Author(s): Francesco Campaioli, Stefano Gherardini, James Q. Quach, Marco Polini, and Gian Marcello AndolinaStorage of energy in quantum devices is of practical relevance for applications in quantum technologies. The topic attracts attention also of a more foundational character due to the possibility that the charging power and work extraction can...

Author(s): Patryk Lipka-Bartosik, Henrik Wilming, and Nelly H. Y. NgA branch of quantum information is concerned with transformations that are possible given certain resources: for example, quantum teleportation moves a quantum state from one place to another, aided by entanglement and classical communication. Certain other tasks are provably impossible....

Author(s): M. Cristina VolpeNeutrinos can change flavors due to their nonzero masses and mixings as well as their interactions with matter and other neutrinos. In dense astrophysical environments, such as core-collapse supernovae or neutron star mergers, the problem of neutrino flavor evolution becomes very complex. Connections to other domains such...

Author(s): Mohamadreza Fazel, Kristin S. Grussmayer, Boris Ferdman, Aleksandra Radenovic, Yoav Shechtman, Jörg Enderlein, and Steve PresséFor centuries, human fascination with the living world motivated the development of tools for visualizing life’s events at the spatiotemporal scales beyond our visual range. While all optical microscopes use light...

Author(s): Morten Amundsen, Jacob Linder, Jason W. A. Robinson, Igor Žutić, and Niladri BanerjeeIn many solids, the spin-orbit interaction is only a small effect. However, in certain materials it leads to new phenomena. This Colloquium reviews the role of spin-orbit interaction in superconducting hybrid structures, where it can lead to exotic states...

Author(s): Qijin Chen, Zhiqiang Wang, Rufus Boyack, Shuolong Yang, and K. LevinThe theory of unconventional superconductors continues to provide profound puzzles. The crossover between the weakly coupled Bardeen-Cooper-Schrieffer (BCS) state and the strong-pairing Bose-Einstein condensate (BEC) provides a useful perspective on how to address these questions....
