Title: Quantum and spectral properties of the Labyrinth model

Abstract

We consider the Labyrinth model, which is a two-dimensional quasicrystal model. We show that the spectrum of this model, which is known to be a product of two Cantor sets, is an interval for small values of the coupling constant. We also consider the density of states measure of the Labyrinth model and show that it is absolutely continuous with respect to Lebesgue measure for almost all values of coupling constants in the small coupling regime.

  • The authors have carried out a model experiment in the interest of the correction of calculation methods and the computer programs corresponding to them. The passage of the radiation was investigated in a three-section concrete labyrinth specially designed for the purpose, using a spectral recording method which made it possible to carry out a qualitative and quantitative analysis of the laws governing the formation of the energy distribution of the neutron radiation along the labyrinth, as well as a number of functionals of practical importance (the average neutron energy, the specific equivalent dose, the component makeup of the neutron radiation,more » etc.). The plan view of the basic labyrinth is shown; the lining of the first and second turns is made of borated concrete, while on the fragment the lining of the first turn is made of polyethylene. The experimental conditions are described and the neutron spectra were measured at points lying on the geometric axis of the labyrinth. The principal results are shown in tables.« less
  • A zero-field Ising model with ferromagnetic coupling constants on the so-called Labyrinth tiling is investigated. Alternatively, this can be regarded as an Ising model on a square lattice with a quasi-periodic distribution of up to eight different coupling constants. The duality transformation on this tiling is considered and the self-dual couplings are determined. Furthermore, the authors analyze the subclass of exactly solvable models in detail parameterizing the coupling constants in terms of four rapidity parameters. For those, the self-dual couplings correspond to the critical points which, as expected, belong to the Onsager universality class.
  • The spectral linewidth of a GaAlAs double heterostructure laser placed in a high magnetic field is measured at 190 K. It is found that the power-dependent spectral linewidth is reduced by a factor of 0.6 in a magnetic field of 19 T. This reduction is believed to result mainly from the reduction of the linewidth enhancement factor ..alpha.. due to a quasi-one-dimensional electronic system formed by the high magnetic field (i.e., by quantum wire effects).
  • The field spectrum linewidth of a multiple quantum well laser immersed in a high magnetic field is measured at room temperature and at 165 K. The low-temperature measurements show a decrease of linewidth with increasing magnetic field. We believe this behavior results from the formation of a totally discrete electronic state space. Measurements of the low-temperature luminescence spectrum show that the emission is split into two peaks by the high field with the higher energy peak responsible for lasing action.
