Quantum vacuum interaction between two sine-Gordon kinks
M. Bordag, J. M. Munoz-Castaneda
We calculate the quantum vacuum interaction energy between two kinks of the sine-Gordon equation. Using the --formula, the problem is reduced to the known formulas for quantu…
Interlacing inequalities for eigenvalues of discrete Laplace operators
Danijela Horak, Jürgen Jost
The term interlacing refers to systematic inequalities between the sequences of eigenvalues of two operators defined on objects related by a specific oper- ation. In particular, kn…
Nucleon sigma terms for 2+1 quark flavours
R. Horsley, Y. Nakamura, H. Perlt +7
QCD lattice simulations yield hadron masses as functions of the quark masses. From the gradients of the hadron masses the sigma terms can then be determined. We consider here dynam…
The Korteweg-de-Vries equation at H^{-1} regularity
Tristan Buckmaster, Herbert Koch
In this paper we will prove the existence of weak solutions to the Korteweg-de Vries initial value problem on the real line with H^{-1} initial data; moreover, we will study the pr…
Eigenmodes in the long-time behavior of a coupled spin system measured with nuclear magnetic resonance
Benno Meier, Jonas Kohlrautz, Jürgen Haase
The many body quantum dynamics of dipolar coupled nuclear spins I = 1/2 on an otherwise isolated cubic lattice are studied with nuclear magnetic resonance (NMR). By increasing the…
Signal Identification for Rare and Weak Features: Higher Criticism or False Discovery Rates?
Bernd Klaus, Korbinian Strimmer
Signal identification in large-dimensional settings is a challenging problem in biostatistics. Recently, the method of higher criticism (HC) was shown to be an effective means for…
