Renormalization-group Theory and Universality along the Lambda Line Of
The present status of the renormalization-group (RG) predictions on the superfluid density ρ s and the specific heat C + and C − near the λ-line of 4 He is briefly reviewed. Particular attention is given to universal amplitude ratios related to these quantities. The goals of a new theory project are presented that involves higher-order calculations of the amplitude functions of ρ s , C + and C ...
متن کاملUniversality of Critical-point Exponents with Respect to Lattice Anisotropy*
The universality hypothesis [l] is designed to provide an answer to the question ‘On what features of an interaction Hamiltonian do criticalpoint exponents depend ? ‘. The validity of the universality hypotheses has been seriously questioned by recent results [2-41 that certain exponents for a special sort of two-dimensional Ising-like model varied smoothly with the magnitude of a fourspin inte...
متن کاملAdiabatic waves along interfacial layers near the critical point
Near the critical point, isothermal interfacial zones are investigated starting from a non-local density of energy. From the equations of motion of thermocapillary fluids [1], we point out a new kind of adiabatic waves propagating along the interfacial layers. The waves are associated with the second derivatives of densities and propagate with a celerity depending on the proximity of the critic...
متن کاملSolvability of an impulsive boundary value problem on the half-line via critical point theory
In this paper, an impulsive boundary value problem on the half-line is considered and existence of solutions is proved using Minimization Principal and Mountain Pass Theorem.
متن کاملUniversality in eight-arm star polystyrene and methylcyclohexane mixtures near the critical point.
Measurements of the coexistence curve and turbidity were made on different molecular mass samples of the branched polymer-solvent system eight-arm star polystyrene in methylcyclohexane near its critical point. We confirmed that these systems belong in the Ising universality class. The location of the critical temperature and composition as well as the correlation length, susceptibility, and coe...
