狄拉克半金属中的Efimov效应 早在 1970 年， Vitaly Efimov 教授研究接触相互作用的全同波色子的三体问题时发现体系有无穷多个奇异的三体束缚态 ，这些束缚态的能量满足等比级数的关系 E n = E 0 exp(-2π n / s 0 ) 。这一现象之后被称为 Efimov 效 ...
Cover Since the discovery of graphene in 2004, many other 2D materials with unique properties and promising applications have been developed, which directly resulted in this special topic. Besides experimental investigations, computational/theoretical studies also played an important ro ...
Cover The search for and study of exotic quantum states in novel low-dimensional quantum materials havetriggered extensive research in recent years. In our recent paper, we proposed that the realization of ferromagnetism in the newly discovered two-dimensional quantum material C 3 N ...
Cover The special topic edited by F. Mallamace, R. Car Limei Xu reports eleven contributions jointly written by lecturers and students attending the 2016 “Ettore Majorana” Erice International School on Water and Water Systems. These papers focus on the study of water and its so ...
Cover As a universal concept in nonlinear science, synchronization has been broadly interested and extensively studied over the past decades. Whereas numerical and theoretical studies have unveiled abundant synchronization phenomena in coupled oscillators, few of them have been repl ...
