Low-Energy Electronic Structure of the High-Tc Cuprates La2-xSrxCuO4 Studied by Angle-resolved Photoemission Spectroscopy
T. Yoshida, X. J. Zhou, D. H. Lu +8
We have performed a systematic angle-resolved photoemission spectroscopy (ARPES) study of the high-Tc cuprates La2-xSrxCuO4, ranging from the underdoped insulator to the supercondu…
Magnetoelastic Effects and Magnetic Phase Diagram of Multiferroic
C. R. dela Cruz, B. Lorenz, Y. Y. Sun +3
The magnetoelastic coupling in multiferroic is investigated by magnetostriction measurements along the three crystallographic orientations. Strong lattice anomalies as…
Low energy excitations in graphite: The role of dimensionality and lattice defects
S. Y. Zhou, G. -H. Gweon, A. Lanzara
In this paper, we present a high resolution angle resolved photoemission spectroscopy (ARPES) study of the electronic properties of graphite. We found that the nature of the low en…
Photoemission study of (VM)O (M=Cr, Ti)
S. -K. Mo, H. -D. Kim, J. D. Denlinger +8
We present high-resolution bulk-sensitive photoemission spectra of (VM)O (M=Cr, Ti). The measurements were made for the paramagnetic metal (PM), paramagnetic in…
First direct observation of Dirac fermions in graphite
S. Y. Zhou, G. -H. Gweon, J. Graf +7
Originating from relativistic quantum field theory, Dirac fermions have been recently applied to study various peculiar phenomena in condensed matter physics, including the novel q…
Spin Liquid States on the Triangular and Kagome Lattices: A Projective Symmetry Group Analysis of Schwinger Boson States
Fa Wang, Ashvin Vishwanath
A symmetry based analysis (Projective Symmetry Group) is used to study spin liquid phases on the triangular and Kagomé lattices in the Schwinger boson framework. A maximum of eight…
