According to the author's model, the bound states of dopant ions and hole orbitals in lightly doped cuprates can be treated as pseudoatoms. Their alignment leads to formation of extended quantum protectorates - bosonic stripes (BS) characterized by a set of discrete widths. The simulations of electronic properties performed for La_2CuO_(4+δ), YBa_2Cu_3O_(6+δ), and HgBa_2Ca_2Cu_3O_(8+δ) in the framework of this scenario are consistent with experimental data. It is argued that the concept of BS hierarchy may help not only to clarify the heart of unconventional physics of cuprates but also to answer the crucial questions about perspectives to raise the superconducting critical temperature above 300 K. 收起
