Greetings: Hai-hu WEN and Dong-lai FENG won the 2010 Achievement in Asia Award (Robert T. Poe Prize)

2010, Volume 5, Number 4

Professor Hai-hu WEN (Institute of Physics, Chinese Academy of Sciences) and Prof. Dong-lai FENG (Fudan University, China) are the co-winner of the 2010 Achievement in Asia Award (AAA) (ROBERT T. POE PRIZE) of the Overseas Chinese Physics Association (OCPA). The OCPA AAA Award is given annually to Chinese physicists working in Asia in recognition of their outstanding achievements in physics.

Professor Hai-hu WEN has been working and studying in the field of high temperature superconductivity since 1985. He received his Ph.D. degree in 1991 at Institute of Plasma Physics, CAS. Then he spent two years (1991－1993) at Free University, Amsterdam, the Netherlands, as a postdoc. From 1996－1998 he worked as an Alexander von Humboldt fellow in Ulm University, Germany. He wasgot established aspromoted to the a full professor position in 1996 atin Institute of Physics, CAS. In 1998, Hhe wongot the Outstanding Chinese Young Scholar’s award fromby NSFC in 1998. From 2000－2009 he served as the director of the National Lab for Superconductivity. Now he is the director of the national 973 project for fundamental research in superconductivity in China. HIn addition, he is also serving as anthe editorial member of Physica C, Chinese Physics Letters, Science in China G, etc.

Professor Wen's area of research covers broadly in the field of superconductivity: material synthesizing, pairing mechanism and flux dynamics of unconventional superconductors. In the cuprate superconductors, he and his colleagues invented the Generalized Inversion Scheme for directly converting the intrinsic vortex pinning energy and critical current density. Meanwhile he has found the magnetic field induced crossover from 3-D to 2-D of the vortex system and the Kosterlitz－Thouless transition in the 2212 cuprate superconductors. He has also made significant contributions to the superconducting mechanism in the cuprate superconductors, for example, he found the evidence of phase separation in the overdoped cuprate superconductors, and the existence of incoherent electron pairs far above Tc (through entropy) in the underdoped cuprates. His group rises up as one of the leading ones in the research of iron pnictide superconductors. They fabricated the first hole doped superconductors in the FeAs family. They are Aamong the very earliest people who have, they grownew the single crystals of the FeAs-1111 system, and measured the first set of transport data and , found the very small anisotropy. They also discovered the new structure FeAs-32522 and the new superconductor Sr4V2O6Fe2As2, as well as the Fluorine derivative system REFeAsF (RE=rare earth elements) and found superconductivity at 57 K. His refined specific heat, point contact tunneling and transport measurements reveal the importance of multiband feature and antiferromagnetic spin fluctuations in the pairing mechanism of the iron pnictide

superconductor.

Professor Dong-lai FENG received his B. S. (1994) and M. S. (1996) degrees in physics at the University of Science and Technology of China, and his Ph.D. degree in 2001 at Stanford University in the United States with Prof. Zhi-xun SHEN. He then spent two and a half years as a postdoctoral fellow in the University of British Columbia, Canada with Prof. George A. Sawatzky. He started to work at Fudan University since 2002, and now is the Hao－-Qin Chair professor in the Department of Physics at Fudan University.

Professor Feng's research area is of research is experimental condensed matter physics. His work on high temperature superconductivity and ordering phenomena in solids, and his achievement in high-resolution angle resolved photoemission spectroscopy are particularly notable. His group at Fudan has made a few important discoveries, such as the large scale dispersion and coherence peak in single layer copper-oxide superconductors, the large scale band reconstruction associated with the unconventional spin density wave in iron-based superconductors, and a novel strong-coupling mechanism for the long standing mystery of charge density waves in transition metal dichalcogenides. His other contributions include extending the inelastic X-ray scattering technique to study the exitons in organic molecular crystals and small molecules, developing the resonant soft x-ray scattering technique to study ordering in complex materials, and revealing the electronic structure at strained oxide interfaces, which is crucial for the future application of oxide electronics. He has been awarded the "Javed Hussain Prize for young scientist" by the UNESCO in 2005.
