Symmetries, Conservation and Dissipation in Time‐Dependent Contact Systems

J Gaset, A López‐Gordón, X Rivas - Fortschritte der Physik, 2023 - Wiley Online Library
In contact Hamiltonian systems, the so‐called dissipated quantities are akin to conserved
quantities in classical Hamiltonian systems. In this article, a Noether's theorem for non …
