ShareONE-DIMENSIONAL SUPERFLUIDITY IN BOSE CRYSTALS.
[In Russian. / En russe.]
Author(s) : SEVCENKO S. I.
Type of article: Article
Summary
THE POSSIBILITY OF DELOCALIZATION OF THE QUANTUM CRYSTAL PARTI CLES IN THE DISLOCATION CORE AND OF THE DELOCALIZED PARTICLE TRANSITION TO THE SUPERFLUID STATE IS PREDICTED. THE THEORY OF ONE-DIMENSIONAL SUPERFLUIDITY OF SLIGHTLY IMPERFECT BOSE GAS IS DEVELOPED. THE STUDIES OF IMPURITY EFFECT ON THE SUPERFLUID DENSITY SHOW THAT IMPURITIES DO NOT DESTROY SUPERFLUIDITY BUT MAKE AN ADDITIONAL CONTRIBUTION TO THE NORMAL COMPONENT, EVEN AT T = 0. THE SUPERFLUID FLOW THROUGH A WEAK LINK IS EXAMINED.
