Binomial edge ideals and conditional independence statements
Juergen Herzog, Takayuki Hibi, Freyja Hreinsdottir +2
We introduce binomial edge ideals attached to a simple graph and study their algebraic properties. We characterize those graphs for which the quadratic generators form a Gröbne…
Stochastic quantization and the role of time in quantum gravity
J. Ambjorn, R. Loll, W. Westra +1
We show that the noncritical string field theory developed from two-dimensional quantum gravity in the framework of causal dynamical triangulations can be viewed as arising through…
Quantum size effects in Pb layers with absorbed Kondo adatoms: Determination of the exchange coupling constant
U. Schwingenschlogl, I. A. Shelykh
We consider the magnetic interaction of manganese phtalocyanine (MnPc) absorbed on Pb layers which were grown on a Si substrate. We perform an ab-initio calculation of the density…
Rise and fall of the X-ray flash 080330: an off-axis jet?
C. Guidorzi, C. Clemens, S. Kobayashi +31
X-ray flashes (XRFs) are a class of gamma-ray bursts (GRBs) with the peak energy of the time-integrated spectrum, Ep, below 30 keV, whereas classical GRBs have Ep of a few hundreds…
Black holes in asymptotically Lifshitz spacetime
Ulf H. Danielsson, Larus Thorlacius
A model of 3+1 dimensional gravity with negative cosmological constant coupled to abelian gauge fields has been proposed as a gravity dual for Lifshitz like critical phenomena in 2…
N=2 world-sheet approach to D-branes on generalized Kaehler geometries: II. Dualities
Alexander Sevrin, Wieland Staessens, Alexander Wijns
Following the general formalism reviewed in 0810.5355 [hep-th] we present several examples of possible D3-brane configurations on four-dimensional generalized Kaehler geometries. W…
