Bose-Einstein condensation in a decorated lattice: an application to supersolid
D. V. Fil, S. I. Shevchenko
The Bose-Einstein condensation of vacancies in a three-dimensional decorated lattice is considered. The model describes possible scenario of superfluidity of solid helium, caused b…
Non-dissipative drag of superflow in a two-component Bose gas
D. V. Fil, S. I. Shevchenko
A microscopic theory of a non-dissipative drag in a two-component superfluid Bose gas is developed. The expression for the drag current in the system with the components of differe…
Charge ordering and interlayer phase coherence in quantum Hall superlattices
S. I. Shevchenko, D. V. Fil, A. A. Yakovleva
The possibility of the existence of states with a spontaneous interlayer phase coherence in multilayer electron systems in a high perpendicular to the layers magnetic field is inve…
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…
