Bbranes and supersymmetric quivers in 2d
(Springer, 20180208)We study 2d N = (0, 2) supersymmetric quiver gauge theories that describe the lowenergy dynamics of D1branes at CalabiYau fourfold (CY4) singularities. On general grounds, the holomorphic sector of these theories  ... 
Background independent quantum mechanics and gravity
(American Physical Society, 20030915)We argue that the demand of background independence in a quantum theory of gravity calls for an extension of standard geometric quantum mechanics. We discuss a possible kinematical and dynamical generalization of the latter ... 
BAL outflow contribution to AGN feedback: frequency of S IV outflows in the SDSS
(IOP Publishing Ltd., 201205)We present a study of broad absorption line (BAL) quasar outflows that show S IV lambda 1063 and S IV* lambda 1073 troughs. The fractional abundances of S IV and C IV peak at similar value of the ionization parameter, ... 
BAL phosphorus abundance and evidence for immense ionic column densities in quasar outflows: vlt/xshooter observations of quasar SDSS J1512+1119
(IOP Publishing Ltd., 201210)We present spectroscopic analysis of the broad absorption line (BAL) outflow in quasar SDSS J1512+1119. In particular, we focus our attention on a kinematic component in which we identify P V and S IV/S IV* absorption ... 
Bell's Inequalities, Superquantum Correlations, and String Theory
(Hindawi Publishing Corporation, 2011)We offer an interpretation of superquantum correlations in terms of a “doubly” quantum theory.We argue that string theory, viewed as a quantum theory with two deformation parameters, the string tension α', and the string ... 
Bell's Inequalities, Superquantum Correlations, and String Theory
(Hindawi Publishing Corporation, 20110101)We offer an interpretation of superquantum correlations in terms of a “doubly” quantum theory. We argue that string theory, viewed as a quantum theory with two deformation parameters, the string tension a′ and the string ... 
Biorthogonal quantum mechanics: superquantum correlations and expectation values without definite probabilities
(Iop Publishing Ltd, 20131206)We propose mutant versions of quantum mechanics constructed on vector spaces over the finite Galois fields GF(3) and GF(9). The mutation we consider here is distinct from what we proposed in previous papers on Galois field ... 
Bistability in an Ising model with nonHamiltonian dynamics
(American Physical Society, 199203)We investigate the phenomenon of magnetization bistability in a twodimensional Ising model with a nonHamiltonian Glauber dynamics by means of Monte Carlo simulations. This effect has previously been observed in the Toom ... 
BohmAharonov experiment without an electron microscope
(American Physical Society, 197808)A newtype BohmAharonov experiment is proposed. The experiment can be carried out in a large scale without the help of an electron microscope.

Boson core compressibility
(American Physical Society, 20120416)Strongly interacting atoms trapped in optical lattices can be used to explore phase diagrams of Hubbard models. Spatial inhomogeneity due to trapping typically obscures distinguishing observables. We propose that measures ... 
Bound states of hydrogen atom in a theory with minimal length uncertainty relations
(AIP Publishing, 200705)The following properties of bound states of hydrogen atom in a theory with noncommuting position operators are investigated: their number, multiplicities, accidental degeneracy, localization, and dependence on the values ... 
Boundary Effects on Population Dynamics in Stochastic Lattice LotkaVolterra Models
We investigate spatially inhomogeneous versions of the stochastic LotkaVolterra model for predatorprey competition and coexistence by means of Monte Carlo simulations on a twodimensional lattice with periodic boundary ... 
Bounds on cosmic rayboosted dark matter in simplified models and its corresponding neutrinofloor
(20200615)We study direct detection bounds on cosmic rayupscattered dark matter in simplified models including light mediators. We find that the energy dependence in the scattering cross section is significant, and produces stronger ... 
Breathing dynamics in heteropolymer DNA
(CELL PRESS, 200704)While the statistical mechanical description of DNA has a long tradition, renewed interest in DNA melting from a physics perspective is nourished by measurements of the fluctuation dynamics of local denaturation bubbles ... 
A CalabiYau database: threefolds constructed from the KreuzerSkarke list
(Springer, 20150225)Kreuzer and Skarke famously produced the largest known database of CalabiYau threefolds by providing a complete construction of all 473,800,776 reflexive polyhedra that exist in four dimensions [1]. These polyhedra describe ... 
CALIS  A CALibration Insertion System for the DarkSide50 dark matter search experiment
(201712)This paper describes the design, fabrication, commissioning and use of a CALibration source Insertion System (CALIS) in the DarkSide50 direct dark matter search experiment. CALIS deploys radioactive sources into the liquid ... 
Can we make the SiCSiO2 interface as good as the SiSiO2 interface?
(AIP Publishing, 200110)A simple analysis based on the bulk valence and conduction densities of states was employed to estimate the interfacestate densities for interfaces between the three most common SiC polytypes (3C, 4H, and 6H) and SiO2. ... 
Canine Cancer Screening Via Ultraviolet Absorbance And Fluorescence Spectroscopy Of Serum Proteins
(Optical Society of America, 20070101)A costeffective optical cancer screening and monitoring technique was demonstrated in a pilot study of canine serum samples and was patented for commercialization. Compared to conventional blood chemistry analysis methods, ... 
Capillary adhesion at the nanometer scale.
(201406)Molecular dynamics simulations are used to study the capillary adhesion from a nonvolatile liquid meniscus between a spherical tip and a flat substrate. The atomic structure of the tip, the tip radius, the contact angles ...
