摘要:凝聚态物理是对称性破缺的产物,由此讨论Ising模型及其推广;探讨分形的应用和Hall效应;探索宏观量子效应和超流;探讨高温超导及其袋模型,联系于玻色-爱因斯坦凝聚(BEC),预言应该存在高温超流;讨论粒子-分子的类似性等,并总结宏观量子效应.

关键词: 凝聚态物理, 宏观量子效应, 分形, Hall效应, 超流, 高温超导, 玻色-爱因斯坦凝聚

Abstract: All condensed state physics is the result of breaking symmetry.Ising model and its extension are thus discussed.Then the fractal applications and Hall effect are researched.Thirdly,the macroscopic quantum effects and superfluidity are explored.Fourthly,the high-Tc superconductivity is discussed,and its bag model is investigated.These are related with the Bose-Einstein condensation(BEC),and the author predicts that the high-Tc superfluidity should exist.Finally,the similarity between particles and molecules is discussed,and the macroscopic quantum effects are summarized.

Key words: condensed state physics, macroscopic quantum effect, fractal, Hall effect, superfluidity, high-Tc superconductivity, BEC
