    On the Possibility of Superconductivity in Bilayer Heterostructures

    A model is created for bilayer heterostructures in a strong magnetic field which makes it possible to neglect the Coulomb interaction. The thermodynamic instability of states of the electron system in a strong...

    Phase transitions on quantum crystal interfaces

    The quantum solid-on-solid (SOS) model for the free surface of a crystal is studied at zero and finite temperatures. In addition to the usual roughening transition, this model also exhibits a superfluid transi...

    Calculation of the exchange integrals in solid3He

    Calculations are performed for two-, three-, and four-particle exchange in the quantum crystal of bcc solid3He. The quasiclassical approximation is used to find the tunneling path in the space of all atomic coord...

    Magnetic properties of vacancies on the triangular plane 3He crystal

    The ground state of the plane quantum Fermi crystal with a triangular lattice is considered. Using symmetry properties, the ground state wave function is constructed and a variational estimate of the ground st...

    On the relaxation time for nonequilibrium state of superfluid

    The present work deals with the idealized problem of spatially homogeneous flow with different velocity of the normal and superfluid components. The aim of the investigation is the development of the expressio...
