(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 ...

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, ...

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 ...

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 ...

Axions, hypothetical subatomic particles that were first proposed by theoretical physicists in the late 1970s, remain among the most promising dark matter candidates. Physics theories suggest that the ...
