Static and Dynamic Critical Phenomena near the Superfluid Transition in 4He

摘要: It is widely appreciated that the superfluid transition in liquid 4He an exceptionally suitable system for detailed experimental investigations of continuous phase transitions. Its merits and limitations have been discussed detail elsewhere, 1,2 results on static properties reviewed detail.2 In present lectures, I would like to provide a summary some recent developments our understanding then discuss behavior singularities transport properties. Before proceeding this, however, it useful review more general not limited which pertain nature confluent singularities. These strong bearing interpretation near
