Constructing Two-Dimensional Multi-Wavelet for Solving Two-Dimensional Fredholm Integral Equations
In this paper, a two-dimensional multi-wavelet is constructed in terms of Chebyshev polynomials. The constructed multi-wavelet is an orthonormal basis for space. By discretizing two-dimensional Fredholm integral equation reduce to a algebraic system. The obtained system is solved by the Galerkin method in the subspace of by using two-dimensional multi-wavelet bases. Because the bases of subs...
متن کاملTwo-dimensional bosonization from variable shifts in the path integral∗
A method to perform bosonization of a fermionic theory in (1 + 1) dimensions in a path integral framework is developed. The method relies exclusively on the path integral property of allowing variable shifts, and does not depend on the explicit form of Greens functions. Two examples, the Schwinger model and the massless Thirring model, are worked out. PACS numbers: 11.10.Kk; 11.15.Tk
متن کاملPath-integral calculation of the two-dimensional He phase diagram
Path-integral Monte Carlo simulations have been used to determine the phase diagram of a two-dimensional He film in a range of temperatures and coverages where it undergoes solidification, superfluidity, and a liquid-gas transition (0.25 K<T<1.5 K 0,s,0.094 Å). We determine the phase-transition densities and give the coefficients for a functional form of the free energy in the liquid, solid, an...
متن کاملOne-dimensional SU(3) bosons with δ-function interaction
Abstract In this paper, we solve one-dimensional SU(3) bosons with repulsive δ-function interaction using the Bethe ansatz method. The features of the ground and low-lying excited states are studied by both numerical and analytical methods. We show that the ground state is a SU(3) colour ferromagnetic state. The configurations of quantum numbers for the ground state are given explicitly. For a ...
متن کاملTwo-dimensional H2 clusters: A path-integral Monte Carlo study
The possibility of maintaining H2 in a fluid state at temperatures low enough to produce a superfluid has recently attracted considerable attention. Unfortunately, the H2-H2 interaction is too strong to allow molecular hydrogen to be a liquid below its bulk triple point of 14 K. One way to attain a liquid ground state is to reduce the effective attraction between the H2 molecule or alternativel...
