The neutron and the positron were both discovered in 1932. This month we look back at these discoveries and find that we have more in common with early 20th century physicists that one might suspect.
Machine learning methods have proved powerful in particle physics, but without interpretability there is no guarantee the outcome of a learning algorithm is correct or robust. Christophe Grojean, Ayan Paul, Zhuoni Qian and Inga Strümke give an overview of how to introduce interpretability to methods commonly used in particle physics.
Gregory White discusses process tensor tomography, a method to characterize non-Markovian dynamics, which can find applications in quantum technologies and the study of open quantum systems.
The first confirmed discovery of a planet outside our Solar System was announced 30 years ago. Since then, technical developments have enabled detection of thousands of exoplanets.
New approaches to integrate high-dimensional recordings of brain activity with single-neuron resolution with simultaneous recordings of natural animal behaviour enable the study of brain-wide activity in small animals including worms, flies and fish during behaviours and decision-making. This Review surveys experimental and theoretical approaches that have opened this area of systems neuroscience.
Multi-messenger observations of gravitational waves and electromagnetic radiation directly probe the synthesis of heavy elements in the Universe. This Review summarizes recent results and charts future challenges and opportunities for identifying the astrophysical origin of roughly half of the elements heavier than iron.
Mastering thermal conductivities of materials under pressure is extremely important for managing thermal processes, understanding the thermal transport mechanisms and for potential technological applications. This Review surveys the progresses in technique developments, research results and scientific implications in this field.
Electric-double-layer transistors and ionic field-effect transistors enable continuous tuning of carrier densities in 2D superconductors, which are essential for studying novel quantum phenomena and finding new high-temperature superconductors. This Review summarizes recent advances and future development paths for electric-field-gated superconductivity in various ultrathin superconducting materials, including iron-based superconductors, transition-metal dichalcogenides, honeycomb bilayer superconductors and cuprates.
