Hofstadter spectrum in electric and magnetic fields
The problem of Bloch electrons in two dimensions subject to magnetic and intense electric fields is investigated. Magnetic translations, electric evolution and energy translation operators are used to specify the solutions of the Schrödinger equation. For rational values of the magnetic flux quanta per unit cell and commensurate orientations of the electric field relative to the original lattic...
متن کاملMagnetic Fingerprints of Fractal Spectra and Duality of Hofstadter Models
We study the de-Haas van Alphen oscillations in the magnetization of the Hofstadter model. Near a split band the magnetization is a rapidly oscillations function of the Fermi energy with lip shaped envelopes. For generic magnetic fields this structure appears on all scales and provides a thermodynamic fingerprint of the fractal properties of the model. The analysis applies equally well to the t...
متن کاملEffective magnetic fields in graphene superlattices.
We demonstrate that the electronic spectrum of graphene in a one-dimensional periodic potential will develop a Landau level spectrum when the potential magnitude varies slowly in space. The effect is related to extra Dirac points generated by the potential whose positions are sensitive to its magnitude. We exploit a chiral symmetry in the Dirac Hamiltonian description with a superlattice potent...
متن کاملLarge magnetoresistance with low saturation fields in magnetic/magnetic superlattices
Ni/Co multilayers grown by molecular beam epitaxy are found to exhibit a magnetoresistance AR/R at liquid helium temperature as large as 8.2%, with saturation fields AH-22 Oe and a sensitivity (AR/R)/(2AH)=O. 19% Oe-‘. The highest room temperature sensitivity obtained to date in this system is 0.18% Oe-’ and at 4.2 K is 0.29% Oe-‘. This demonstrates that high values of the sensitivity can be ac...
متن کاملTime-periodic behavior of multiband superlattices in static electric fields.
We use an analytic perturbation expansion for the two-band system of tight binding electrons to discuss Bloch oscillations and Zener tunneling within this model. We make comparison with recent numerical results and predict analytically the frequency of radiation expected from Zener tunneling, including its disappearance, as a function of the system parameters. PACS numbers: 71.70.Ej, 73.40.Gk, ...
