The zero temperature properties of interacting 2 dimensional lattice bosons are investigated. We present Monte Carlo data for soft-core bosons that demonstrate the existence of a phase in which crystalline long-range order and off-diagonal long-range order (superfluidity) coexist. We comment on the difference between hard and soft-core bosons and compare our data to mean-field results that pred...

This letter presents the design, development, and experimental assessment of a soft fluidic actuator that can enable locomotion in variety aquatic terrestrial environments. Most actuation strategies for amphibious rely on rigid, fast moving components to generate thrust tractive forces. Our prototype, comprising materials, relying simple motion planning control strategies, demonstrates two gait...
