主要学术成绩:
在国际学术会议报告多次、在青年科学家论坛等全国性学术会议报告多次。以国际一学术流刊物为主,发表论文一百一十余篇,其中多篇论文引起国内外同行关注或被多次引用,有些研究成果在学术专著和《Science》上的综述文章中有专门介绍。
量子介观电路理论:提出电荷离散的介观电路量子理论并给出电荷-电流测不准关系和最小测不准波包。推出LC回路的Mathieu方程。用纯L回路观点导出介观环上持续流的公式。用纯C回路解释了库仑阻塞。发现耦合介观电路中有非对易几何结构。
轨道简并关联系统:提出轨道简并自旋系统的SU(4)理论,研究了自旋系统在有轨道自由度时的对称性及物理特性。指出在许多二维格点上,基态不具有长程序,这将有助于解释在LiNiO2中观察到的自旋液体特性。对一维模型用非微扰方法研究了基态和低激发态特性。解出准粒子色散关系和激发谱,并描绘了相应的直观图象。揭示了二重简并电子系统的基础对称性和隐藏的电荷对称性。证明在半满时等价与SO(6) 海森堡模型,在1/4填充时等价与SU(4) 海森堡模型。分析了由各向异性耦合及外场引起的各种可能的对称破缺。解出一维激发态准粒子色散关系。把关于自旋1/2的海森堡模型的LSM定理成功推广到与其它凝聚态模型有关的高阶对称群的情形。引入了3个Landè g因子,并系统地讨论了各种对称破缺。用LSM方法研究了4分量的Hubbard-like模型中基态和激发态的性质,严格地证明了该模型中基态是非简并的,而激发态的所有能带填充是无能隙的。
量子有序现象及其表征: 运用t-J模型研究了铜氧化物超导体中共振共价态电荷序问题。用重整化平均场理论估算电荷序存在时的能量。长程库仑作用势使电荷趋向密度分布不均匀导致稳定的电荷序共振共价态可以存在。讨论了它和近期铜氧化物高温超导体遂穿电导实验中观察到的4×4棋盘格子的可能联系。 在量子纠缠以及量子相变方面, 我们研究了扩展Hubbard模型中的局域纠缠问题。结果表明,在相变发生的临界点,局域纠缠达到最大或者出现奇异性。对于传统的Hubbard模型,临界点的标度行为表明局域纠缠是U的解析函数。我们还研究了局域纠缠对填充因子的依赖性。当填充因子为2/3或者1时,局域纠缠最大。在强耦合极限下,1/3填充具有最大局域纠缠,这表明具有最大对称性的基态拥有最大局域纠缠。这项工作第一次显示了纠缠能被用于确定费米子系统中的量子相变。通过应用李代数An的基本表示,提出了concurrence向量,以此提供一个清晰的判据来评价任意维双系统的纠缠。研究了concurrence C与SUq(2)代数的关系,XXZ模型在零K时的量子相变和关联长度ξ的依赖性. 结果表明,在临界点附近有C=C0-ξ/2。对不同尺度的系统,有一个关于关联长度ξ的普适标度函数C。研究了双qutrit系统的纠缠,如Lipkin-Meshkov-Glick模型等。氢原子中精细相互作用下外层电子和原子核间的热力学纠缠以及冷锂原子气中电子和核之间的纠缠,锂原子在超精细相互作用下的基态纠缠和热纠缠。
