Towards a Comprehensive Theory for He II: II. A Temperature-Dependent Field-Theoretic Approach

摘要

New experimental aspects of He II are used as a guide towards a comprehensive theory in which non-zero temperature U(1) and SU(2) gauge fields are incorporated into a gauge hierarchy of effective Lagrangians. We conjecture that an SU(n) gauge-theoretic description of the superfluidity of exp 4 He may be obtained in the limit n implies infinity. We indicate, however, how experiments may be understood in the zeroth, first and second order of the hierarchy. (Atomindex citation 14:753065)
