We present details of earlier studies [Zheng et al., Phys. Rev. Lett. 78, 310 (1997) and Das
Sarma et al., 79, 917 (1997)] and additional results on double-layer quantum Hall systems at …

We investigate the instability of layer pseudospin paramagnetic (PSP) state to the formation
of pseudospin density wave (PSDW) in two-dimensional (2D) electron bilayers, analogous …

We study intersubband spin density collective modes in double-layer quantum Hall systems
at ν= 2 within the time-dependent Hartree-Fock approximation. We find that these …

We theoretically consider bilayers of two-dimensional (2D) electron gases as in
semiconductor quantum wells, and investigate possible spontaneous symmetry breaking …

We consider various exchange-driven electronic instabilities in semiconductor double-layer
systems in the absence of any external magnetic field. We establish that there is no …

We study the magnetoplasmon collective-mode excitations of integer quantum Hall systems
in a parabolically confined quantum well nanostructure in the presence of a tilted magnetic …

We search for the uniform Hartree-Fock ground state of the two-dimensional electron gas
formed in semiconductor heterostructures including the Rashba spin-orbit interaction. We …

We examine the robustness of a recently predicted exchange-induced zero-field magnetic
phase in semiconductor double quantum wells in which each well is spin polarized and the …
