Adaptive sampling by information maximization
Christian K. Machens
The investigation of input-output systems often requires a sophisticated choice of test inputs to make best use of limited experimental time. Here we present an iterative algorithm…
Killing spinor equations in dimension 7 and geometry of integrable G_2-manifolds
Thomas Friedrich, Stefan Ivanov
We compute the scalar curvature of 7-dimensional -manifolds admitting a connection with totally skew-symmetric torsion. We prove the formula for the general solution of the…
The Area Law in Matrix Models for Large N QCD Strings
K. N. Anagnostopoulos, W. Bietenholz, J. Nishimura
We study the question whether matrix models obtained in the zero volume limit of 4d Yang-Mills theories can describe large N QCD strings. The matrix model we use is a variant of th…
A Note on Nonperturbative Instability in String Theory
Oleg Andreev
We investigate the possibility that stringy nonperturbative instabilities are described by worldsheet methods. We focus on the case of open bosonic string theory, where the D-insta…
Massive Dualities in Six Dimensions
K. Behrndt, E. Bergshoeff, D. Roest +1
We study compactifications of string theory and M-theory to six dimensions with background fluxes. The nonzero fluxes lead to additional mass parameters. We derive the S- and T-dua…
Intersecting Brane Worlds on Tori and Orbifolds
Ralph Blumenhagen, Boris Kors, Dieter Lust +1
We review the construction and phenomenology of intersecting brane worlds. The breaking of chiral and supersymmetry together with a reduction of gauge symmetry by introducing D-bra…
The thermal conductivity reduction in HgTe/CdTe superlattices
W. E. Bies, H. Ehrenreich, E. Runge
The techniques used previously to calculate the three-fold thermal conductivity reduction due to phonon dispersion in GaAs/AlAs superlattices (SLs) are applied to HgTe/CdTe SLs. Th…
Minimum-error discrimination between subsets of linearly dependent quantum states
Ulrike Herzog, Janos A. Bergou
A measurement strategy is developed for a new kind of hypothesis testing. It assigns, with minimum probability of error, the state of a quantum system to one or the other of two co…
Vacua of N=2 gauged supergravity derived from non-homogeneous quaternionic spaces
Klaus Behrndt, Gianguido Dall'Agata
We discuss a class of 4-dimensional non-homogeneous quaternionic spaces, which become the two known homogeneous spaces (EAdS_4$ and SU(2,1)/U(2)) in certain limits. These moduli sp…
Excited nucleon spectrum using a non-perturbatively improved clover fermion action
LHPC Collaboration, D. G. Richards, QCDSF Collaboration +8
We discuss the extraction of negative-parity baryon masses from lattice QCD calculations. The mass of the lowest-lying negative-parity state is computed in quenched l…
Nonequilibrium coupled Brownian phase oscillators
M. Kostur, J. Luczka, L. Schimansky-Geier
A model of globally coupled phase oscillators under equilibrium (driven by Gaussian white noise) and nonequilibrium (driven by symmetric dichotomic fluctuations) is studied. For th…
Binding Energy of Charged Excitons in ZnSe-based Quantum Wells
G. V. Astakhov, D. R. Yakovlev, V. P. Kochereshko +9
Excitons and charged excitons (trions) are investigated in ZnSe-based quantum well structures with (Zn,Be,Mg)Se and (Zn,Mg)(S,Se) barriers by means of magneto-optical spectroscopy.…
Properties of the renormalized quark mass in the Schrodinger functional with a non-vanishing background field
Stefan Kurth
We compute the current quark mass in the Schrodinger functional with a non-vanishing background field at one loop order of perturbation theory. The results are used to obtain the c…
Superconformal Field Theories for Compact Manifolds with Spin(7) Holonomy
Ralph Blumenhagen, Volker Braun
We present a construction of superconformal field theories for manifolds with Spin(7) holonomy. Geometrically these models correspond to the realization of Spin(7) manifolds as ant…
On the dynamics of color magnetic monopoles in full QCD
V. Bornyakov, H. Ichie, S. Kitahara +8
We present first results on the dynamics of monopoles in full QCD with N_f=2 flavors of dynamical quarks. Among the quantities being studied are the monopole density and the monopo…
Performance studies of the two-step multiboson algorithm in compact lattice QED
I. L. Bogolubsky, V. K. Mitrjushkin, I. Montvay +2
The performance of the two-step multiboson (TSMB) algorithm is investigated in comparison with the hybrid Monte Carlo (HMC) method for compact lattice QED with standard Wilson ferm…
Fast evaluation and locality of overlap fermions
W. Bietenholz, I. Hip, K. Schilling
In order to construct improved overlap fermions, we start from a short ranged approximate Ginsparg-Wilson fermion and insert it into the overlap formula. We show that its polynomia…
Systematic X-ray absorption study of hole doping in BSCCO - phases
R. Mueller, M. Schneider, R. Mitdank +6
X-ray absorption spectroscopy (XAS) on the O 1s threshold was applied to Bi-based, single crystalline high temperature superconductors (HTc's), whose hole densities in the CuO2 pla…
The SPIN Dirac operator on high tensor powers of a line bundle
Xiaonan Ma, George Marinescu
We study the asymptotic of the spectrum of the \spin Dirac operator on high tensor powers of a line bundle. As application, we get a simple proof of the main result of Guillemin-Ur…
A Remark On Field Theories On The Non-Commutative Torus
Robert C. Helling
We investigate field theories on the non-commutative torus upon varying theta, the parameter of non-commutativity. We argue that one should think of Morita equivalence as a symmetr…

L3 Collaboration
The process e+e- -> W+ W- gamma is studied using the data collected by the L3 detector at LEP. New results, corresponding to an integrated luminosity of 427.4 pb-1 at centre-of-mas…
Interlayer Exchange Coupling in M/N/M Multilayer
S. Mathi Jaya, M. C. Valsakumar, W. Nolting
The interlayer exchange coupling (IEC) of two local moment ferromagnetic layers separated by a non-magnetic spacer layer (M/N/M multilayer) is studied using the modified RKKY metho…
