Finite-Size Scaling in the Driven Lattice Gas
Sergio Caracciolo, Andrea Gambassi, Massimiliano Gubinelli +1
We present a Monte Carlo study of the high-temperature phase of the two-dimensional driven lattice gas at infinite driving field. We define a finite-volume correlation length, veri…
Coulomb Drag as a Probe of the Nature of Compressible States in a Magnetic Field
K. Muraki, J. G. S. Lok, S. Kraus +5
Magneto-drag reveals the nature of compressible states and the underlying interplay of disorder and interactions. At ν=3/2 a clear T^{4/3} dependence is observed, which signifies t…
Evidence for CuO conducting band splitting in the nodal direction of Bi-2212
A. A. Kordyuk, S. V. Borisenko, A. N. Yaresko +12
Using angle-resolved photoemission spectroscopy with ultimate momentum resolution we have explicitly resolved the bilayer splitting in the nodal direction of Bi-2212. The splitting…
Two resonant magnetic modes in an overdoped high- superconductor
S. Pailhes, Y. Sidis, P. Bourges +8
A detailed inelastic neutron scattering study of the overdoped high temperature copper oxide superconductor reveals two distinct magnetic resonan…
Electron-phonon interaction in the t-J model
O. Rösch, O. Gunnarsson
We derive a t-J model with electron-phonon coupling from the three-band model, considering modulation of both hopping and Coulomb integrals by phonons. While the modulation of the…
Excitonic and Quasiparticle Life Time Effects on Silicon Electron Energy Loss Spectrum from First Principles
B. Arnaud, S. Lebègue, M. Alouani
The quasiparticle decays due to electron-electron interaction in silicon are studied by means of first-principles all-electron GW approximation. The spectral function as well as th…
