Multiplons in the two-hole excitation spectra of the one-dimensional Hubbard model

Using the density-matrix renormalization group in combination with the Chebyshev polynomial expansion technique, we study the two-hole excitation spectrum of the one-dimensional Hubbard model in the entire filling range from the completely occupied band ( n = 2) down to half-filling ( n = 1). For st...
