A Feynman graph method is developed to evaluate the energy 〈φHe s He s Hφ〉/ 〈φHe 2 s Hφ〉 expectation value of a Jastrow wave function of a fermion system. The method is valid in the case where S is a general (non-local) two-body operator. It is shown that when S is ...
Displacement - time graphs for two waves, wave - 1 and wave - 2 are shown here. The ratio of the intensity of wave-1 to that of wave - 2 is

This can be seen for instance (formally, at least) by inspecting the exterior energy and observing (after some integration by parts and differentiation under the integral sign) that it is non-increasing in time, non-negative, and vanishing at time . The wave equation is second order in ...
In this paper, we study the schrodinger equation and wave equation with the Dirichlet boundary condition on a connected finite graph. The explicit expressions for solutions are given and the energy conservations are derived. Applications to the corresponding nonlinear problems are indicated....

Indeed, the following scalar product (also called Dirichlet energy)(6)(f,Lf)=f⊤Lf=∑(i,j)∈EAij(f(j)−f(i))2=‖∇f‖22 computes the sum of the variations of a graph signal f, where Aij is the weight of the link (i,j). Hence, for each graph Fourier mode uk, the (...
We construct two types of multi-layer quantum graphs (Schrödinger operators on metric graphs) for which the dispersion function of wave vector and energy is proved to be a polynomial in the dispersion function of the single layer. This leads to the reducibility of the algebraic Fermi surface,...
