contents In this article, we explore Higgs bundles on a projective manifold $X$, focusing on their spectral bases, a concept introduced by T.Chen and B.Ngô. The spectral base is a specific closed subscheme within the space of symmetric differentials. We observe that if the spectral base vanishes, then any reductive representation $ρ: π_1(X) \to \text{GL}_r(\mathbb{C})$ is both rigid and integral. Additionally, we prove that for $X=Ω/Γ$, a quotient of a bounded symmetric domain $Ω$ of rank at least $2$ by a torsion-free cocompact irreducible lattice $Γ$, the spectral base indeed vanishes, which generalizes a result of B.Klingler.
