Resonant raman scattering of the smallest single-walled carbon nanotubes (2008)
Tang, Zi-Kang, Zhai, J. P., Tong, Y. Y., Hu, Xijun, Saito, R., Feng, Y. J., ...
We report optical properties of the smallest single-walled carbon nanotubes (SWNTs) with a diameter of only 3Å . These ultrasmall SWNTs are fabricated in the elliptical nanochannels of an AlPO-11...

Evaluation of Multiloop Diagrams via Lightcone Integration (1997)
We present a systematic method to determine the dominant regions of internal momenta contributing to any two-body high-energy near-forward scattering diagram. Such a knowledge is used to evaluate...
Generalized Background-Field Method (1997)
The graphical method discussed previously can be used to create new gauges not reachable by the path-integral formalism. By this means a new gauge is designed for more efficient two-loop QCD...
Gauge Cancellation for Electroweak Processes and the Gervais-Neveu Gauge (1996)
A graphical method is developed to study the total or partial cancellation of gauge-dependent (divergence) terms in electroweak theory. The method is used to work out rules in the Gervais-Neveu...
Multiple Reggeon Exchange from Summing QCD Feynman Diagrams (1996)
Multiple reggeon exchange supplies subleading logs that may be used to restore unitarity to the Low-Nussinov Pomeron, provided it can be proven that the sum of Feynman diagrams to all orders gives...
Cut Diagrams for High Energy Scatterings (1996)
Feng, Y. J., Hamidi-Ravari, O., Lam, C. S.
A new approach is introduced to study QCD amplitudes at high energy and comparatively small momentum transfer. Novel cut diagrams, representing resummation of Feynman diagrams, are used to simplify...
DIAGRAMMATIC ANALYSIS OF QCD GAUGE TRANSFORMATIONS AND GAUGE CANCELLATIONS (1995)
Diagrammatic techniques are invented to implement QCD gauge transformations. These techniques can be used to discover how gauge-dependent terms are cancelled among diagrams to yield gauge-invariant...
String Organization of Field Theories: Duality and Gauge Invariance (1994)
String theories should reduce to ordinary four-dimensional field theories at low energies. Yet the formulation of the two are so different that such a connection, if it exists, is not immediately...
