Universal structure of objective states in all fundamental causal theories

چکیده
A crucial question is how objective and classical behavior arises from a fundamental physical theory. Here we provide natural definition of decoherence process valid in all causal theories, show its can be extremely different the quantum one. Remarkably, despite this, prove that so-called spectrum broadcast structure characterizes states every theory, exactly as mechanics. Our results stark contrast between extraordinarily diverse universal features objectivity.

Thermodynamic depth of causal states: Objective complexity via minimal representations
Thermodynamic depth is an appealing but flawed structural complexity measure. It depends on a set of macroscopic states for a system, but neither its original introduction by Lloyd and Pagels nor any follow-up work has considered how to select these states. Depth, therefore, is at root arbitrary. Computational mechanics, an alternative approach to structural complexity, provides a definition fo...

متن کاملNonmonotonic causal theories
The nonmonotonic causal logic defined in this paper can be used to represent properties of actions, including actions with conditional and indirect effects, nondeterministic actions, and concurrently executed actions. It has been applied to several challenge problems in the theory of commonsense knowledge. We study the relationship between this formalism and other work on nonmonotonic reasoning...
