Technical Research Interest:

Jiang's group is actively working on the solid-state implementations of quantum information processing using electron spins in semiconductor nanostructures. The group is currently developing a fundamental building block for quantum computation and quantum communications with advanced semiconductor nanostructures, called spin-resonance-transistors. The ongoing effort includes the electrically controlled manipulation of electron and nuclear spins, detection of the quantum states of a single electron spin, nanofabrication of solid state traps (i.e., quantum bits) and read-out channels. The group has recently made the first measurement of the magnetic spin resonance of a single electron. Another area of research of the group is in experimental condensed matter physics: quantum phase transition and localization phenomena in highly correlated lowdimensional electronic systems. The group's recent focus is on high-sensitivity thermodynamic measurements of interacting disordered semiconductor heterostructures. The thermodynamic measurements provide means to probe the many-body ground state properties of the interacting charge carriers. Jiang's group has made several path-breaking discoveries on the studies of quantum Hall systems over the years.

Additional Information:

Hong-Wen Jiang received a Ph.D. degree in physics from Case Western Reserve University in 1989, where he studied under the direction of Prof. Arnold Dahm. Jiang was a Postdoctoral Fellow at Princeton University from 1989-91, where he worked with Prof. Dan Tsui and Dr. Horst Stormer. He joined the Department of Physics at UCLA as an Assistant Professor in 1991. He was promoted to tenure in 1994, and to Full Professor in 1998. Jiang was an Alfred P. Sloan Fellow (1992-94) and he was the recipient of the 1993 William L. McMillan Award for outstanding contributions in condensed matter physics "for his ground-breaking experiments on the interactions between electrons and magnetic fields in various quantum Hall systems and electron localization phenomena". He also received the 1996 Overseas Chinese Physics Association Outstanding Young Researcher Award "for the study of the quantum Hall effect and the discovery of the magnetic-field-induced delocalization transition". At UCLA, he has been given the Outstanding Teaching Award by the physics department 9 times in the last 11 years.
