Properties of one- and two-electron bubbles in superfluid 4He at 0 K were studied by density functional theory. The model allows for accurate treatment of both the electronic and liquid degrees of freedom and as such, enables accurate calculation of bubble energetics for the ground and excited...
Impurity–helium (Im–He) solids are porous materials formed inside superfluid 4He by nanoclusters of impurities injected from the gas phase. The results of studies of these materials have relevance to soft condensed matter physics, matrix isolation of free radicals and low temperature chemistry....
Within the framework of the self-consistent scheme proposed by Singwi, Tosi, Land and Sjölander (STLS) for an interacting system we study the properties of superfluid liquid 4He. By employing the Aziz potential (HFD-B) as the interaction potential between helium atoms, we have calculated the...
Fluctuation induced conductivity of Ca substitution at R sites of R1−x
: 123 superconductors with various x and R is investigated. This work is done by using the reported data of Sedky et al. (Phys. Rev. B 58(18):12495, 1998). The logarithmic plots of Δσ and reduced temperature € reveal...
For decades, the conventional view is that an s-wave BCS superfluid can not support uniform spin polarization due to a gap Δ in the quasiparticle excitation spectrum. We show that this is an artifact of the dismissal of quasiparticle interactions V
in the conventional approach at the...
