摘要翻译：
本文提出了一维、二维和三维四次势中有限格中非相互作用玻色子的玻色凝聚的理论研究。我们研究了维数效应和四次势对单玻色子能态密度、凝聚温度、凝聚分数和比热的影响。将所得结果与谐波陷阱中晶格玻色子的相应结果进行了比较。

英文摘要：
  We present a theoretical study of bose condensation of non-interacting bosons in finite lattices in quartic potentials in one, two, and three dimensions. We investigate dimensionality effects and quartic potential effects on single boson density of energy states, condensation temperature, condensate fraction, and specific heat. The results obtained are compared with corresponding results for lattice bosons in harmonic traps.
