20.500.12556/DiRROS-24448 Iterative construction of conserved quantities in dissipative nearly integrable systems Integrable systems offer rare examples of solvable many-body problems in the quantum world. Because of the fine-tuned structure, their realization in nature and experiment is never completely accurate, and therefore effects of integrability are observed only transiently. One way to overcome this limitation is to weakly couple nearly integrable systems to baths and driving: this will stabilize integrable effects up to arbitrary time and encode them in the stationary state approximated by a generalized Gibbs ensemble. However, the description of such driven dissipative nearly integrable models is challenging and no exact analytical methods have been proposed so far. Here, we develop an iterative scheme in which integrability breaking perturbations (baths) determine the conserved quantities that play the leading role in a highly efficient truncated generalized Gibbs ensemble description. Our scheme paves the way for easier calculations in thermodynamically large systems and can be used to construct unknown conserved quantities. fizika kvantna fizika kvantni sistemi true false true American Physical Society ZDA Angleški jezik Slovenski jezik © 2024 American Physical Society Neznano 2025-11-28 11:49:38 2025-11-28 11:49:39 2025-11-29 03:56:27 0000-00-00 00:00:00 2024 0 0 7 str.
