The numerical treatment of quantum systems often requires large amounts of computing power and time. As a result, performing calculations repeatedly for different values of the input parameters is often not feasible. One remedy is using eigenvectors describing the system that are analytic functions that vary smoothly for real values of the input parameters. This allows one to replace computationally expensive calculations with emulators that project onto a reduced-basis set. This Colloquium explores a particular class of reduced-basis methods known as eigenvector continuation and its applications, with emphasis on nuclear physics.

Vivien Zapf is a condensed matter experimentalist at the National High Magnetic Field Lab at Los Alamos National Lab where she has worked since 2004. She studies magnetic materials, in particular quantum magnetism and magnetoelectric coupling and specializes in thermodynamic and magnetoelectric measurements at low and high magnetic fields.

Rayleigh-Bénard convection is the flow in a closed box heated from below and cooled from above. The ultimate regime of Rayleigh-Bénard turbulence occurs when the dimensionless temperature difference between the bottom and top plates is large. This review gives a comprehensive overview of the theoretical approaches to the ultimate regime and of the experimental and numerical results on the transition to this regime. These are reconciled by realizing that the transition is of non-normal–nonlinear nature, as typical for the laminar to turbulent transition in shear flow. The review also suggests experimental and numerical approaches to further understand the transition to the ultimate regime.

Nelly Ng studies “quantum catalysts”—extra qubits or other elements that can help perform a quantum information process, in the same way that an extra tower helps solve a classic logic game.

Storage 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 benefit from quantum coherence and collective effects. This Colloquium reviews theoretical concepts and experimental implementations of energy storage in quantum batteries drawing on work in quantum thermodynamics and quantum information science.

A 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. But, as surveyed in this review, a surprising fact is that some tasks become possible if another quantum state is present, even if this state is returned untouched at the end of the task. This “quantum catalysis” enables a large variety of interesting tasks, with applications ranging from cryptography to thermodynamics.

While the first law of thermodynamics is a well-established principle underlying all models of Earth’s climate system, applications of the second law in climate science are active areas of research. This review summarizes how the relationships between Earth’s entropy export and internal entropy production provide insights into Earth’s climate. These applications include heat-engine analogs for atmospheric convection, tropical cyclones, and large-scale atmospheric heat transport. Open issues addressed include the ongoing debate on whether the climate system maximizes entropy production.
