AbstractAbstract
[en] Violation of Leggett-Garg inequalities can serve as a signature of a failure of (macroscopic) realism. We investigate violation of the simplest Leggett-Garg inequality for a qubit coupled to an integer j spin (angular momentum). Such a system effectively reveals quantum-classical hybrid behavior in the limit of large j values. We show that a maximal violation of the Leggett- Garg inequality is larger for quantum-classical hybrids than for fully quantum systems. (paper)
