The Role of Grain Boundaries in Determining the Transport Properties in Magnetite

David C. Mertens, W. Montfrooij, R. J. McQueeney +2

We present magnetoresistance and Hall-effect measurements on single crystal magnetite Fe3O4 close to the Verwey transition Tv = 123.8 K. We show that the formation of grain boundar…

Comment on "A Tale of Two Theories: Quantum Griffiths Effects in Metallic Systems" by A. H. Castro-Neto and B. A. Jones

A. J. Millis, D. K. Morr, J. Schmalian

In a recent paper Castro-Neto and Jones argue that because the observability of quantum Griffiths-McCoy effects in metals is controlled by non-universal quantities, the quantum Gri…

Impact of the inherent periodic structure on the effective medium description of left-handed and related meta-materials

Th. Koschny, P. Markos, E. N. Economou +3

We study the frequency dependence of the effective electromagnetic parameters of left-handed and related meta-materials of the split ring resonator and wire type. We show that the…

Structure of Si(114) determined by global optimization methods

F. C. Chuang, C. V. Ciobanu, C. Predescu +2

In this article we report the results of global structural optimization of the Si(114) surface, which is a stable high-index orientation of silicon. We use two independent procedur…

Superconductivity in MgB_2 doped with Ti and C

R. H. T. Wilke, S. L. Bud'ko, P. C. Canfield +6

Measurements of the superconducting upper critical field, H_{c2}, and critical current density, J_c, have been carried out for MgB_2 doped with Ti and/or C in order to explore the…

Analytic solution of the microcausality problem in Discretized Light Cone Quantization

Lubomir Martinovic, Marshall Luban

It is shown that that violation of causality in two-dimensional light-front field theories quantized in a finite ``volume'' with periodic or antiperiodic boundary conditions is…
