Hubbard model with boundary fields
A supersymmetric U q [osp(2|2)]-extended Hubbard model with boundary fields Abstract A strongly correlated electron system associated with the quantum superalgebra U q [osp(2|2)] is studied in the framework of the quantum inverse scattering method. By solving the graded reflection equation, two classes of boundary-reflection K-matrices leading to four kinds of possible boundary interaction term...
متن کاملIntegrable Boundary Conditions for the One-Dimensional Hubbard Model
We discuss the integrable boundary conditions for the one-dimensional (1D) Hubbard Model in the framework of the Quantum Inverse Scattering Method (QISM). We use the fermionic R-matrix proposed by Olmedilla et al. to treat the twisted periodic boundary condition and the open boundary condition. We determine the most general form of the integrable twisted periodic boundary condition by consideri...
متن کاملExact solutions of 1-D Hubbard model with open boundary conditions and the conformal dimensions under boundary magnetic fields
The Bethe ansatz equations of the 1-D Hubbard model under open boundaryconditions are systematically derived by diagonalizing the inhomogeneous trans-fer matrix of the XXX model with open boundaries. Through the finite-sizecorrection, we obtain the energy spectrum of the open chain and discuss the ef-fects of boundary magnetic fields applied only at the edges of the chain. S...

We apply recently developed smooth boundary conditions to the quantum Monte Carlo simulation of the two-dimensional Hubbard model. At half-filling, where there is no sign problem, we show that the thermodynamic limit is reached more rapidly with smooth rather than with periodic or open boundary conditions. Away from half-filling, where ordinarily the simulation cannot be carried out at low temp...
متن کاملIntegral Equation Methods for Solving Laplace's Equation with Nonlinear Boundary Conditions: the Smooth Boundary Case
A nonlinear boundary value problem for Laplace's equation is solved numerically by using a reformulation as a nonlinear boundary integral equation. Two numerical methods are proposed and analyzed for discretizing the integral equation, both using product integration to approximate the singular integrals in the equation. The first method uses the product Simpson's rule, and the second is based o...
