DOI: 10.1039/c9tc05470g
Abstract: We report on a family of all-sp2 carbon allotropes constructed by interconnected screw dislocations with complementary chiralities through atomistic calculations. The carbon allotropes have lattice periodicities defined by the interspacing among screw dislocations and are… read more here.

DOI: 10.1103/physrevb.105.115138
Abstract: The Mott transition in honeycomb compounds with significant spin-orbit coupling is explored. At finite temperatures we identify a novel semimetallic phase located between a topological insulator and a topological Mott insulator. This semimetal is characterized… read more here.