自旋电子学理论基础:我们给出了SU(2)×U(1)规范理论下统一的自旋与电荷流的定义式。在自旋轨道耦合下,自旋流并不守恒,而是在协变形式下满足流守恒方程。同时,轨道自旋流在电磁场中也不守恒。我们还得到了由SU(2)规范场提供的与自旋相关的力。 对于自旋输运中的的线性响应问题,我们研究了对非阿贝尔场的Kubo公式。结果表明,SU(2)流的不守恒部分保证了两种不同规范下的自恰性。在具有平方色散关系的系统中,对于SU(2)外场响应的自旋流为零。我们得出的Kubo公式可以推广到高自旋表示,如应用于研究双层自旋霍尔效应以及Luttinger 模型中的自旋霍尔效应。 应用Schwinger-boson平均场方法,我们研究了各项异性自旋环中由SU(2)磁通诱导的持续自旋流问题。各项异性有助于增强持续自旋流。对于二维电子系统中自旋霍尔电导在杂质存在下是否为零的争论,我们研究了磁性杂质下的自旋霍尔电导。应用Kubo线性响应理论并考虑顶角修正,我们发现自旋霍尔电导不为零,并且依赖于动量弛豫时间、自旋轨道劈裂和各项异性系数。在净极限下,自旋霍尔电导的取值范围为e/8–e/6。此外,我们还研究了准一维气体模型中不同程度的混沌对热载流子扩散及热传导行为的影响。数值计算验证了导热系数和扩散系数的指数之间满足一定的关系。并讨论了不同程度的混沌时温度曲线受有限尺度效应的影响。
玻色系统的量子效应:
随着玻色-爱因斯坦凝聚研究的蓬勃发展,我们对有δ函数形式排斥作用的一维多分量玻色系统展开了深入研究。用Bethe-ansatz和量子反散射方法,考虑SU(2)内部自由度的情况,首次发现二分量玻色子系统的基态为赝自旋铁磁态,并确定激发态有三类准粒子。求出二分量玻色格点模型的强耦合等效模型为铁磁Heisenberg 模型并给出其自旋波激发形式;提出二分量玻色系统的铁磁基态可完全来源于动力学驱动。进一步研究了SU(3)玻色子模型,玻色及玻色-费米混合模型的基态和激发态的特点。我们把自旋1/2 bond operators推广到自旋s≥1的情况。用Lieb-Schultz- Mattis方法研究了4分量的Hubbard-like模型中基态和激发态的性质,严格地证明了该模型中基态是非简并的,而激发态的所有能带填充是无能隙的。 我们研究了非简谐势中快速旋转的BEC中一些与涡旋态有关的现象,证明了所研究的体系中能够形成带多个单位角动量的涡旋,结果很好地解释了实验中所呈现出的令人迷惑的现象;首次研究了外加电场对快速旋转BEC的影响,发现外加电场不仅会使体系变得更加稳定,还会使涡旋格点和粒子数密度分布发生平移。我们研究了光诱导的非阿贝尔规范势在冷原子中的效应,指出振幅随时间和空间变化的激光能够直接同时诱导非阿贝尔规范矢势和标势。以快速旋转的BEC体系为例,研究了该规范势对Landau能级的性质和旋转BEC的基态相图的影响。我们研究了双原子体系中原子-分子转化的问题。研究结果表明,Feshbach共振协助的受激Raman绝热通道(STIRAP)技术能有效地将玻色-费米混合物转化为分子而单纯的Feshbach共振技术则不能。我们还用该技术研究了将处在不同自旋态上的费米混合物转化到分子的问题。通过引入相干布局数囚禁(CPT)态的保真度,我们阐明了原子-分子的转化率与体系绝热演化性质之间的联系。此外,我们研究了双势阱中不可区分的两分量BEC体系的动力学问题。我们讨论了该体系的各类不动点的存在情况及其稳定性,并从两种典型的基态出发,研究了体系的绝热演化性质,发现不同分量粒子间的相互作用会影响粒子在两个阱中的布局数,这些结果有望对实验上如何操纵BEC的粒子数分布提供参考。
