TC/TCL and NETFD Correspondence Principles for Information Backflow: A Structural Monotonicity Theorem and Minimal Phase Diagrams (opens in new tab)

arXiv:2602.09054v1 Announce Type: cross Abstract: We propose a unified structural framework for information backflow in minimal non-Markovian relaxation processes. The central idea is to interpret non-Markovianity as an embedding phenomenon in which observable degrees of freedom exchange information with hidden auxiliary sectors. Our approach is based on two standard formalisms in nonequilibrium physics: (i) the time-convolution (TC) and time-convolutionless (TCL) projection-operator master ...
