Spin Polarization Dependence of Carrier Effective Mass in Semiconductor Structures: Spintronic Effective Mass
Ying Zhang, S. Das Sarma
We introduce the concept of a spintronic effective mass for spin-polarized carriers in semiconductor structures, which arises from the strong spin-polarization dependence of the re…
Temperature and magnetization-dependent band-gap renormalization and optical many-body effects in diluted magnetic semiconductors
Ying Zhang, S. Das Sarma
We calculate the Coulomb interaction induced density, temperature and magnetization dependent many-body band-gap renormalization in a typical diluted magnetic semiconductor GaMnAs…
Exchange instabilities in electron systems: Bloch versus Stoner Ferromagnetism
Ying Zhang, S. Das Sarma
We show that 2D and 3D electron systems with the long-range Coulomb electron-electron interaction could develop ferromagnetic instabilities due to strong exchange effects at low de…
Dispersion Instability in Strongly Interacting Electron Liquids
Ying Zhang, V. M. Yakovenko, S. Das Sarma
We show that the low-density strongly interacting electron liquid, interacting via the long-range Coulomb interaction, could develop a dispersion instability at a critical density…
Density dependent spin susceptibility and effective mass in interacting quasi-two dimensional electron systems
Ying Zhang, S. Das Sarma
Motivated by recent experimental reports, we carry out a Fermi liquid many-body calculation of the interaction induced renormalization of the spin susceptibility and effective mass…
Temperature dependent effective mass renormalization in a Coulomb Fermi liquid
Ying Zhang, S. Das Sarma
We calculate numerically the quasiparticle effective mass (m*) renormalization as a function of temperature and electron density in two- and three-dimensional electron systems with…
