Designing one-dimensional well-isolated flat bands in untwisted bilayer black phosphorus by asymmetric uniaxial strain

One-dimensional (1D) flat bands in low-dimensional materials enable the study of exotic correlated phases like bond density waves, Luttinger liquids, and Mott insulators. However, the underlying mechanisms driving their formation remain elusive, and achieving well-isolated 1D flat bands in readily a...
