On Anderson Localisation of Two-Dimensional Electrons in Weak Magnetic Field (2005)
The two-parameter renormalization group flow diagramme is used for obtaining the magnetic field dependence of localisation length Lc(B) for charged particles in 2D random potential at low disorder...

Level statistics in a two-dimensional disc with diffusive boundary scattering (1998)
Tripathi, V., Khmelnitskii, D. E.
We calculate the energy level statistics in a two-dimensional disc with diffusive boundary scattering by the means of the recently proposed ballistic nonlinear sigma-model.
Anomalous Thermal Transport in Quantum Wires (1997)
Fazio, Rosario, Hekking, F. W. J., Khmelnitskii, D. E.
We study thermal transport in a one-dimensional quantum wire, connected to reservoirs. Despite of the absence of electron backscattering, interactions in the wire strongly influence thermal...
A Renormalization-Group approach to the Coulomb Gap (1996)
Johnson, S. R., Khmelnitskii, D. E.
The free energy of the Coulomb Gap problem is expanded as a set of Feynman diagrams, using the standard diagrammatic methods of perturbation theory. The gap in the one-particle density of states due...
Nearly Localised States in Weakly Disordered Conductors. II. Beyond Diffusion Approximation (1996)
Muzykantskii, B. A., Khmelnitskii, D. E.
We use optimal fluctuation method for a new ballistic $\sigma$-model to study the long time dispersion of conductance $G(t)$ of a mesoscopic sample. In the long time limit the conductance of a...
Effective Action in Theory of Quasi-Ballistic Disordered Conductors (1995)
Muzykantskii, B. A., Khmelnitskii, D. E.
We suggest an effective field theory for disorderd conductors, which describes quantum kinetics of ballistically propagating electrons. This theory contains non-linear $\sigma$-model \cite{Efetov} as...
