Non-fermi-liquid-like Behavior in the Two-dimensional T − J Model
نویسنده
چکیده
The spin, charge and pairing correlation functions for the ground state of two-dimensional t − J model are calculated by using the power method which projects out the ground state from a variational wave function. “Exact” results are obtained for 10 × 10 and 8 × 8 lattices with low particle densities. The results are surprisingly similar to that of one-dimensional t − J model. The phenomenology is almost perfectly correlated with the concept of TomonagaLuttinger liquid and it is incompatible with traditional Fermi liquid theory.

In this paper a compact current-voltage model for MOSFET-like Carbon Nanotube Field Effect Transistors (MOSFET-like CNFET) is presented. To model these devices the one-dimensional drain/source current equation obtained from Landauer approach must be solved self-consistently with the equation relates the Fermi surface and carrier concentration. Also, numerically solve of the integral over densit...
متن کاملNon-Fermi Behavior of the Strongly Correlated Electron Systems
(1) The temperature dependence of the specific heat for a marginal Fermi liquid has been calculated . We showed that the expected T lnT correction is characteristic for the low temperature domain. The high temperature domain has a supplementary correction. The results are in agreement with the non-Fermi behavior of some metallic systems in the low temperature domain. (2) We calculated the self-...
متن کاملBosonization for 2D Interacting Fermion Systems: Non-Fermi Liquid Behavior
Non-Fermi liquid behavior is found for the first time in a two-dimensional (2D) system with non-singular interactions using Haldane’s bosonization scheme. The bosonized system is solved exactly by a generalized Bogoliubov transformation. The fermion momentum distribution, calculated using a generalized Mattis-Lieb technique, exhibits a non-universal power law in the vicinity of the Fermi surfac...

We calculate the exact Green function of a special model of N coupled Luttinger chains with arbitrary interchain hopping t⊥. The model is exactly solvable via bosonization if the interchain interaction does not fall off in the direction perpendicular to the chains. For any finite N we find Luttinger liquid behavior and explicitly calculate the anomalous dimension γ(N). However, the Luttinger li...

We point out the incorrect statement of the recent manuscript by K. Penc and B. S. Shastry. In a recent manuscript [1] K. Penc and B. S. Shastry wrote in the first paragraph: “Schulz and Shastry [2] have introduced a new class of gauge-coupled one-dimensional (1D) Fermi systems that are non Fermi liquid in the sense that the momentum distribution function has a cusp at the Fermi momentum kF rat...
