    • Anderson localization for quasi-periodic CMV matrices and quantum walks 

      Wang, Fengpeng; Damanik, David (2019)
      We consider CMV matrices, both standard and extended, with analytic quasi-periodic Verblunsky coefficients and prove Anderson localization in the regime of positive Lyapunov exponents. This establishes the CMV analog of a result Bourgain and Goldstein proved for discrete one-dimensional Schrödinger operators. We also prove a similar result for quantum ...
    • Anderson localization for radial tree graphs with random branching numbers 

      Damanik, David; Sukhtaiev, Selim (2019)
      We prove Anderson localization for the discrete Laplace operator on radial tree graphs with random branching numbers. Our method relies on the representation of the Laplace operator as the direct sum of half-lineᅠJacobi matricesᅠwhose entries are non-degenerate, independent, identically distributed random variables with singular distributions.
    • Cooling and instabilities in colliding flows 

      Markwick, R.N.; Frank, A.; Carroll-Nellenback, J.; Liu, B.; Blackman, E.G.; (2021)
      Collisional self-interactions occurring in protostellar jets give rise to strong shocks, the structure of which can be affected by radiative cooling within the flow. To study such colliding flows, we use the AstroBEAR AMR code to conduct hydrodynamic simulations in both one and three dimensions with a power-law cooling function. The characteristic ...
    • Limit-periodic Schrödinger operators with Lipschitz continuous IDS 

      Damanik, David; Fillman, Jake (2019)
      We show that there exist limit-periodic Schrödinger operators such that the associated integrated density of states is Lipschitz continuous. These operators arise in the inverse spectral theoretic KAM approach of Pöschel.
    • Multidimensional Almost-Periodic Schrödinger Operators with Cantor Spectrum 

      Damanik, David; Fillman, Jake; Gorodetski, Anton (2019)
      We construct multidimensional almost-periodic Schrödinger operators whose spectrum has zero lower box-counting dimension. In particular, the spectrum in these cases is a generalized Cantor set of zero Lebesgue measure.
    • Relational Segregation: A Structural View of Categorical Relations 

      Fiel, Jeremy E. (2021)
      This article builds a framework for a relational approach to segregation that emphasizes structures of interactions, transactions, and ties between and within social categories. Rather than explaining segregation with dominants imposing formal rules or homophilic people sorting themselves, I highlight segregation's emergence amid dueling control ...
    • The Electronic Vesalius: Embodying Anatomy Atlases 

      Mulligan, John; Wettergreen, Matthew; Jin, Ying; Rasich, Benjamin; Phillips, Isaac (2018)
      A multidisciplinary team at Rice University transformed the Texas Medical Center (TMC) Library’s collection of rare anatomy atlases into a physical-digital, human-sized atlas-of-atlases. The Electronic Vesalius installation gives these old books new life, informed by contemporary media theory and the centuries of medical and aesthetic criticism ...
