Abstract: We numerically study the real-time dynamics of a single hole created in the $t-J$ model on a square lattice. Initially, the hole spreads ballistically with a velocity proportional to the hopping matrix element. At intermediate… read more here.

DOI: 10.1103/physrevb.104.174439
Abstract: Spin-1/2 maple leaf lattice antiferromagnets are expected to show interesting phenomena originating from frustration effects and quantum fluctuations. We report the hydrothermal synthesis of a powder sample of bluebellite Cu6IO3(OH)10Cl as a first potential candidate.… read more here.

DOI: 10.1103/physrevlett.133.086701
Abstract: We visualize antiferromagnetic domains in a representative quasi-one-dimensional S=1/2 quantum antiferromagnet, BaCu_{2}Si_{2}O_{7}, using nonreciprocal directional dichroism, which differentiates the optical absorption of a pair of antiferromagnetic domains. Opposite antiferromagnetic domains, each about submillimeter in size,… read more here.
