Experiment on consumer behaviour in fashion E-commerce – experience and insights

As e-commerce continues to grow, so do the competition and expectations from consumers. To meet these challenges, e-tailers need to become more streamlined and understand the behaviour of their customers. An experiment was performed to gain knowledge about the impact of delivery and returns policies on consumer buying behaviour. Realistic and trustworthy results were generated by using a random sa

Dynamical Mean-Field Theory for Doped Antiferromagnets

We have generalized the dynamical mean-field theory to study the doping dependence of the crossover from antiferromagnetic to short-range order modeled by an incommensurate spin density wave in the Hubbard model. The local self-energy which includes spin fluctuations gives quasiparticle weights and spectral properties in good agreement with quantum Monte Carlo and exact diagonalization data in two

Transient Electromagnetic Wave Propagation in Transverse Periodic Media

In this paper, wave propagation of electromagnetic pulses in media that are periodic in one spatial direction is analyzed by a time domain technique. The special case of wave propagation in an inhomogeneous planar waveguide with perfectly conducting walls is also discussed. The wave equation is reduced to a set of one dimensional first order hyperbolic equations by an expansion in a complete set o
