This Perspective surveys the role of thermal nonlinearity in figures of merit through a multiscale physical understanding to advance heat harvesting technologies beyond linear processes, focusing on ‘nonlinear heat harvesting’, which potentially contributes to sustainable energy transition and decarbonization...
The physics of two-photon scattering is richer, as the energy of the individual photons is not necessarily conserved, which leads to photon correlations. The two-photon scattering matrix has previously been computed16,19, but here we diagonalise the scattering matrix and show that the two-photon...

In the pursuit of sustainable energy, some inventors think big. Zhiyu (Jerry) Hu, Ph.D., thinks small — at the nanoscale. His work in thermoelectric devices is transforming how we understand and harvest energy, turning minute temperature differences into reliable power sources. For much of his...

The fusion process, which is the mechanism by which the sun and stars generate their energy, was the basis for development of the hydrogen bomb in the 1950s, and there has been intense research during the subsequent decades to harness thermonuclear fusion as a power source. At the same time...
Why does electric potential energy increase if you move against the field? My understanding of this question is that, if you have a proton standing against a positive electric field, and move it in the opposite direction of the field, you're putting in work and therefore should have greater...

Structure and inference in hypergraphs with node attributes Many networked datasets encoded with hypergraphs include additional node attributes, such as roles in a workplace, that can enhance the understanding of higher-order interactions. This study presents a model that integrates higher-order interactio...
Graph states are a broad family of entangled quantum states, each defined by a graph composed of edges representing the correlations between subsystems. Such states constitute versatile resources for quantum computation and quantum-enhanced measurement.
