The transition to widespread connectivity in networks is aptly described by concepts borrowed from percolation theory. Attempts to delay the transition with small interventions lead to explosive percolation, with drastic consequences for the system.
Magnons provide a route for information-processing technologies that are free from charge-related dissipations. Advances in the manipulation of magnons, and the conversion to charge currents, bring magnon-based computing closer to realization.
The discovery of spin-triplet Cooper pairs at superconductor/ferromagnet interfaces provides a route for combining superconducting and magnetic orders. Recent advances and challenges in the field of superconducting spintronics are now reviewed.
The task of integrating information into the framework of thermodynamics dates back to Maxwell and his infamous demon. Recent advances have made these ideas rigorous—and brought them into the laboratory.
Statistical mechanics is adept at describing the equilibria of quantum many-body systems. But drive these systems out of equilibrium, and the physics is far from clear. Recent advances have broken new ground in probing these equilibration processes.