与生物物质模型相关的交叉课题:我们研究了溶液环境对蛋白质折叠的影响及蛋白质集聚时类疯牛病蛋白折叠行为。我们引入溶液环境的影响来研究蛋白质结构的可设计度问题。采用了简化的HP格点模型。研究表明,当引入溶液环境的影响时,不同蛋白质序列的能隙将沿不同的方式变化,特别是,在没有溶液环境影响下具有较高能隙的序列,在引入环境影响时其能隙增加的更迅速,从而使其更稳定地处于基态。 另一方面,研究了受电场驱动二维胶体(衬底上随机分布钉杂)的动力学相,给出了相图。研究了螺旋波在极化电场下的漂移行为。数值模拟结果显示螺旋的漂移速度可以通过改变电场的极化形式来控制。当极化电场为圆偏振并且旋转方向与螺旋波方向相同时,漂移速度最大。反之,电场则将抑制漂移。基于弱形变近似的解析结果与数值结果一致。

媒体报道一:
——访国家自然科学奖二等奖获得者 长江特聘教授李有泉
走过浙大玉泉校区的邵逸夫科学馆,转一个弯就到了一座占地不大的两层小楼,小楼有些像北京的四合院,安安静静的,中间有个天井,种了些花草,这就是浙江近代物理中心。
这个小小的几乎占据了玉泉校区最高点的小楼里却是名人荟萃,教育部“长江学者”李有泉就是其中的一位。我们到的时候,被学生团团围住的李有泉从人丛中探出头来,客气地招呼着我们,原来刚刚得到国家自然科学二等奖这项崇高荣誉的李有泉昨天才从北京回来,上午给本科生上完量子力学,下午就被研究生们围住了。
强关联系统及介观体系物理方向,李有泉已经研究了多年,此次获奖的项目是“轨道简并强关联系统的SU(4)理论”,李有泉是主要完成者,这个听起来很拗口的名称着实难倒了来采访的新闻记者。谦逊的李有泉认真地解释了半天,也没能让大家听懂,他就不好意思了。其实对物理稍有关注的人都知道,对强关联电子系统的研究,多年来一直是凝聚态物理领域中富有挑战性的课题之一,李有泉他们项目组从当时与实验密切相关的理论模型入手,通过抓主要矛盾的方式简化次要因素,用非微扰方法和对称性分析方法加上必要的数值分析,深入研究了有轨道简并的系统。从而解决了用微扰方法和传统凝聚态物理方法很难处理的问题。这个创造性的理论发表在国际著名学术刊物上后,倍受业界人士关注。李有泉提出了轨道自由度有助于实现共振共价键自旋液体,指出它可以LiNiO2材料中得以实现。这个SU(4)对称性理论的发现不仅推进了国际上该领域的理论研究进程,而且对从事物理实验研究的学者有较大的启发。
从事纯理论研究的学者与做应用研究的学者有很大的不同,近代物理中心里没有一个真正意义上的实验室,这些理论物理学家的实验室就是他们发达的大脑,在需要数学推演的时候,李有泉还需要一支笔,几张纸,有时也会用计算机做些计算。谈到这个项目的创意,李有泉说,那是97年底,在美国访问时与合作者一起从不同角度的许多讨论和不断地深入研究后获得第一步重要突破的。 其实好的创意的基础在于平时的学术积累,李有泉解释,每天都有一些模型、一些图像、一些思路储存在大脑里,经过不断的数学推算、模型修正和图像完善,持之以恒,有时候就会产生“顿悟”获得飞跃性进展 。另外,与世界一流学者的接触和交流对保持高水平选题很重要。
一直以为李有泉是一个海归学者,一问才知道他还是个老浙大。1991年来到浙江近代物理中心做博士后,然后留校当老师,至今已有12年,当问到这里的工作条件时,他感叹到,浙江近代物理中心在十年前还是国内少有的硬件条件比较好的理论物理研究单位,十年来聚集了不少物理人才,为我国物理学科的发展作了很多贡献,现在中科院、清华大学、南京大学等科研院所与高校对物理研究越来越重视,硬件条件已大大超过了物理中心,言谈间流露出李有泉对近代物理中心的发展的殷切期望。 在国外做访问学者的时候,李有泉可以把几个月的时间“奢侈”地放在一个问题上,现在却有许多“重要”的事要分心,培养梯队、聘请外国专家等等,特别是很多表格之类在国外由教授的秘书可以作的事。这次采访中笔者就眼见李有泉为了为我们寻找并复印一页材料,化了十分钟时间。虽然工作状态上不去,但是这样的环境并没有难住李有泉,他已经在着手进一步的研究——强关联系统及介观体系物理研究。
