Coherence and Non-classical Correlations within a Graphene Layer System Subjected to Intrinsic Decoherence
摘要
This study explores the dynamic evolution of non-classical correlations and coherence within a two-dimensional graphene layer, examining its vulnerability to intrinsic decoherence. We use local quantum uncertainty (LQU) to quantify the level of quantum correlations, while assessing quantum coherence using the \(l_1\) -norm ( \(C_{l_1}\) ) and relative entropy of coherence ( \(C_r\) ). We investigate how these quantum estimators respond to various parameters of the graphene system, including wavenumber operators, the initial-state mixing parameter, and intrinsic decoherence factor. Our results demonstrate that adjusting the wavenumber operators, increasing the purity parameter, and reducing the intrinsic decoherence rate can enhance both quantum coherence and correlations in the graphene layer system. Furthermore, we observe that \(C_{l_1}\) and \(C_{r}\) exhibit greater resilience to intrinsic decoherence compared to LQU.
