Critical Properties of One-Dimensional Electron Systems with -type Long-Range Interactions
Yasumasa Tsukamoto, Norio Kawakami
We study the critical properties of one-dimensional electron systems with the -type long-range interaction (). Using bosonization methods, we discuss how the 1D syst…

Critical Properties in Photoemmision Spectra for One Dimensional Orbitally Degenerate Mott Insulator
T. Fujii, Y. Tsukamoto, N. Kawakami
Critical properties in photoemission spectra for the one-dimensional Mott insulator with orbital degeneracy are studied by exploiting the integrable {\it t-J} model, which is a sup…

Critical Properties of Spectral Functions for the 1D Anisotropic t-J Models with an Energy Gap
T. Fujii, Y. Tsukamoto, N. Kawakami
We exactly calculate the momentum-dependent critical exponents for spectral functions in the one-dimensional anisotropic t-J models with a gap either in the spin or charge excitati…
