In scenarios coined Maxwell's demon, information on microscopic degrees of freedom is used to seemingly violate the second law of thermodynamics. This has been studied in the classical as well as the quantum domain. In this paper, we study an impleme

A quantum impulse is a brief but strong perturbation that produces a sudden change in a wave function ψ(x). We develop a theory of quantum impulses, distinguishing between ordinary and super impulses. An ordinary impulse paints a phase onto ψ, whil

Quantum energy coherences represent a thermodynamic resource, which can be exploited to extract energy from a thermal reservoir and deliver that energy as work. We argue that there exists a closely analogous classical thermodynamic resource, namely,

When a chaotic, ergodic Hamiltonian system with N degrees of freedom is subject to sufficiently rapid periodic driving, its energy evolves diffusively. We derive a Fokker-Planck equation that governs the evolution of the system's probability distribu

In fast-forward quantum shortcuts to adiabaticity, a designed potential U_{FF}(q,t) steers a wave function to evolve from the nth eigenstate of an initial Hamiltonian H[over ̂](0) to the nth eigenstate of a final Hamiltonian H[over ̂](τ), in finit

Self-oscillation is a phenomenon studied across many scientific disciplines, including the engineering of efficient heat engines and electric generators. We investigate the single electron shuttle, a model nano-scale system that exhibits a spontaneou

We introduce and investigate a simple and explicitly mechanical model of Maxwell’s demon—a device that interacts with a memory register (a stream of bits), a thermal reservoir (an ideal gas) and a work reservoir (a mass that can be lifted or lowe

Feynman’s ratchet is a microscopic machine in contact with two heat reservoirs, at temperatures T _A and T _B , that was proposed by Richard Feynman to illustrate the second law of thermodynamics. In equilibrium ( T _A = T _B ), thermal fluctuation

Although nonequilibrium work and fluctuation relations have been studied in detail within classical statistical physics, extending these results to open quantum systems has proven to be conceptually difficult. For systems that undergo decoherence but

A shortcut to adiabaticity is a recipe for generating adiabatic evolution at an arbitrary pace. Shortcuts have been developed for quantum, classical and (most recently) stochastic dynamics. A shortcut might involve a counterdiabatic (CD) Hamiltonian
