Longitudinal Josephson effect in systems with pairing of spatially separated electrons and holes
S. I. Shevchenko, O. M. Konstantynov
Longitudinal non-dissipative current states in bilayer electron-hole systems in the presence of potential barriers that divide the system into left and right sides was investigated…
Stationary waves in a superfluid gas of electron-hole pairs in bilayers
D. V. Fil, S. I. Shevchenko
Stationary waves in the condensate of electron-hole pairs in the bilayer system are studied. The system demonstrates the transition from a uniform (superfluid) to a nonunifor…
Transition to a supersolid phase in a two-dimensional dilute gas of electron-hole pairs
D. V. Fil, S. I. Shevchenko
Using coherent-state formalism (the Keldysh formalism), the article describes a transition from a homogeneous superfluid state to a supersolid state in a two-dimensional dilute gas…
Superfluidity of a rarefied gas of electron-hole pairs in a bilayer system
D. V. Fil, S. I. Shevchenko
The conditions of stability of the superfluid phase in double layer systems with pairing of spatially separated electrons and holes in the low density limit are studied. The genera…
Superfluidity of electron-hole pairs in randomly inhomogeneous bilayer systems
A. I. Bezuglyj, S. I. Shevchenko
In bilayer systems electron-hole (e-h) pairs with spatially separated components (i.e., with electrons in one layer and holes in the other) can be condensed to a superfluid state w…
Dynamic equation for quantum Hall bilayers with spontaneous interlayer coherence: The low-density limit
A. I. Bezuglyj, S. I. Shevchenko
The bilayer systems exhibit the Bose-Einstein condensation of excitons that emerge due to Coulomb pairing of electrons belonging to one layer with the holes belonging to the other…
Josephson vortex motion as a source for dissipation of superflow of e-h pairs in bilayers
D. V. Fil, S. I. Shevchenko
IIt is shown that in a bilayer excitonic superconductor dissipative losses emerge under transmission of the current from the source to the load. These losses are proportional to th…
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…
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…
Charged vortices in superfluid systems with pairing of spatially separated carriers
S. I. Shevchenko
It is shown that in a magnetic field the vortices in superfluid electron-hole systems carry a real electrical charge. The charge value depends on the relation between the magnetic…
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)…
