TL;DR: The relation between symmetry breaking in non-commutative cut-off field theories and transitions to inhomogeneous phases in condensed matter is discussed in this article, where the authors consider the relation between short and long distance particle interactions which is responsible for the non-uniform background and the roton spectrum.

TL;DR: In this paper, the structural and optical properties of erbium doped yttrium silicates and oxides were investigated and the advantages of using bismuth as Er co-dopant, as a strategy to improve optical efficiency at 1540nm, wavelength of interest for telecommunications.

TL;DR: An analytical law is derived connecting the standard deviation of flows and their mean values and it is proved that the results are robust under different assumptions regarding network topology, routing strategy and packets injection distributions.
Abstract: Communication networks are nowadays crucial in our lives and the study of the traffic features yields important advantages. In both network and traffic design, the understanding of the relationship between the traffic on a node and its fluctuations plays a key role. In this paper, we investigate the relationship between the mean traffic flow experienced by a node and its standard deviation via numerical simulations and real data analysis. In particular, we show the great influence that the degree heterogeneity of real communication systems has on the patterns of flow fluctuations observed across complex communication networks. To this end, we derive an analytical law connecting the standard deviation of flows and their mean values, we prove it via extensive numerical simulations and by means of a realistic internet traffic simulator software: NS-3. We also show that our results are robust under different assumptions regarding network topology, routing strategy and packets injection distributions.

TL;DR: In this article, the effect of uniaxial strain on the transmission and the conductivity across a strain-induced barrier in graphene is studied. But unlike the previous work, which considers sharp barriers, this paper considers a more realistic, smooth barrier, characterized by a nonuniform, continuous strain profile.
Abstract: We study the effect of uniaxial strain on the transmission and the conductivity across a strain-induced barrier in graphene. At variance with conventional studies, which consider sharp barriers, we consider a more realistic, smooth barrier, characterized by a nonuniform, continuous strain profile. Our results are instrumental towards a better understanding of the transport properties in corrugated graphene.

TL;DR: In this article, the generalization of the Gross-Neveu model for noncommutative 3+1 space-time has been analyzed and the chiral symmetry breaking occurs for an inhomogeneous background as in the LOFF phase in condensed matter.
Abstract: The generalization of the Gross-Neveu model for noncommutative 3+1 space-time has been analyzed. We find indications that the chiral symmetry breaking occurs for an inhomogeneous background as in the LOFF phase in condensed matter.
