Reentrant Phase Diagram of Two-Dimensional Electron Gas
Jukka A. Ketoja, Indubala I. Satija
We study the phase diagram of an electron on a square lattice in a transverse magnetic field. Using a renormalization scheme, we show that the inequality of the two next-nearest ne…

Bloch Electron on a Triangular Lattice and Quantum Ising Model in a Transverse Field
Jukka A. Ketoja, Indubala I. Satija
The tight binding model for an electron on an anisotropic triangular lattice in a uniform magnetic field is studied using a decimation scheme. The model exhibits a transition from…
