It is shown that the heart of the method consists in suitably describing, in a"non-classical"manner, photons steps starting from fixed light sources or from boundaries separating regions of the medium with different optical properties.
To give a better intuition of the importance of these particular photon steplengths, it is also shown numerically that the described approach is essential to preserve the invariance property for light propagation in anomalous media.
We study the confinement/deconfinement transition in the d0-brane matrixmodel (often called the bfss matrix model) and its one-parameter deformation(the bmn matrix model) numerically by lattice monte carlo simulations.
Our results confirm general expectations from the dual string/m-theory picture for strong coupling.
We study real tensor eigenvalue/vector distributions for real symmetric order-three random tensors with the gaussian distribution as the simplest case.
We first rewrite this problem as the computation of a partition function of a four-fermi theory, and find that it seems difficult to compute it exactly, and we apply an approximation using a self-consistency equation for two-point functions and obtain an analytic expression.
The origin of negative weighted events in the s-mc@nlo method is reviewed and mechanisms to reduce the negative weight fraction in simulations with the sherpa event generator are presented, with a focus on v+jets and tt+jets simulations.
