

Mild-mannered Dr. Jekyll and malicious Mr. Hyde were opposite aspects of the same man, and their story ended in tragedy because the two couldn’t peacefully coexist. Most materials, too, are capable of ...

Earlier this month, a sudden atmospheric warming event caused the Arctic's polar vortex to reverse its trajectory. The swirling ring of cold air is now spinning in the wrong direction, which has ...

Professor James Rondinelli, Research Assistant Professor Danilo Puggioni, Lauren Walters (PhD '22) Recent work from Northwestern Engineering’s James Rondinelli could lead to a new class of metals that ...
