The energy and equilibrium density of electron-hole liquid in quantum wires is calculated using density functional theory. Nonlinear Schrödinger equations for electrons and holes are solved numerically. It is shown that electron-hole liquid in a quantum wire with a radius of a few exciton radii is stable in semiconductors with single-valley spectrum and isotropic masses of electrons and holes.

量子线中电子-空穴液体的稳定性

使用密度泛函理论计算量子线中电子-空穴液体的能量和平衡密度。对电子和空穴的非线性薛定谔方程进行了数值求解。结果表明，半径为几个激子半径的量子线中的电子空穴液体在具有单谷光谱和各向同性电子和空穴质量的半导体中是稳定的。
