Observation of metastable hcp solid helium
We have produced and observed metastable solid helium-4 below its melting pressure between 1.1 K and 1.4 K. This is achieved by an intense pressure wave carefully focused inside a crystal of known orientation. An accurate density map of the focal zone is provided by an optical interferometric technique. Depending on the sample, minimum density achieved at focus corresponds to pressures between ...
متن کاملProperties of Metastable Solid Helium Below the Normal Melting Pressure
In this note we report on simple estimates of the properties of metastable solid helium that is at a pressure below the normal melting pressure. We calculate the nucleation rate for formation of the liquid phase and estimate the “spinodal” pressure at which the solid becomes macroscopically unstable.
متن کاملA metastable liquid melted from a crystalline solid under decompression
A metastable liquid may exist under supercooling, sustaining the liquid below the melting point such as supercooled water and silicon. It may also exist as a transient state in solid-solid transitions, as demonstrated in recent studies of colloidal particles and glass-forming metallic systems. One important question is whether a crystalline solid may directly melt into a sustainable metastable ...
متن کاملInherent structures in the potential energy landscape of solid 4 He
We study the potential energy landscape ~many-atom potential energy as a function of atomic positions! of solid hcp He in the vicinity of the 0 K crystal structure using an accurate pair potential. At the melting point, the potential energy of the helium lattice is far above the minimum hcp interatomic potential energy. We confirm previous conclusions ~based on less accurate potentials! that al...
متن کاملDislocation Structure and Mobility in Hcp Rare-Gas Solids: Quantum versus Classical
We study the structural and mobility properties of edge dislocations in rare-gas crystals with the hexagonal close-packed (hcp) structure by using classical simulation techniques. Our results are discussed in the light of recent experimental and theoretical studies on hcp 4He, an archetypal quantum crystal. According to our simulations classical hcp rare-gas crystals present a strong tendency t...
