We propose a protocol for the scalable quantum simulation of SU($N$)$ imes$U(1) lattice gauge theories with alkaline-earth like atoms in optical lattices in both one- and two-dimensional systems.The protocol exploits the combination of naturally occurring SU($N$) pseudo-spin symmetry and strong inter-orbital interactions that is unique to such atom

In order to predict the immunity of a generic missile (GENEC), not only the electronic system click here but also the enclosure has to be taken into consideration.While a completely closed metallic missile enclosure shows a high electric shielding effectiveness, it is decreased substantially by apertures which could not be avoided by read more diff

Abstract Background Karst areas in southwestern China exhibit ecological degradation in the form of rocky desertification.Local governments launched large-scale afforestation and other ecological restoration programs to curb this trend.Soil thickness is a key limiting factor for vegetation restoration in Karst areas, but the relationship between ec

The contrast in bed roughness versus apron roughness has, until recently, received insufficient attention, despite its significant role in causing downstream scouring.In this study, a validated numerical model has employed to investigate the impact of apron geometry, including its roughness and length, on downstream scouring.In present model, at fi
