Some New Exact Ground States for Generalized Hubbard Models
A set of new exact ground states of the generalized Hubbard models in arbitrary dimensions with explicitly given parameter regions is presented. This is based on a simple method for constructing exact ground states for homogeneous quantum systems.

متن کاملExact Ground States of Generalized Hubbard Models.
We present a simple method for the construction of exact ground states of generalized Hubbard models in arbitrary dimensions. This method is used to derive rigorous criteria for the stability of various ground state types, like the η-pairing state, or Néel and ferromagnetic states. Although the approach presented here is much simpler than the ones commonly used, it yields better bounds for the ...
متن کاملExact many-electron ground states on the diamond Hubbard chain.
Exact ground states of interacting electrons on the diamond Hubbard chain in a magnetic field are constructed which exhibit a wide range of properties such as flat-band ferromagnetism and correlation-induced metallic, half-metallic, or insulating behavior. The properties of these ground states can be tuned by changing the magnetic flux, local potentials, or electron density.
متن کاملExact Ground States and Excited States of Net Spin Models
We study a set of exactly soluble net spin models. There exist two kinds of ground state, one is a complete dimerized state, and the other one is the ground state of corresponding spin-1 model. For the excitation gap, various phases were discovered and determined. PACS number: 75.10.-b, 75.10.Jm, 75.30.Kz Typeset using REVTEX 1 It is well known that a spin-1/2 antiferromagnetic chain with neare...
متن کاملExact spontaneous plaquette ground states for high-spin ladder models
We study the exchange physics in high-spin Mott insulating systems with S=3/2 which is realizable in ultracold atomic systems. The high symmetry of SO 5 or SU 4 therein renders stronger quantum fluctuations than the usual spin-1 /2 systems. A spontaneous plaquette ground state without any site and bond spin orders is rigorously proved in a ladder spin-3 /2 model, whose topological excitations e...
