Abstract
En 中文
Dissipative adaptation is a general thermodynamic mechanism that explains self-organization in a broad class of driven classical many-body systems. It establishes how the most likely (adapted) states of a system subjected to a given drive tend to be those following trajectories of highest work absorption, followed by dissipated heat to the reservoir. Here, we extend the dissipative adaptation phenomenon to the quantum realm. We employ a fully-quantized exactly solvable model, where the source of work on a three-level system is a single-photon pulse added to a zero-temperature infinite environment, a scenario that cannot be treated by the classical framework. We find a set of equalities relating adaptation likelihood, absorbed work, heat dissipation and variation of the informational entropy of the environment. Our proof of principle provides the starting point towards a quantum thermodynamics of driven self-organization. Dissipative adaptation is a general thermodynamic mechanism that explains self-organization in classical systems via dissipation of absorbed work, revealing a principle of life-like behaviour. Here, the authors show that dissipative adaptation remains valid in a fully-quantum zero-temperature model, providing the starting point towards a quantum thermodynamics of driven self-organization
