Topological Winding Numbers from Wavefront Dislocations in Local Electronic Density
Yuval Abulafia, Eric Akkermans
Topological materials are characterized by integer invariants that underpin robust quantized electronic properties, as exemplified by the Chern number in the integer quantum Hall e…

Defects Potentials for Two-Dimensional Topological Materials
Yuval Abulafia, Amit Goft, Nadav Orion +1
For non-topological quantum materials, introducing defects can significantly alter their properties by modifying symmetry and generating a nonzero analytical index, thus transformi…

Wavefronts Dislocations Measure Topology in Graphene with Defects
Yuval Abulafia, Amit Goft, Nadav Orion +1
We present a general method to identify topological materials by studying the local electronic density . More specifically, certain types of defects…
