Diagnostics of macroscopic quantum states of Bose-Einstein condensate in double-well potential by nonstationary Josephson effect
E. D. Vol
We propose a method of diagnostic of a degenerate ground state of Bose condensate in a double well potential. The method is based on the study of the one-particle coherent tunnelin…

Metastable bound state of a pair of two-dimensional spatially separated electrons in anti-parallel magnetic fields
S. I. Shevchenko, E. D. Vol
We propose a new mechanism for binding of two equally charged carriers in a double-layer system subjected by a magnetic field of a special form. A field configuration for which the…

Coupling of spatially separated carriers in crossed electric and magnetic fields and a possibility of a metastable superconducting state in bilayer systems
S. I. Shevchenko, E. D. Vol
It is shown that in bilayer conducting structures in crossed electric and magnetic fields of a special configuration (the fields should have opposite signs in the adjacent layers)…
