Extending the geometry of heterotic spectral cover constructions
(202007)In this work we extend the wellknown spectral cover construction first developed by Friedman, Morgan, and Witten to describe more general vector bundles on elliptically fibered CalabiYau geometries. In particular, we ... 
Precise highfidelity electronnuclear spin entangling gates in NV centers via hybrid dynamical decoupling sequences
(202007)Color centers in solids, such as the nitrogenvacancy center in diamond, offer wellprotected and wellcontrolled localized electron spins that can be employed in various quantum technologies. Moreover, the long coherence ... 
Parallel Temperature Interfaces in the KatzLebowitzSpohn Driven Lattice Gas
We explore a variant of the KatzLebowitzSpohn (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 agentbased SusceptibleInfectiousRecovered models
Once an epidemic outbreak has been effectively contained through nonpharmaceutical interventions, a safe protocol is required for the subsequent release of social distancing restrictions to prevent a disastrous resurgence ... 
Coupled twospecies model for the pair contact process with diffusion
(American Physical Society (APS), 20201022)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
(American Physical Society (APS), 20200303)We numerically investigate the nonequilibrium critical dynamics in threedimensional 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 Disabled2derived peptide for recognition of sulfatides
(20200811)Disabled2 (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
(20200817)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 SuperKamiokande data
(20200312)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 MordellWeil torsion in Ftheory
(20200416)In this work we prove a bound for the torsion in MordellWeil groups of smooth elliptically fibered CalabiYau 3 and 4folds. In particular, we show that the set of torsion groups which can occur on a smooth elliptic ... 
Numerical metrics, curvature expansions and CalabiYau manifolds
(20200511)We discuss the extent to which numerical techniques for computing approximations to Ricciflat metrics can be used to investigate hierarchies of curvature scales on CalabiYau manifolds. Control of such hierarchies is ... 
Exploring optimization strategies for improving explicit water models: Rigid npoint model and polarizable model based on Drude oscillator
(PLOS, 20191114)Rigid npoint 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 ... 
Coherent Multispin Exchange Coupling in a QuantumDot Spin Chain
(20200708)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 ...

Center for Soft Matter and Biological Physics Symposium Scientific Program 2016
(Virginia Tech. Center for Soft Matter and Biological Physics, 20160519)A program from the symposium held on May 19, 2016, in Hahn North 130. 
Reflections on the anomalous ANITA events: the Antarctic subsurface as a possible explanation
(Cambridge University Press, 20200330)The Antarctic Impulsive Transient Antenna (ANITA) balloon experiment was designed to detect radio signals initiated by highenergy neutrinos and cosmic ray (CR) air showers. These signals are typically discriminated by the ... 
Nonequilibrium signal integration in hydrogels
(20200120)Materials that perform complex chemical signal processing are ubiquitous in living systems. Their synthetic analogs would transform developments in biomedicine, catalysis, and many other areas. By drawing inspiration from ... 
Efficient symmetrypreserving state preparation circuits for the variational quantum eigensolver algorithm
(20200128)The variational quantum eigensolver is one of the most promising approaches for performing chemistry simulations using noisy intermediatescale quantum (NISQ) processors. The efficiency of this algorithm depends crucially ... 
Constraints on flavordiagonal nonstandard neutrino interactions from Borexino PhaseII
(20200205)The Borexino detector measures solar neutrino fluxes via neutrinoelectron elastic scattering. Observed spectra are determined by the solarnu(e) survival probability Pee(E), and the chiral couplings of the neutrino and ...
