Key Points

  • This research aims to explore the relationship between energy dissipation and self-organization in a quantum driven open system.
  • Employs a system-reservoir approach using a time-dependent spin-boson Hamiltonian.
  • Analyzes quantum dynamics of a particle in a metastable double-well potential with controlled asymmetry.
  • Examines transition probabilities between ground states influenced by external drive.
  • Demonstrates how energy dissipation influences self-organization in quantum regimes.
  • Finds that work from the dynamic potential relates to the likelihood of state transitions.
  • Highlights the thermodynamic implications of the driven spin-boson model.

Abstract

Abstract We investigate the dissipative adaptation hypothesis in a quantum regime using a system-reservoir approach. This hypothesis proposes that self-organization arises from a system’s ability to dissipate the work transiently absorbed from an external drive. We analyze the quantum dynamics of a driven open system described by a time-dependent spin-boson Hamiltonian modeling a particle in a metastable double-well potential with controllable asymmetry. We explore how the work provided by the dynamic potential is related to the transition probability between the two ground states of the double well. These studies motivate further investigations of the driven spin-boson model toward an understanding of the system’s evolution and its thermodynamic implications.
