The Purdue University’s Quantum Foundations and Quantum Photonics Laboratory (Prof. Tongcang Li’s group) has open positions for self-motivated excellent postdocs, graduate students, visiting students and visiting scholars starting from 08/2014. Tongcang Li Assistant Professor of Physics and Astronomy Assistant Professor of Electrical and Computer Engineering Purdue University Email: tcli@purdue.edu https://sites.google.com/site/litongcang/ Selected publications: 1. Peng Zhang, Tongcang Li, Jie Zhu, et al. Nature Communications, forthcoming (2014) 2. S. Kheifets, A. Simha, K. Melin, Tongcang Li, M. G. Raizen. Science, 343, 1493 (2014) 3. Tongcang Li, Z.-X. Gong, Z.-Q. Yin, et al. Phys. Rev. Lett., 109, 163001 (2012) (cover story) 4. Peng Zhang, Yi Hu, Tongcang Li, et al. Phys. Rev. Lett. 109, 193901 (2012) (cover story) 5. Tongcang Li, Simon Kheifets, Mark G. Raizen, Nature Physics, 7, 527 (2011) 6. Tongcang Li, S. Kheifets, D. Medellin, and M. G. Raizen. Science, 328, 1673 (2010) Research topics include but are not limited to: 1. Quantum spin-optomechanics of levitated nanodiamonds A levitated nanodiamond with a built-in NV center is an analog of an atom trapped in vacuum, but provides a much larger mass for studying macroscopic quantum mechanics. It eliminates the physical contact inherent to clamped cantilevers and has internal electronic states for convenient quantum control. These properties enable unprecedented force sensitivity and the creation of large spatial superposition states. These large spatial superposition states can be used to study objective collapse theories of quantum mechanics, which propose that the Schrodinger equation is only an approximate theory that breaks down when objects above a critical mass are delocalized over a critical distance. 2. Interfacing cold atoms and plasmonic nanostructures The coupling between atoms and photons is essential for many applications in quantum information science. Here we plan to couple atoms to nano-plasmonic structures. Because of their large negative electric permittivity, metallic structures can support plasmonic resonances that confine photons below diffraction limit. This strong confinement of photons can dramatically enhance the interacting between photons and atoms, reduce the size of the device, and thus increase the scalability for studying quantum optics and many-body physics. |

本科或碩士是凝聚態(tài)方向完全沒(méi)問(wèn)題。關(guān)鍵是內(nèi)心要熱愛(ài)科學(xué)研究，做事認(rèn)真負(fù)責(zé)，同時(shí)思維活躍。 我的本科就是凝聚態(tài)專業(yè)，發(fā)過(guò)幾篇自旋電子學(xué)和碳納米管的論文。博士前幾年做冷原子實(shí)驗(yàn)，后來(lái)把冷原子和凝聚態(tài)相結(jié)合，提出并開始了真空中激光束縛和冷卻微納粒子的實(shí)驗(yàn)。博士畢業(yè)后去了一個(gè)納米光學(xué)實(shí)驗(yàn)室做博士后，現(xiàn)在去普渡大學(xué)物理和天文系以及電子工程和計(jì)算機(jī)系做雙聘助理教授。 我有兩個(gè)重要工作都是凝聚態(tài)和原子、分子、光學(xué)相結(jié)合的：1. 用超精密激光光鑷測(cè)量了微粒布朗運(yùn)動(dòng)的瞬時(shí)速度，完成了這個(gè)愛(ài)因斯坦在100多年前認(rèn)為是不可能完成的任務(wù)。這個(gè)工作發(fā)表在Science雜志并被該雜志推薦為高中和大學(xué)教學(xué)內(nèi)容： Experiments Einstein Could Only Dream Of：Measurement of the Instantaneous Velocity of a Brownian Particle. http://scienceintheclassroom.org/?tid=18 2. 首次提出用超冷離子來(lái)制備“時(shí)空晶體”。這個(gè)工作發(fā)表在Phys Rev Lett 封面，被Nature等雜志廣泛報(bào)道，并被Discover旗下頻道拍攝紀(jì)錄片。Nature： Building a space-time crystal. http://www.nature.com/nature/journal/v491/n7422/full/491011c.html 美國(guó)普渡大學(xué)擁有自己的飛機(jī)場(chǎng)，培養(yǎng)了人類登月第一人阿姆斯特朗，中國(guó)原子彈之父鄧稼先（1950年博士畢業(yè)于普渡大學(xué)物理系）等人。有5名校友得過(guò)諾貝爾物理學(xué)獎(jiǎng)，它的電子工程和計(jì)算機(jī)系在美國(guó)排名前十，發(fā)明了全電子電視機(jī)，維基（wiki）等技術(shù)，是做前沿科學(xué)研究的好地方。 |
