Defect-induced supersolidity with soft-core bosons
More than 40 years ago, Andreev, Lifshitz and Chester suggested the possible existence of a peculiar solid phase of matter, the microscopic constituents of which can flow superfluidly without resistance due to the formation of zero-point defects in the ground state of self-assembled crystals. Yet, a physical system where this mechanism is unambiguously established remains to be found, both expe...
متن کاملHamiltonian replica exchange molecular dynamics using soft-core interactions.
To overcome the problem of insufficient conformational sampling within biomolecular simulations, we have developed a novel Hamiltonian replica exchange molecular dynamics (H-REMD) scheme that uses soft-core interactions between those parts of the system that contribute most to high energy barriers. The advantage of this approach over other H-REMD schemes is the possibility to use a relatively s...

متن کاملCharacterization and crystallization of core streptavidin.
We have characterized a streptavidin product that had been reduced to a minimal size that still retained full biotin-binding activity. This core streptavidin is proteolyzed at both ends at points that correspond closely with the termini of hen egg white avidin. Core streptavidin is more soluble than is the parent molecule. We have grown three different types of crystals of core streptavidin. Th...
متن کاملA soft-core Gay-Berne model for the simulation of liquid crystals by Hamiltonian replica exchange.
The Gay-Berne (GB) potential has proved highly successful in the simulation of liquid crystal phases, although it is fairly demanding in terms of resources for simulations of large (e.g., N>10(5)) systems, as increasingly required in applications. Here, we introduce a soft-core GB model, which exhibits both liquid crystal phase behavior and rapid equilibration. We show that the Hamiltonian repl...
