Observation of Enhanced Transformer Ratio in Collinear Wakefield Acceleration (2007)
Jing, C., Kanareykin, A., Power, J. G., Conde, M., Yusof, Z., Schoessow, P., ...
One approach to future high energy particle accelerators is based on the wakefield principle: a leading high-charge drive bunch is used to excite fields in an accelerating structure or plasma that in...
ARPES Study of the Metal-Insulator Transition in Bismuth Cobaltates (2006)
Yusof, Z., Wells, B. O., Valla, T., Johnson, P. D., Fedorov, A. V., Li, Q., ...
We present an angle-resolved photoemission spectroscopy (ARPES) study of a Mott-Hubbard-type bismuth cobaltate system across a metal-insulator transition. By varying the amount of Pb substitution,...
Romano, P., Ozyuzer, L., Yusof, Z., Kurter, C., Zasadzinski, J. F.
The tunneling spectra of high temperature superconductors on Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ (Bi-2212) reproducibly show a high bias structure in the form of a dip-hump at voltages higher than the...
Power, J. G., Wang, H., Conde, M. E., Gai, W., Konecny, R., Liu, W., ...
In its normal mode of operation the Argonne Wakefield Accelerator Facility uses a high charge (10-100 nC), short pulse (3-5 psec) drive bunch to excite high-gradient accelerating fields in various...
Coherence-Incoherence and Dimensional Crossover in Layered Strongly Correlated Metals (2002)
Valla, T., Johnson, P. D., Yusof, Z., Wells, B., Li, Q., Loureiro, S. M., ...
Correlations between electrons and the effective dimensionality are crucial factors that shape the properties of an interacting electron system. For example, the onsite Coulomb repulsion, U, may...
Quasiparticle Liquid in the Highly Overdoped Bi2212 (2001)

High-resolution photoemission is used to study the electronic structure of the cuprate superconductor, Bi2212, as a function of hole doping and temperature. A kink observed in the band dispersion in...
Tunneling Spectroscopy of Tl2Ba2CuO6 (1999)
Ozyuzer, L., Yusof, Z., Zasadzinski, J. F., Hinks, D. G., Gray, K. E.
New results from tunneling spectroscopies on near optimally-doped single crystals of Tl_{2}Ba_{2}CuO_{6} (Tl-2201) junctions are presented. The superconductor-insulator-normal metal (SIN) tunnel...
Comment on Recent Tunneling Measurements on Bi-2212 (1998)
The asymmetry in the conductance peaks shown in recent PCT and STM measurements may be a signature of the d-wave gap. This is based on our model for the tunneling density of states (DOS) which...
