This is a software implementation in C/C++ that focuses on the thermalization process and the Crooks fluctuation theorem for work. The implementation specifically considers the interaction of a Brownian particle with a bath that is both finite and chaotic.

QO_poinc.cpp
- Poincarè sections for a quartic oscillator. Hamiltonian dynamics is performed by applying fourth-order symplectic integration, this published by Ref.[1].
-
N_chaotic_baths.cpp
- System relaxation in contact to a finite and chaotic heat bath. The latter modeled by a quartic oscillator. Hamiltonian dynamics is performed by applying fourth-order symplectic integration, this published by Ref.[1].
-
Forward_FT.cpp
- Forward protocol is done in a system coupled to a finite and chaotic heat bath. The latter modeled by a quartic oscillator. Hamiltonian dynamics is performed by applying fourth-order symplectic integration, this published by Ref.[1].
-
Reverse_FT.cpp
- Reverse protocol is done in a system coupled to a finite and chaotic heat bath. The latter modeled by a quartic oscillator. Hamiltonian dynamics is performed by applying fourth-order symplectic integration, this published by Ref.[1].
