  • Extending the geometry of heterotic spectral cover constructions 

    Anderson, Lara B.; Gao, Xin; Karkheiran, Mohsen (2020-07)
    In this work we extend the well-known spectral cover construction first developed by Friedman, Morgan, and Witten to describe more general vector bundles on elliptically fibered Calabi-Yau geometries. In particular, we ...
  • Precise high-fidelity electron-nuclear spin entangling gates in NV centers via hybrid dynamical decoupling sequences 

    Dong, Wenzheng; Calderon-Vargas, F. A.; Economou, Sophia E. (2020-07)
    Color centers in solids, such as the nitrogen-vacancy center in diamond, offer well-protected and well-controlled localized electron spins that can be employed in various quantum technologies. Moreover, the long coherence ...
  • Parallel Temperature Interfaces in the Katz-Lebowitz-Spohn Driven Lattice Gas 

    Mukhamadiarov, Ruslan I.; Priyanka; Täuber, Uwe C.
    We explore a variant of the Katz-Lebowitz-Spohn (KLS) driven lattice gas in two dimensions, where the lattice is split into two regions that are coupled to heat baths with distinct temperatures. The temperature boundaries ...
  • Social distancing and epidemic resurgence in agent-based Susceptible-Infectious-Recovered models 

    Mukhamadiarov, Ruslan I.; Deng, Shengfeng; Serrao, Shannon R.; Priyanka; Nandi, Riya; Yao, Louie Hong; Täuber, Uwe C.
    Once an epidemic outbreak has been effectively contained through non-pharmaceutical interventions, a safe protocol is required for the subsequent release of social distancing restrictions to prevent a disastrous resurgence ...
  • Coupled two-species model for the pair contact process with diffusion 

    Deng, S.; Li, W.; Täuber, Uwe C. (American Physical Society (APS), 2020-10-22)
    The contact process with diffusion (PCPD) defined by the binary reactions B+B→B+B+B, B+B→∅ and diffusive particle spreading exhibits an unusual active to absorbing phase transition whose universality class has long been ...
  • Critical dynamics of anisotropic antiferromagnets in an external field 

    Nandi, Riya; Täuber, Uwe C. (American Physical Society (APS), 2020-03-03)
    We numerically investigate the non-equilibrium critical dynamics in three-dimensional anisotropic antiferromagnets in the presence of an external magnetic field. The phase diagram of this system exhibits two critical lines ...
  • Structural, in silico, and functional analysis of a Disabled-2-derived peptide for recognition of sulfatides 

    Song, Wei; Gottschalk, Carter J.; Tang, Tuo-Xian; Biscardi, Andrew; Ellena, Jeffrey F.; Finkielstein, Carla, V; Brown, Anne M.; Capelluto, Daniel G. S. (2020-08-11)
    Disabled-2 (Dab2) is an adaptor protein that regulates the extent of platelet aggregation by two mechanisms. In the first mechanism, Dab2 intracellularly downregulates the integrin alpha (IIb)beta (3) receptor, converting ...
  • Higgs inflation, vacuum stability, and leptogenesis 

    Barrie, Neil D.; Sugamoto, Akio; Takeuchi, Tatsu; Yamashita, Kimiko (2020-08-17)
    We consider the introduction of a complex scalar field carrying a global lepton number charge to the Standard Model and the Higgs inflation framework. The conditions are investigated under which this model can simultaneously ...
  • New constraints on heavy neutral leptons from Super-Kamiokande data 

    Coloma, P.; Hernandez, P.; Munoz, V.; Shoemaker, I. M. (2020-03-12)
    Heavy neutral leptons are predicted in many extensions of the Standard Model with massive neutrinos. If kinematically accessible, they can be copiously produced from kaon and pion decays in atmospheric showers, and ...
  • Modular curves and Mordell-Weil torsion in F-theory 

    Hajouji, Nadir; Oehlmann, Paul-Konstantin (2020-04-16)
    In this work we prove a bound for the torsion in Mordell-Weil groups of smooth elliptically fibered Calabi-Yau 3- and 4-folds. In particular, we show that the set of torsion groups which can occur on a smooth elliptic ...
  • Numerical metrics, curvature expansions and Calabi-Yau manifolds 

    Cui, Wei; Gray, James (2020-05-11)
    We discuss the extent to which numerical techniques for computing approximations to Ricci-flat metrics can be used to investigate hierarchies of curvature scales on Calabi-Yau manifolds. Control of such hierarchies is ...
  • Exploring optimization strategies for improving explicit water models: Rigid n-point model and polarizable model based on Drude oscillator 

    Xiong, Yeyue; Onufriev, Alexey V. (PLOS, 2019-11-14)
    Rigid n-point water models are widely used in atomistic simulations, but have known accuracy drawbacks. Increasing the number of point charges, as well as adding electronic polarizability, are two common strategies for ...

    Heisenberg exchange coupling between neighboring electron spins in semiconductor quantum dots provides a powerful tool for quantum information processing and simulation. Although so far unrealized, extended Heisenberg spin ...
