本次更新为笔记的第五部分:Hubbard模型中的Bose-Hubbard Model。 Hubbard Model中根据其on-site repulsion U, hopping intensity J & chemical potential μ 的不同,会给出丰富的不同于经典相的exotic quantum phase,例如Mott Insulator (MI)态、Superfluidity (SF)态、Antiferromagnetic spin order (AFM)等 本章...
interactionsWe employ the (dynamical) density matrix renormalization group technique to investigate the ground-state properties of the Bose-Hubbard model with nearest-neighbor transfer amplitudes t and local two-body and three-body Coulomb repulsion of strength U and W, respectively. We determine the ...
5. 关联函数 二、一些Bose-Hubbard模型的解析理论 考虑Hubbard Model在超流-Mott绝缘体相变点附近的行为。在Mott绝缘体一侧,每个site上有恒定粒子数n。如果稍加微扰,可以认为在第i个site上的粒子可以用|n-1\rangle,|n\rangle,|n+1\rangle展开。而这实际上很类似我们处理的对spin-1的粒子的三个基:|J_z=1,0...
在Hubbard Model中，根据on-site repulsion U、hopping intensity J和chemical potential[公式]的不同，会出现多种不同于经典相的exotic quantum phase，如Mott Insulator (MI)态、Superfluidity (SF)态和Antiferromagnetic spin order (AFM)态等。本章主要涵盖Bose-Hubbard Model (BHM)的哈密顿量、两种极...

Bose-Hubbard模型 1. The Bose-Hubbard model is a basic model which contains main features in the strongly interacting Bose systems. 本文研究的是不存在无规势时的一维Bose-Hubbard模型,本模型中仅考虑了玻色子最邻近格点间跳迁,而同一格点上玻色子相互排斥作用强度不依赖于格点,且为一维环状晶格或格点周期...
Route to supersolidity for the extended Bose-Hubbard modelWe use the Gutzwiller ansatz and analyze the phase diagram of the extended Bose-Hubbard Hamiltonian with on-site (U) and nearest-neighbor (V) repulsions. For d-dimensional hypercubic lattices, when 2dVU, in this Rapid Communication, we...
