Ru, N., Borzi, R. A., Rost, A., Mackenzie, A. P., Laverock, J., Dugdale, S. B., ...
De Haas-van Alphen oscillations were measured in lanthanum tritelluride (LaTe_3) to probe the partially gapped Fermi surface resulting from charge density wave (CDW) formation. Three distinct...
Ru, N., Chu, J. -H., Fisher, I. R.
The antiferromagnetic transition is investigated in the rare-earth (R) tritelluride RTe3 family of charge density wave (CDW) compounds via specific heat, magnetization and resistivity measurements....
Brouet, V., Yang, W. L., Zhou, X. J., Hussain, Z., Moore, R. G., He, R., ...
We present a detailed ARPES investigation of the RTe3 family, which sets this system as an ideal "textbook" example for the formation of a nesting driven Charge Density Wave (CDW). This family indeed...
STM Studies of TbTe3: Evidence for a fully Incommensurate Charge Density Wave (2007)
Fang, A., Ru, N., Fisher, I. R., Kapitulnik, A.
We observe unidirectional charge density wave ordering on the cleaved surface of TbTe3 with a Scanning Tunneling Microscope at ~6 K. The modulation wave-vector q_{CDW} as determined by Fourier...
Ru, N., Condron, C. L., Margulis, G. Y., Shin, K. Y., Laverock, J., Dugdale, S. B., ...
The charge density wave transition is investigated in the bi-layer family of rare earth tritelluride RTe_3 compounds (R = Sm, Gd, Tb, Dy, Ho, Er, Tm) via high resolution x-ray diffraction and...
Pressure dependence of the charge-density-wave gap in rare-earth tri-tellurides (2006)
Sacchetti, A., Arcangeletti, E., Perucchi, A., Baldassarre, L., Postorino, P., Lupi, S., ...
We investigate the pressure dependence of the optical properties of CeTe$_3$, which exhibits an incommensurate charge-density-wave (CDW) state already at 300 K. Our data are collected in the...
Sacchetti, A., Degiorgi, L., Giamarchi, T., Ru, N., Fisher, I. R.
We report on the first optical measurements of the rare-earth tri-telluride charge-density-wave systems. Our data, collected over an extremely broad spectral range, allow us to observe both the Drude...
Fermi surface nesting and charge-density wave formation in rare-earth tritellurides (2005)
Laverock, J., Dugdale, S. B., Major, Zs., Alam, M. A., Ru, N., Fisher, I. R., ...
The Fermi surface of rare-earth tri-tellurides ({\it R}Te$_{3}$) is investigated in terms of the nesting driven charge-density wave formation using positron annihilation and first-principles LMTO...
Fermi Surface reconstruction in the CDW state of CeTe3 observed by photoemission (2004)
Brouet, V., Yang, W. L., Zhou, X. J., Hussain, Z., Ru, N., Shin, K. Y., ...
CeTe3 is a layered compound where an incommensurate Charge Density Wave (CDW) opens a large gap (400 meV) in optimally nested regions of the Fermi Surface (FS), whereas other sections with poorer...
Automatic Completely-Simple Semigroups (2000)
N. Ru, Skuc (st Andrews, R. M. Thomas (leicester
The notion of automaticity has been widely studied in groups and some progress has been made in understanding the notion in the wider context of semigroups. The purpose of this paper is to study...
