Superconducting system with weak coupling to the current in the ground state
We consider a superconducting ring with a Josephson junction containing magnetic impurities. It is shown that if the tunneling through the magnetic impurities is large enough, then the ground stateExpand

Comments on the region of applicability of the landau theory for structural phase transitions
The Landau theory of phase transitions1 is known to ignore (in its main approximation) long-wave fluctuations of the order parameter. In this aspect this theory is equivalent to the theory of theExpand

On possibility of the spontaneous magnetic flux in a Josephson junction containing magnetic impurities
Abstract The Josephson junction containing localized magnetic moments in a dielectric layer between two superconductors is considered. Conditions are studied under which the phase difference betweenExpand

Superconducting properties of systems with local pairs
An analysis is made of the superconducting properties of systems with a strong electron attraction at one center in the limit when such attraction is strong compared with the energy band width. ThisExpand

On the theory of superfluidity of helium II near the λ point
The present state of the Ψ theory of superfluidity of helium II near the λ point is reviewed. The basic assumptions underlying this theory and the limits of its applicability are discussed. TheExpand

Superfluidity of helium II near the λ point
The properties (and particularly the superfluidity) of liquid helium near the λ point have long been and still are objects of numerous investigations. Nonetheless, much of the problem remainsExpand

Light scattering near phase transition points in solids
Abstract The present state of theoretical and experimental investigations of the light scattering near phase transition points in solids is reviewed. It is emphasized that the results available hereExpand
