We explore intraparticle quantum resources within a monolayer \(\textrm{MoS}_2\) system subjected to thermal noise. Using a low-energy spin–valley effective Hamiltonian, we give the associated Gibbs density matrix and investigate the dynamics of concurrence ( \(\mathcal {C}\) ), local quantum uncertainty ( \(\mathcal {L}_q\) ), relative entropy of coherence ( \(\mathcal {C}_r\) ), and linear entropy ( \(\mathcal {L}_e\) ) as functions of temperature and the two-qubit system’s parameters. Our findings reveal that entanglement vanishes at all system regimes. In contrast, quantum correlations and coherence exhibit a slightly more robust persistence under thermal noise. For high momentum components ( \(k_x\) , \(k_y\) ) or weaker spin-orbit interaction (SOC, \(\lambda _s\) ), \(\mathcal {C}_r\) attains relevant values at lower temperatures before decreasing as T increases. We note that, although a strong SOC suppresses coherence, it extends the temperature interval over which LQU remains slightly significant, and it is also observed to decelerate the increase in \(\mathcal {L}_e\) . These findings show that adjusting system parameters enhances thermal quantum resources in the spin-valley state of \(\textrm{MoS}_2\) and mitigates thermal mixing.
