An O(N) symmetric extension of the Sine-Gordon Equation
Fred Cooper, Pasquale Sodano, Andrea Trombettoni +1
We discuss an O(N) exension of the Sine-Gordon (S-G)equation which allows us to perform an expansion around the leading order in large-N result using Path-Integral methods. In lead…
Nonsingular deformations of singular compactifications, the cosmological constant, and the hierarchy problem
Alan Chodos, Erich Poppitz, Dimitrios Tsimpis
We consider deformations of the singular "global cosmic string" compactifications, known to naturally generate exponentially large scales. The deformations are obtained by allowing…
Warp Factors and Extended Sources in Two Transverse Dimensions
Alan Chodos, Erich Poppitz
We study the solutions of the Einstein equations in (d+2)-dimensions, describing parallel p-branes (p=d-1) in a space with two transverse dimensions of positive gaussian curvature.…
The Gross-Neveu Model with Chemical Potential; An Effective Theory for Solitonic-Metallic Phase Transition in Polyacetylene?
Hisakazu Minakata, Alan Chodos
The Gross-Neveu model with chemical potential is investigated as a low-energy effective theory of polyacetylene. In particular, we focus on the abrupt change in the features of ele…
The TBA, the Gross-Neveu Model, and Polyacetylene
Alan Chodos, Hisakzau Minakata
We summarize recent work showing how the Thermodynamic Bethe Ansatz may be used to study the finite-density first-order phase transition in the Gross-Neveu model. The application t…
The Thermodynamic Bethe Ansatz and the 1/N Correction to the Density Phase Transition in the Gross-Neveu Model
Alan Chodos, Hisakazu Minakata
We compute the correction to the location of the previously found first-order phase transition in the Gross-Neveu model at a chemical potential $μ= μ_c = {1 \over \sqrt{2}} m…
Zeta function regularization in de Sitter space: the Minkowski limit
Alan Chodos, Andras Kaiser
We study an integral representation for the zeta function of the one-loop effective potential for a minimally coupled massive scalar field in D-dimensional de Sitter spacetime. By…
Symmetry Breaking in the Static Coordinate System of de Sitter Spacetime
András Kaiser, Alan Chodos
We study symmetry breaking in the static coordinate-system of de Sitter space. This is done with the help of the functional-Schrödinger approach used in previous calculations by Ra…
