Drag of superfluid current in bilayer Bose systems
D. V. Fil, S. I. Shevchenko
An effect of nondissipative drag of a superfluid flow in a system of two Bose gases confined in two parallel quasi two-dimensional traps is studied. Using an approach based on intr…

Order parameter phase locking as a cause of a zero bias peak in the differential tunneling conductance of bilayers with electron-hole pairing
A. I. Bezuglyj, S. I. Shevchenko
In n-p bilayer systems an exotic phase-coherent state emerges due to Coulomb pairing of n-layer electrons with p-layer holes. Unlike Josephson junctions, the order parameter phase…

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…