除了带研究生与博士生,李有泉一周还有4节本科生的课程——《量子力学》,这是一门物理学科经典的课程之一,他坦言去上课的目的之一是想吸引更多的拔尖学生来研究物理。
离开时,我们看到李有泉办公室的小黑板上放着一盒水彩笔,原来这是李有泉他们每周六研究生例会时要用的,以前是写在黑板上,一擦就没了,后来他在国外作学术交流时学了一个好办法,每次讨论都拿大纸,用水彩笔画,写完一张就能留下来。而一个个新的理论创意就在这一张张的讨论纸的背后诞生了。

媒体报道二:
——访国家自然科学奖二等奖获得者李有泉教授
“轨道简并强关联系统的SU(4)理论”。国家科学技术奖励大会召开的当天,记者从科技部网站公布的国家自然科学奖二等奖的目录中,看到推荐单位一栏写着“浙江省”的这一获奖项目时,实在无法从这几个由汉字和英文字母组成的项目名称中看懂其研究内容。
3月3日下午,怀着好奇的心理,记者叩开位于浙江大学玉泉校区一隅的一个僻静小院——浙江近代物理中心,走近项目的主要完成者、教育部长江特聘教授李有泉。
“年轻”是李有泉留给记者的第一印象,这位国家级大奖的获得者还没吹过40岁的生日蜡烛。
李有泉的实验室和普通的办公室没有两样,只有办公桌上堆放的一叠写着各种公式、符号的草稿纸告诉人们这儿的主人从事着科学研究。“我们搞理论物理研究的,都有各种图像、模型储存在大脑里,我们思考的过程就像在做实验,当然也离不开在纸上进行数学推演,有时也会借助电脑做些计算。”在采访过程中,除了我们交谈的声音外,小院里几乎听不到其他的声音,这是个很适合思考的场所。
十几天、几十天只思考一个问题,对普通人来说几乎难以想象。李有泉说他在国外做访问学者时,经常几个月脑子里只有一个问题。他说这话时的神情告诉我,沉浸于这种思考对他来说是一种极大的享受。李有泉说,商人办公司赚钱是乐趣,对科学研究者来说科学发现才是乐趣。当然长时间考虑不出一个问题,也是常有的事,因此,做理论研究一定要耐得住寂寞,经过不断的数学推算、模型修正和图像完善,持之以恒,有时就会产生“顿悟”获得飞跃性进展。
在兰州大学从本科读到博士毕业,1991年,李有泉来到浙江大学做博士后,之后就留在浙江大学从事理论物理研究,当初的研究方向是量子场论与数学物理,1995年开始专注于凝聚态物理的研究,这是探索电子集体行为性质的非常专业的一项理论研究。虽然李有泉介绍起他获奖项目的研究内容时,记者不能理解这一理论,但从国家科学技术奖励大会颁发的项目介绍和记者检索到的各种资料的字里行间,还是掂出了这一成果在科学上的分量。据介绍,李有泉等人完成的这一研究成果发表在国际著名学术刊物上后,备受业界人士关注,称他们不仅推进了国际上该领域的理论研究进程,而且对从事物理实验研究的学者有较大的启发。
虽然已经是博导、知名教授,李有泉坚持每周给本科生上课,就在接受采访之前,他刚给一群大三学生上了《量子力学》专业课。“我给本科生上课主要是为了激发学生对理论物理研究的兴趣,能吸引一些基础好的学生到我们这里来。”就如他去年11月在浙江大学物理节上开讲座的名称“冷原子使物理热”,他做这一切就是希望能有更多的年轻人能走进浙江近代物理中心,加入到思考的队伍。让李有泉高兴的是,这几年报考物理研究生的学生多起来了。
