Topology Induced Oscillations in Majorana Fermions in a Quasiperiodic Superconducting Chain
Indubala I Satija
Spatial profile of the Majorana fermion wave function in a one-dimensional -wave superconductors () with quasi periodic disorder is shown to exhibit spatial oscillati…
Topology and Self-Similarity of the Hofstadter Butterfly
Indubala Satija
We revisit the problem of self-similar properties of the Hofstadter butterfly spectrum, focusing on spectral as well as topological characteristics. In our studies involving any va…
Hidden Quasicrystal in Hofstadter Butterfly
Indubala I Satija
Topological description of hierarchical sets of spectral gaps of Hofstadter butterfly is found to be encoded in a quasicrystal where magnetic flux plays the role of a phase factor…
Supermetallic and Trapped States in Periodically Kicked Lattices
Indubala I Satija, Bala Sundaram
A periodically driven lattice with two commensurate spatial periodicities is found to exhibit super metallic states characterized by enhancements in wave packet spreading and entro…
Non-hermiticity in a kicked model: Decoherence and the semiclassical limit
Indubala I satija, Arjendu Pattanayak
We study the effects of non-hermitian perturbation on a quantum kicked model exhibiting a localization transition. Using an exact renormalization scheme, we show that the critical…
Localization, Dirac Fermions and Onsager Universality
Indubala I. Satija
Disordered systems exhibiting exponential localization are mapped to anisotropic spin chains with localization length being related to the anisotropy of the spin model. This relate…
Localization Characteristics of Relativistic vs Nonrelativistic Fermions on a Lattice
Indubala I Satija
Relativistic fermions on a lattice are shown to correspond to the in the localized nonrelativistic fermions. Therefore, in contrast to nonrelativistic case, the rela…
Localization Transition in Incommensurate non-Hermitian Systems
Amin Jazaeri, Indubala I. Satija
A class of one-dimensional lattice models with incommensurate complex potential is found to exhibit localization transition at . Th…
Hidden Dimer in the Frenkel-Kontorova model
Jukka A. Ketoja, Indubala I. Satija
The incommensurability of the supercritical Frenkel-Kontorova model is decomposed into a family of dimer type "defects" by appropriate decimations. Interestingly, this hidden dimer…
