Much of the rich phenomenology of active matter can be traced back to violations of time-reversal symmetry and departure from Boltzmann statistics. This Review disentangles these nonequilibrium signatures for interacting and dilute systems, in the presence of obstacles and external potentials.
Quantum photonics offers an integrated and scalable approach to quantum information processing and communication. This article summarizes the state of the art and provides an outlook on future challenges and opportunities for quantum photonics based on 2D materials.
Spintronic properties of layered materials combining magnetism and strong spin–orbit coupling can be tailored by proper optimization of chemical interactions and structural material symmetries. This Review draws a route to achieving best performing material design for reaching the upper limit of spin–orbit torque efficiency in switching magnetization.
