摘要翻译:
研究了自旋1/2粒子与线性振子相互作用的超立方D维晶格的量子模型,证明了该模型具有三个铁磁基态序参量。两个序参量在第一和第三方向上与磁化强度一致,第三个序参量是连续振子变量中的磁化强度。证明采用了一个广义的Peierls论元和两个Griffiths不等式。自旋振子哈密顿类在基态中表现出极大的有序性。该模型对氢键铁电体具有相关性。其中最简单的被证明有一个独特的吉卜赛基态。

英文摘要:
  Quantum models on the hyper-cubic d-dimensional lattice of spin-1/2 particles interacting with linear oscillators are shown to have three ferromagnetic ground state order parameters. Two order parameters coincide with the magnetization in the first and third directions and the third one is a magnetization in a continuous oscillator variable. The proofs use a generalized Peierls argument and two Griffiths inequalities. The class of spin-oscillator Hamiltonians considered manifest maximal ordering in their ground states. The models have relevance for hydrogen-bond ferroelectrics. The simplest of these is proven to have a unique Gibbsian ground state.
