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…
Self-Similarity and Localization
Jukka A. Ketoja, Indubala I. Satija
The localized eigenstates of the Harper equation exhibit universal self-similar fluctuations once the exponentially decaying part of a wave function is factorized out. For a fixed…
Conformal, Subconformal and Spectral Universality in Incommensurate Spin Chains
Jukka A. Ketoja, Indubala I. Satija
A renormalization scheme is developed to study an anisotropic quantum XY spin chain in a quasiperiodic transverse field. The critical phase of the quasi-particle excitations of the…
Decimation Studies of Bloch Electrons in a Magnetic Field: Higher Order Limit Cycles Underlying the Phase Diagram
Jukka A. Ketoja, Indubala I. Satija, Juan Carlos Chaves
A decimation method is applied to the tight binding model describing the two dimensional electron gas with next nearest neighbor interaction in the presence of an inverse golden me…
