DOI: 10.1039/d2sm00602b
Abstract: In two dimensional nematics, topological defects are point like singularities with both a charge and a phase. We study the topological defects within curved nematic textures on the surface of a cylinder. This allows us… read more here.

DOI: 10.1103/physrevlett.126.215302
Abstract: We employ electric circuit networks to study topological states of matter in non-Hermitian systems enriched by parity-time symmetry PT and chiral symmetry anti-PT (APT). The topological structure manifests itself in the complex admittance bands which… read more here.
