  • Solutions of computations can be encoded in the ground state of many-body spin models. Here the authors show that solutions to generic reversible classical computations can be encoded in the ground state of a vertex model, which can be reached without finite temperature phase transitions.

  • Fractional Chern insulators, and their time-reversal analogs, fractional topological insulators, are realizations of topological order in flat-band electronic systems; while the former have been realized experimentally in twisted bilayer MoTe2, the latter have remained more elusive. Here, using exact diagonalization calculations, the authors propose routes towards engineering fractional topological insulators in twisted bilayer MoTe2 and other moiré materials.

  • Here, the authors present results of the ZiBRA-2 project (https://www.zibra2project.org) which is an arbovirus surveillance project, across the Midwest of Brazil using a mobile genomics laboratory, combined with a genomic surveillance training program that targeted post-graduate students, laboratory technicians, and health practitioners in universities and laboratories.

  • This study introduces and validates a reconfigurable metastructure that uses electromagnetic waves to perform analog complex-valued mathematical computations. This device executes both stationary and non-stationary algorithms, such as matrix inversion and optimization.

  • The non-zero geometric phase acquired by the braiding of vortex modes in photonic waveguide lattices demonstrates their potential to serve as a platform for the study of both Abelian and non-Abelian braiding in bosonic systems.

  • A theoretical study proposes that magnetic monopoles may appear not as elementary but as emergent particles in complex, strongly-correlated magnetic systems such as spin ice, in analogy to fractional electric charges in quantum Hall systems. This theory explains a mysterious phase transition in spin ice that has been observed experimentally.
