Journal ArticleDOI
Temperature and Purity Dependence of the Superconducting Critical Field, H c 2 . III. Electron Spin and Spin-Orbit Effects
TL;DR: In this paper, a solution of the linearized Gor'kov equations for the upper critical magnetic field of a bulk type-II superconductor is extended to include the effects of Pauli spin paramagnetism and spin-orbit impurity scattering.
Journal ArticleDOI
Fluctuation effects in the theory of microphase separation in block copolymers
TL;DR: In this paper, the effect of composition fluctuations on the microphase separation transition in diblock copolymers is investigated, and the analysis is facilitated by reducing the block copolymer Hamiltonian to a form previously studied by Brazovskii.
Journal ArticleDOI
Theory of the Interface between Immiscible Polymers. II
Eugene Helfand,Yukiko Tagami +1 more
TL;DR: In this paper, a selfconsistent field approach is employed to describe the configurational statistics of polymer molecules in the interfacial region, and the density profiles and surface tension are calculated, and compare well with experiments.
Journal ArticleDOI
Temperature and Purity Dependence of the Superconducting Critical Field, H c 2 . II
Eugene Helfand,N. R. Werthamer +1 more
TL;DR: In this paper, a rigorous solution of the linearized Gor'kov equations is presented, yielding the complete temperature and electron-mean-free-path dependences of the upper critical magnetic field of a bulk type-II superconductor.
Journal ArticleDOI
Scaled Particle Theory of Fluid Mixtures
TL;DR: An extension of a previous one component theory of hard-sphere systems and the surface tension of real systems is made to mixtures in this article, based on consideration of an approximate expression for the work of adding an additional hard sphere to a mixture.
