Structure and energetics of mixed 4 He - 3 He drops
نویسندگان
چکیده
Using a finite-range density functional, we have investigated the energetics and structural features of mixed helium clusters. The possibility of doping the cluster with a molecule of sulfur hexafluoride is also considered. It is seen that the repulsion introduced by the impurity strongly modifies the properties of the smallest drops. Although only a qualitative comparison is possible, the gross features displayed by our calculations are in agreement with recent experimental findings. @S0163-1829~97!02438-7#

Quantized vortices in mixed 3He-4He drops.
Using density functional theory, we investigate the structure of mixed (3)He(N3)-(4)He(N4) droplets with an embedded impurity (Xe atom or HCN molecule) which pins a quantized vortex line. We find that the dopant+vortex+(4)He(N4) complex, which in a previous work [F. Dalfovo et al., Phys. Rev. Lett. 85, 1028 (2000)] was found to be energetically stable below a critical size N(cr), is robust agai...

High Energy Density Materials (HEDMs) are a new generation of high-energetic materials with high-performance and safety and consist of several different types with different properties. One category of this kind of HEDMs explosives are high energy metal organic frameworks (HE-MOFs) that have more appropriate performance and safety compared to conventional explosives (HEMs) and even other HEDMs....

dilated fundus examination findings were normal. Blood studies were negative for antinuclear antibodies and rheumatoid factors and showed a normal complete blood count and negative angiotensin-converting enzyme levels. We diagnosed bilateral atypical Cogan syndrome in the patient. The bilateral iritis resolved with cycloplegics and topical steroid drops. The patient has been referred for a coch...
متن کاملShell structure in mixed 3 He - 4 He droplets
Due to the immiscibility of He into He at very low temperatures, mixed helium droplets consist of a core of He atoms coated by a He layer whose thickness depends on the number of atoms of each isotope. When these numbers are such that the centrifugal kinetic energy of the He atoms is small and can be considered as a perturbation to the mean-field energy, a novel shell structure arises, with mag...
متن کاملSemiotics of Power and Knowledge in Nasir Khusrow's Travelogue
Nasir Khosrow embarks upon a seven year journey in order to come to terms with his spiritual crisis. The quest was the inevitable outcome of the tensions and conflicts between Nasir and the institutionalized forms of power and knowledge. The tensions lead to the formation of a series of binary oppositions—verbal and nonverbal—within the text of his travelogue. The researchers have analyzed the ...
