Topological Map of the Hofstadter Butterfly and Van Hove Singularities
Gerardo Naumis, Indubala I. Satija
The Hofstadter butterfly is a quantum fractal with a highly complex nested set of gaps, where each gap represents a quantum Hall state whose quantized conductivity is characterized…
Optical phase shifts and diabolic topology in Mobius-type strips
Indubala I Satija, Radha Balakrishnan
We compute the optical phase shifts between the left and the right-circularly polarized light after it traverses non-planar cyclic paths described by the boundary curves of closed…
Lifshitz-like transition and enhancement of correlations in a rotating bosonic ring lattice
Ana Maria Rey, Keith Burnett, Indubala I. Satija +1
We study the effects of rotation on one-dimensional ultra-cold bosons confined to a ring lattice. For commensurate systems, at a critical value of the rotation frequency, an infini…
Metal-Insulator Transition Revisited for Cold Atoms in Non-Abelian Gauge Potentials
Indubala I. Satija, Daniel C. Dakin, Charles W. Clark
We discuss the possibility of realizing metal-insulator transitions with ultracold atoms in two-dimensional optical lattices in the presence of artificial gauge potentials. Such tr…
Quantum coherence of Hard-Core-Bosons and Fermions : Extended, Glassy and Mott Phases
Ana Maria Rey, Indubala I. Satija, Charles W. Clark
We use Hanbury-Brown-Twiss interferometry (HBTI) to study various quantum phases of hard core bosons (HCBs) and ideal fermions confined in a one-dimensional quasi-periodic (QP) pot…
Noise Correlations of Hard-core Bosons: Quantum Coherence and Symmetry Breaking
Ana Maria Rey, Indubala I Satija, Charles W Clark
Noise correlations, such as those observable in the time of flight images of a released cloud, are calculated for hard-core bosonic (HCB) atoms. We find that the standard mapping o…
