Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions to technological problems.
Modelling shows how plasma density gradients can be tailored to compress optical pulses in the final stages of laser systems towards exawatt (1018 W) peak powers.
A large-angle twist between two bilayer graphene films makes a sensitive and broadband infrared–terahertz detector as a result of interlayer screening and a crystal field-induced bandgap.
A compact, time- and energy-efficient computing architecture — based on ferroelectric-defined reconfigurable two-dimensional photodiode arrays — is shown to be capable of in-memory sensing and computing.
Superheavy nuclei are synthesized in the laboratory through the fusion of lighter nuclei. Here the authors study multinucleon transfer and interactions during the early stages of nuclear fusion in the collision of 40Ca and 208Pb nuclei showing early onset of complexity.
In this work, authors demonstrate a low-force and energy-efficient elastocaloric air cooling approach based on coil-bending of NiTi ribbons/wires. The device achieves continuous cold outlet airflow with a temperature drop of 10.6 K and a specific cooling power of 2.5 W g−1 at a low specific driving force of 26 N g−1.
The photonic applications of hyperbolic phonon polaritons (HPhPs) in anisotropic van der Waals materials are currently limited by their low tunability. Here, the authors report the static and ultrafast wavevector modulation of HPhPs in hexagonal boron nitride by tuning the plasma frequency of doped semiconductor substrates.
Hubert Reeves, a most renowned astrophysicist for both his scientific accomplishments and outstanding outreach efforts, passed away on 13 October 2023.
