In a previous paper[***.A95,060701(R)(2017)],we demonstrated that a new type of two-body interaction,which depends on the center of mass(CoM)momentum,can be realized for ultracold atoms via laser-modulated magnetic Feshbach resonance(MFR).Further studies(e.g.L He et al,***.120,045302(2018))show that various interesting phenomena,such as Fulde–Ferrell superfluids,can be induced by scattering between ultracold atoms with this *** this work we investigate the shallow bound states of two ultracold atoms with this type of *** show that when the magnetic field B is below the MFR point B0,two shallow bound states can appear in this ***,a'two-component dimer'or a dimer with pseudo-spin 1/2 can be formed by two ***,the dispersion curve of the dimer may have either single or double minimums in the CoM momentum *** latter case can be explained as a result from significant pseudo-spin-orbital coupling(SOC)*** results show that the ultracold gases with CoM momentum dependent interaction may be a candidate for quantum simulations with ultracold two-component molecules,especially the molecule gases with SOC.

当代新儒家是继先秦儒学与宋明理学而起的第三波,其主要任务是对强势的近代西方哲学挑战的回应。五四运动倡全盘西化,引致新儒家之反弹。张君劢挑起科玄学论战,对西方哲学的理解与批评既不周延也不称理。第二代新儒家唐君毅、牟宗三起于抗战,精神上虽承继第一代的熊十力在"量智"之外挺立"性智",在表述上却由西方哲学如康德、黑格尔转手。迥异时流之无体、无理、无力,由内在体证超越,挺立道德主体与认识主体。1958年元旦,4位流亡港、台、海外的学者:唐君毅、牟宗三、徐复观、张君劢签署《中国文化与世界宣言》,坚持"道统"维护传统的精神价值以供奉于世界,开拓"学统"与"政统"以吸纳西方的科学与民主。第三代新儒家刘述先、杜维明更与时推移,唤醒全球意识,通贯古今中外,体现"理一而分殊",存异求同,多元互济,才能对人类与地球的永续寄予无穷的希望。

当前流行全球在地化思想。表面上看,全球化的趋势与在地化的趋势是对立的两极,其实不然。二者相辅相成,必须通过在地的传统,超越现有国家、民族、宗教的籓篱,开拓全球意识。我要做的即是通过当代新儒家的视域对全球在地化问题作出反思与响应。文章首先撮述儒家精神传统的核心概念与价值,但重点并不在此,而在针对当代西方学者的反思作出响应。正好有基督宗教背景的香港学者关启文撰文介绍马莎·纽斯邦(Martha Nussbaum)于1994年发表"Patriotism and Cosmopolitanism"一文重启爱国主义与普世主义的争端,引起当代西方精英学者16篇响应文章,然后有纽斯邦的回答。我利用关教授的撮述、批判、综合、探索引发思路,并由我自己一贯的新儒家观点吸纳新的睿识,作出反思与回应。

朱子与儒家的精神传统

儒家哲学可分为三个大时代:先秦、宋明、现代;儒家的精神传统,不只是俗世伦理;先秦儒学最关键性的人物是孔子(仁内礼外)和孟子(仁义内在、性由心显);二程担负道统,对性理进行了阐发和开拓,朱子建构道统,编纂了《近思录》和《四书集注》... 详细信息

儒家哲学可分为三个大时代:先秦、宋明、现代;儒家的精神传统,不只是俗世伦理;先秦儒学最关键性的人物是孔子(仁内礼外)和孟子(仁义内在、性由心显);二程担负道统,对性理进行了阐发和开拓,朱子建构道统,编纂了《近思录》和《四书集注》,程朱学被定为圣学的一支。五四(1919)反传统,儒学由中心到边缘,当代新儒家对儒学进行了积极的反思,儒学复兴。进入新世纪,儒家学者应该给予"理一分殊"以创造性的诠释以面对"全球地域化"的挑战。
