Penultimate fate of a dirty-Fermi-liquid
Alexander Punnoose, Alexander M. Finkel'stein
The theory of the dirty-Fermi-liquid which details the destruction of the Fermi-liquid phase up to and including the quantum critical point separating the metallic from the insulat…
Renormalization group study of a two-valley system with spin-splitting
Alexander Punnoose
Renormalization group equations in a two-valley system with valley-splitting and intervalley scattering are derived in the presence of spin-splitting induced by a parallel magnetic…
Test of scaling theory in two dimensions in the presence of valley splitting and intervalley scattering in Si-MOSFETs
A. Punnoose, A. M. Finkel'stein, A. Mokashi +1
We show that once the effects of valley splitting and intervalley scattering are incorporated, renormalization group theory consistently describes the metallic phase in silicon met…
Renormalization group study of intervalley scattering and valley splitting in a two-valley system
Alexander Punnoose
Renormalization group equations are derived for the case when both valley splitting and intervalley scattering are present in a two-valley system. A third scaling parameter is show…
Magnetoconductivity in the presence of Bychkov-Rashba spin-orbit interaction
Alexander Punnoose
A closed-form analytic formula for the magnetoconductivity in the diffusive regime is derived in the presence of Bychkov-Rashba spin-orbit interaction in two dimensions. It is show…
Spin relaxation in the presence of electron-electron interactions
Alexander Punnoose, Alexander M. Finkel'stein
The D'yakonov-Perel' spin relaxation induced by the spin-orbit interaction is examined in disordered two-dimensional electron gas. It is shown that, because of the electron-electro…
Metal-Insulator Transition in Disordered Two-Dimensional Electron Systems
Alexander Punnoose, Alexander M. Finkel'stein
We present a theory of the metal-insulator transition in a disordered two-dimensional electron gas. A quantum critical point, separating the metallic phase which is stabilized by e…
Dilute electron gas near the metal-insulator transition in two dimensions
Alexander Punnoose, Alexander M. Finkel'stein
In recent years systematic experimental studies of the temperature dependence of the resistivity in a variety of dilute, ultra clean two dimensional electron/hole systems have revi…
