  • Skyrmion Solutions to the Weinberg-Salam Model 
    Eilam, G.; Klabucar, D.; Stern, Allen (1986-03-31)
  • Frozen Solitons in a Two-Dimensional Ferromagnet 
    Stern, Allen (1987-10-05)
    The fundamental soliton solution of the O(3) nonlinear σ model in two space dimensions is examined. It is pointed out that the classical soliton is associated with an infinite moment of inertia and infinite moment of ...
  • Lorentzian Fuzzy Spheres 
    Chaney, A.; Lu, Lei; Stern, Allen (2015-09-16)
    We show that fuzzy spheres are solutions of Lorentzian Ishibashi-Kawai-Kitazawa-Tsuchiya-type matrix models. The solutions serve as toy models of closed noncommutative cosmologies where big bang/crunch singularities appear ...
  • Matrix Model Cosmology in Two Space-Time Dimensions 
    Stern, Allen (2014-12-18)
    We examine solutions to the classical Ishibashi-Kawai-Kitazawa-Tsuchiya matrix model equations in three space-time dimensions. Closed, open and static two-dimensional universes naturally emerge from such models in the ...
  • Location and Direction Dependent Effects in Collider Physics from Noncommutativity 
    Haghighat, Mansour; Okada, Nobuchika; Stern, Allen (2010-06-28)
    We examine the leading order noncommutative corrections to the differential and total cross sections for e+ e− → qq‾. After averaging over the Earth’s rotation, the results depend on the latitude for the collider, as well ...
  • SUq(2) Lattice Gauge Theory 
    Bimonte, G.; Stern, Allen; Vitale, P. (1996-07-01)
    We reformulate the Hamiltonian approach to lattice gauge theories such that, at the classical level, the gauge group does not act canonically, but instead as a Poisson-Lie group. At the quantum level, the symmetry gets ...
  • Bosonic Description of Spinning Strings in 2 + 1 Dimensions 
    Harms, B.; Stern, Allen (1996-09-15)
    We write down a general action principle for spinning strings in (2+1)-dimensional space-time without introducing Grassmann variables. The action is written solely in terms of coordinates taking values in the 2+1 Poincaré ...
  • Noncommunicative Static Strings from Matrix Models 
    Stern, Allen (2014-05-23)
    We examine the noncommutative cylinder solution to a matrix model with a Minkowski background metric. It can be regarded as the noncommutative analogue of a static circular string. Perturbations about the solution yield a ...
  • Deformed Wong Particles 
    Stern, Allen; Yakushin, I. (1993-11-15)
    By generalizing the Feynman proof of the Lorentz force law, recently reported by Dyson, we derive equations of motion for particles possessing internal degrees of freedom Ia which do not, in general, generate a finite ...
  • Statistics of Spinning Particles in 2 + 1 Gravity 
    Gupta, K.; Stern, Allen (1991-10-15)
    We examine the dynamics of N spinning particles in 2+ 1 gravity, and obtain an effective Lagrangian description for the particles by eliminating the dreibeins and spin connections from the theory. The resulting equations ...
  • General Coupling of Strings to the Low-Energy Effective Theory 
    Salomonson, P.; Skagerstam, B. -S.; Stern, Allen (1988-06-15)
    Starting from the field equations for supergravity coupled to super-Yang-Mills theory, we derive the classical equations of motion for spinning strings in an arbitrary background. These equations are also obtained from ...
  • Matrix Model Approach to Cosmology 
    Chaney, A.; Lu, Lei; Stern, Allen (American Physical Society, 2016-03)
    We perform a systematic search for rotationally invariant cosmological solutions to toy matrix models. These models correspond to the bosonic sector of Lorentzian Ishibashi, Kawai, Kitazawa and Tsuchiya (IKKT)-type matrix ...
  • Fuzzy CP2 Spacetimes 
    Chaney, A.; Stern, Allen (American Physical Society, 2017-02)
    Four-dimensional manifolds with changing signature are obtained by taking the large N limit of fuzzy CP2 solutions to a Lorentzian matrix model. The regions of Lorentzian signature give toy models of closed universes which ...
  • Signature Change in Matrix Model Solutions 
    Stern, Allen; Xu, Chuang (American Physical Society, 2018-10)
    Various classical solutions to lower dimensional Ishibashi-Kawai-Kitazawa-Tsuchiya–like Lorentzian matrix models are examined in their commutative limit. Poisson manifolds emerge in this limit, and their associated induced ...
  • Integrating Game-Based Learning Initiative: Increasing the Usage of Game-Based Learning Within K-12 Classrooms Through Professional Learning Groups 
    Denham, André R.; Mayben, Robert; Boman, Terri (Springer, 2016-01)
    In the past 15 to 20 years there has been an increased interest in the use of games for learning. A considerable amount of work has already been done by educational researchers and theorists (Gee, Squire, Malone, Lepper, ...

J.; Wichoski, U.; Wrede, G.; Yang, L.; Yen, Y. -R; Zeldovich, O. Ya.; Zettlemoyer, J.; Ziegler, T. (2018-02-15)
    Results from a search for neutrinoless double-beta decay (0νββ) of 136Xe are presented using the first year of data taken with the upgraded EXO-200 detector. Relative to previous searches by EXO-200, the energy resolution ...
  • The Impact of the Monographs Crisis on the FIeld of Communication 
    Yates, Steven D.; Chapman, Karen
    This study replicates and extends Yates and Chapman’s [(2007), Behavioral & Social Sciences Librarian, 26(1), 39-51] study of references from Communication Monographs, Communication Research, and Journal of Communication ...
  • Sector Analysis and the Study of Poetry: A Paradigmatic Explication of Syntactic Structures in John Donne's "Goodfriday, 1613. Riding Westward" 
    Katz, Elaine S. (University of Alabama Libraries, 1978)
    College instruction in poetry systematically treats, prosody, symbolism, imagery, lexicology, the history of ideas, and critical biography--by no means to exhaust the list. Common sense dictates that it should be possible ...
