This Collection of papers highlight outstanding research on Variational Quantum Algorithms published Physical Review Research in the last few years.

Non-Hermitian physics has moved from a mathematical curiosity to one of the most active frontiers at the interface of condensed matter, photonics, and quantum science.

This Collection offers an early glimpse into how artificial intelligence and machine learning can further unlock the potential of density functional theory, a highly successful computational method with broad applications.

Climate Science is a growing field that is attracting colleagues from many disciplines. This Collection, a joint effort by Physical Review E, Physical Review Research, and PRX Energy curated by Prof. Justin Burton from Emory University, aims at providing a survey of the diverse range of topics that scientists with a connection to Physics are exploring in this exciting area of research. This includes climate and related geosciences, sustainability, energy, and material science, and may include fundamental as well as applied research.

Every article in this Collection was subjected to a rigorous peer review process, upholding the high standards applied to all papers. The Physical Review E, Physical Review Research, and PRX Energy editorial teams managed the peer review and made all editorial decisions.

Physics of Neuroscience has emerged as an area of research at the edge of a breadth of multiple disciplines, ranging from statistical physics and computer science all the way to biomedical research. As a venue committed to multi- and interdisciplinary work with a connection to physics, Physical Review Research is delighted to start a Collection, organized by guest editors David Schwab and Carina Curto, to host the outstanding research that is being produced in this field and to invite this burgeoning community to partner with us in our mission to disseminate novel and significant content to the public.
