The canonical partition function in the model with heavy quarks in the system is derived. A mean field analysis of SU(2) gauge theory is carried out within this formulation. This analysis can contribute to an understanding of the role of the baryon number conservation in lattice QCD ...
In this work, we bridge this gap by numerically simulating, via TN ansatz states, an Abelian lattice gauge theory akin to (3 + 1) Quantum Electrodynamics (QED), at zero temperature. We show that, by using the quantum link formalism (QLM) of LGTs51,52 and an unconstrained Tree TN...
is the filled Fermi sea rather than the empty state. We regard the Fermi sea as our "physical vacuum" of the theory.Tight Binding Approximation In solids, it is a good approximation to consider only the ground state of electrons at room temperature since the groud state energy is far lower...

(2) gauge theory, such that the matrix representation of the former is diagonal in\mathcal {H}. This is achieved by discretising the sphereS_3isomorphic to SU(2) and the corresponding directional derivatives. We show that the fundamental commutation relations are fulfilled up to discretisation ...
Herein, using in-situ characterizations, we provide direct experimental evidence that the surface chemisorbed oxygen participated in the sensing process can come from lattice oxygen of the oxides. Further density functional theory (DFT) calculations prove that the p-band center of O serves as a ...
(Details in Appendix B.2 and B.2). During the photopolymers deposition, the previous layers are compacted by the upper resin layer. Moreover, they are subjected to subsequent rounds of UV curing at gradually less energy, since the UV light has to penetrate through an increasing number of ...
LBM have been used in the past to simulate a wide variety of fluid flow applications. They originated from the lattice gas automata which are discrete models for the simulation of transport phenomena [7]. In these models the computational grid consists of a number of lattice points that are ...
Random-walk theory and the decay of pair correlations in Ornstein-Zernike lattice systems 来自 EconPapers 喜欢 0 阅读量: 32 作者:A.,Robledo,and,I.E.,Farquhar 摘要: A random-walk formalism is applied to some general Ornstein-Zernike lattice systems to obtain information as to the asymptotic ...
In this paper, based on the lattice SF networks model, a linking weight is added, thus an additional parameter which can control the clustering coefficient is introduced. Depending on the linking weight, the properties of the model change smoothly from the lattice SF model to the SF random ...
