The controlled stacking, twisting, and straining of two-dimensional van der Waals materials has opened new avenues for realizing correlated and topological quantum phases. In such heterostructures, interactions between layers can give rise to emergent properties not present in the individual constituents, including correlated metals, heavy fermion behavior, exotic magnetism, and unconventional superconductivity. In this talk, I will concentrate on multilayered 1T/1H TaS₂, 4Hb-TaS2 and discuss results regarding their electronic, magnetic and superconducting properties [1-3] with connections to recent experimental findings.
