• Skyrmion Solutions to the Weinberg-Salam Model 

  Eilam, G.; Klabucar, D.; Stern, Allen (1986-03-31)

  We find a spherically symmetric solution to the gauged SU(2)L ⊗ SU(2)R chiral model. It corresponds to a new classical solution to the Weinberg-Salam model in the limit of infinite self-coupling and sin^2θW = 0. It has an ...
• 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 ...
