Quantum critical behavior in the Kondo problem with a pseudogap
Kevin Ingersent, Qimiao Si
The variant of the single-impurity Kondo problem in which the conduction-band density of states has a power-law pseudogap at the Fermi energy is known to exhibit a zero-temperature…

Metal-Insulator Transition of Disordered Interacting Electrons
Qimiao Si, C. M. Varma
We calculate the corrections to the conductivity and compressibility of a disordered metal when the mean free path is smaller than the screening length. Such a condition is shown t…

Spin Injection into a Luttinger Liquid
Qimiao Si
We study the effect of spin injection into a Luttinger liquid. The spin-injection-detection setup of Johnson and Silsbee is considered; here spins injected into the Luttinger liqui…
