Laser diffraction by periodic dynamic patterns in anisotropic fluids
Th. John, U. Behn, R. Stannarius
This paper describes the application of a laser diffraction technique to the study of electroconvection in nematic liquid crystal cells. It allows a real-time quantitative access t…
Reentrant Metallic Behavior of Graphite in the Quantum Limit
Y. Kopelevich, J. H. S. Torres, R. R. da Silva +3
Magnetotransport measurements performed on several well-characterized highly oriented pyrolitic graphite and single crystalline Kish graphite samples reveal a reentrant metallic be…
Absence of Metal-Insulator-Transition and Coherent Interlayer Transport in oriented graphite in parallel magnetic fields
H. Kempa, H. C. Semmelhack, P. Esquinazi +1
Measurements of the magnetoresistivity of graphite with a high degree of control of the angle between the sample and magnetic field indicate that the metal-insulator transition (MI…
Field-induced metal-insulator Field-induced metal-insulator transition in the c-axis resistivity of graphite
H. Kempa, P. Esquinazi, Y. Kopelevich
We show that the resistivity perpendicular and parallel to the basal planes of different graphite samples show similar magnetic-field-driven metal-insulator-transitions…
Flow to strong coupling in the two-dimensional Hubbard model
C. Honerkamp, M. Salmhofer, T. M. Rice
We extend the analysis of the renormalization group flow in the two-dimensional Hubbard model close to half-filling using the recently developed temperature flow formalism. We inve…
Green's function of the half-filled Landau level Chern-Simons theory in the temporal gauge
J. Dietel
We study the Green's function of the Chern-Simons system in the temporal (Weyl) gauge. We derive the Chern-Simons path integral in the temporal gauge. In order to do this…
