好久没更新_(:3」∠)_ 这次专栏文章展示二维零场 Ising model 的严格解,主要遵循Kaufman在1949年相关文章中的逻辑,他对Onsager的解法做出了简化。我们首先将计算 配分函数的问题转化为对角化转移矩阵的问题,把…
We propose a statistical mechanics approach to a coevolving spin system with adaptive network of interactions.The dynamics of nodes' states and network connections is driven by both spin configuration and network topology.We consider a hamiltonian that merges the classical Ising model and the ...
The Ising model is a fundamental concept in statistical mechanics, serving as a key tool for studying critical phenomena and developing techniques that have broader applications in various scientific problems. AI generated definition based on: Physics Reports, 2001 ...
The Ising Model, Statistical Mechanics and Mean Field Theory The first method to work out the equation Using the cross point to work out the equation Here is the two side of equation under various tempreture. It can be derived from the picture that Tc=4 is the critical temperature which de...
which cannot be exhibited classically. To decribe the behavior of a magnetic material, we should introduce the electron's spin and the associated magnetic moment in quantum mechanics. The Ising model is a mathematical model of ferromagnetism in statistical mechanics. In Ising Model,...
STATISTICAL MECHANICS OF 3-DIMENSIONAL FINITE ISING MODEL A model in statistical mechanics, characterised by a Gibbs measure, inherits a natural parameter-space geometry through an embedding into the space of squa... S Ono,Y Karaki,M Suzuki,... 被引量: 5发表: 1967年 ...
We study a Hamiltonian system describing a three-spin-1/2 cluster-like interaction competing with an Ising-like anti-ferromagnetic interaction. We compute free energy, spin correlation functions and entanglement both in the ground and in thermal states. The model undergoes a quantum phase transition...
The Ising model is a mathematical model of ferromagnetism in statistical mechanics. The model consists of discrete variables called spins that can be in one of two states. The spins are arranged in a lattice or graph, and each spin interacts only with its nearest neighbors. The goal is to ...
伊辛模型(Ising Model) 哎呀,又是好久没更新了。最近看了一下伊辛模型 (Ising model),感觉非常的有趣。 先来一段维基百科凑凑字数: 伊辛模型,是一个以物理学家恩斯特·伊辛为名的数学模型,用于描述物质的铁磁性。该模型中包含了可以用来描述单个原子磁矩的参数σi∈{−1,+1},分别代表自旋向上或向下,这些...
