Analytic Model for the Energy Spectrum of a Graphene Quantum Dot in a Perpendicular Magnetic Field
S. Schnez, K. Ensslin, M. Sigrist +1
We analytically calculate the energy spectrum of a circular graphene quantum dot with radius R subjected to a perpendicular magnetic field B by applying the infinite-mass boundary…
Vortex avalanches in the non-centrosymmetric superconductor Li2Pt3B
C. F. Miclea, A. C. Mota, M. Sigrist +5
We investigated the vortex dynamics in the non-centrosymmetric superconductor Li_2Pt_3B in the temperature range 0.1 K - 2.8 K. Two different logarithmic creep regimes in the decay…
Nature of Stripes in the Generalized t-J Model Applied to The Cuprate Superconductors
Kai-Yu Yang, Wei-Qiang Chen, T. M. Rice +2
Recent transport properties on the stripe phase in LaBaCuO by Li \textit{et al.} found 2-dimensional superconductivity over a wide te…
Breakdown of Landau Theory in Overdoped Cuprates near the Onset of Superconductivity
M. Ossadnik, C. Honerkamp, T. M. Rice +1
We use the functional renormalization group to analyze the temperature dependence of the quasi-particle scattering rates in the two-dimensional Hubbard model below half-filling. Us…
First-order transition between a small-gap semiconductor and a ferromagnetic metal in the isoelectronic alloys FeSiGe
V. I. Anisimov, R. Hlubina, M. A. Korotin +4
The contrasting groundstates of isoelectronic and isostructural FeSi and FeGe can be explained within an extended local density approximation scheme (LDA+U) by an appropriate choic…
Magnetic imaging of the paramagnetic Meissner effect in the granular high-Tc superconductor Bi2Sr2CaCu2Ox
J. R. Kirtley, A. C. Mota, M. Sigrist +1
We have imaged the spatial distribution of magnetic flux on a granular sample of the high-temperature superconductor Bi2Sr2CaCu2Ox using a scanning SQUID microscope. Our results es…
