About

 

Yupeng Wang was born in 1965. He graduated from the Department of Optics of Shandong University in 1984 and obtained his PhD from Institute of Physics (IOP), Chinese Academy of Sciences (CAS) in 1994. He was a visiting scholar at the physics departments of University of Augsburg (Humboldt Research Fellowship), University of Bayreuth and Florida State University. In 1996, he became Professor of the Cryogenic Laboratory, CAS and became the group leader of Condensed Matter Physics Research Centre of IOP, CAS in 1999. He was promoted to Assistant Director of IOP, CAS and Chairman of Condensed Matter and Material Computation Laboratory in 2001, and became Vice Director of IOP, CAS in 2003. He has now been the director of IOP, CAS since 2007.
He won the "Outstanding Young Scholar Award" of Hong Kong Qiushi Foundation and the "National Outstanding Youth Science Foundation" in 1998. His science citation index of single paper was ranked the seventh in China in 1999. He received the "Young Scientists Award of Chinese Academy" of Science in 2001, "National Outstanding Scientific Workers" in 2004, "Beijing Mao Yi-Sheng Science and Technology Awards" and "Ye Qi-Sung Award of Chinese Physics Society" in 2005. He is in charge of more than ten different major national research foundations, such as key projects National Natural Science Foundation of China (NSFC), major projects of CAS, National Basic Research Program of China (973 Program), etc.

 

Research interests

 

Low-dimensional strongly correlated electron systems are the research focus of Key Laboratory of Condensed Matter Theory and Computation, Chinese Academy of Sciences. It includes quantum Hall effect, giant magnetoresistance, organic-conductors, nanosystems, two-dimensional electron gas, carbon nanotubes, etc.
Prof. Wang’s research interest includes fermionic high-spin system in condensed matter,, metal-insulator transition in the low-dimension conductor, elementary topological excitations, mechanisms of unconventional superconductivity, spintronics and spin current mechanisms of quantum dots, theoretical issues related to quantum computation, etc. As artificial nano-periodic structure is a new state of matter and has potential applications in the electronic devices of next generation, he is also interested to study the transport properties of such system.

Achievements and publications

 

1. Studied the magnetic impurities of low-dimensional strongly correlated electron systems and proposed the “ghost spin” phenomenon, the representative paper has been cited for more than hundred times.
2. Proposed the edge critical exponents theory of Luttinger liquid, which paves the way to study the transport properties of quasi- one-dimensional conductors.
3. Proposed the light rare earth doping theory for 123 phase high Tc superconductors, and has explained and predicted many experimental phenomena.
4. Proposed the correspondence between Luttinger liquid theory and Fermi liquid theory.
5. Proposed the SU(4) spin ladder model and first observed the modulated structure caused by frustration.
6. Studied the spin-polarized transport properties of quantum dots.
7. Proposed the spin-singlet BCS state of P-wave pairing in band-degenerated superconductor systems.
8. Studied the decoherence mechanics of quantum dots.
