Interaction effects in 2D electron gas in a random magnetic field: Implications for composite fermions and quantum critical point
T. A. Sedrakyan, M. E. Raikh
We consider a clean two-dimensional interacting electron gas subject to a random perpendicular magnetic field, h({\bf r}). The field is nonquantizing, in the sense, that {\cal N}_h…
Crossover from weak localization to Shubnikov-de Haas oscillations in a high mobility 2D electron gas
T. A. Sedrakyan, M. E. Raikh
We study the magnetoresistance, δρ_{xx}(B)/ρ_0, of a high-mobility 2D electron gas in the domain of magnetic fields, B, intermediate between the weak localization and the Shubnikov…
Magneto-oscillations due to electron-electron interactions in the ac conductivity of a 2D electron gas
T. A. Sedrakyan, M. E. Raikh
Electron-electron interactions give rise to the correction, δσ^{int}(ω), to the ac magnetoconductivity, σ(ω), of a clean 2D electron gas that is periodic in ω_c^{-1}, where ω_c is…
Zero-bias tunneling anomaly in a clean 2D electron gas caused by smooth density variations
T. A. Sedrakyan, E. G. Mishchenko, M. E. Raikh
We show that smooth variations, δn({\bf r}), of the local electron concentration in a clean 2D electron gas give rise to a zero-bias anomaly in the tunnel density of states, ν(ω),…
