      Study with Kagome antiferromagnets with an isotropic Heisenberg exchange J and strong easy-axis single-ion anisotropy D highlights that nontrivial ordering into a "spin-nematic" occurs whenever D dominates over J, and reveal its experiemntal signatures.

      While analysing the effects of the on-site Coulomb repulsion U on a band insulator using dynamical mean field theory (DMFT), this research finds that the gap is suppressed to zero at a critical Uc1 and remains zero within a metallic phase.

      In supercooled liquids, this research finds that the coupling rotational and translational diffusion breaks down at a lower temperature where a change occurs in the temperature dependence of the average inherent structure energy.

      Higher order intergroup covariances involving even number of qubits are necessarily positive semidefinite for N-quibit separable states, which are symmetric under permutations of the qubits.

  • Intermittency Route to Rheochaos in Wormlike Micelles with Flow-Concentration Coupling

      This research shows that the route to chaos is via intermittency in a shear-thinning wormlike micellar system of cetyltrimethylammonium tosylate, where strength of flow-concentration coupling is tuned by the addition of salt sodium chloride.

      In contrast with conventional normal metal-insulator-superconductor (NIS) junctions, the tunneling conductance of a NIS junction in graphene is an oscillatory function and zero-bias.
