Zero modes of the vortex-fermion system
Abstract Electric charge of a fermion that is coupled only to the gauge field of an abelian vortex need not be quantized, in contrast the situation for a magnetic monopole field. Correspondingly,Expand

Critical behavior of the three-dimensional XY universality class
We improve the theoretical estimates of the critical exponents for the three-dimensional XY universality class. We find alpha=-0.0146(8), gamma=1.3177(5), nu=0.67155(27), eta=0.0380(4),Expand

Multimonopole solutions in the Prasad-Sommerfield limit
A variational search for multimonopole solutions of the Yang-Mills-Higgs equations in the Prasad-Sommerfield limit is performed. An ansatz where two monopoles are superimposed at the origin is shownExpand

25th-order high-temperature expansion results for three-dimensional Ising-like systems on the simple-cubic lattice.
25th-order high-temperature series are computed for a general nearest-neighbor three-dimensional Ising model with arbitrary potential on the simple cubic lattice. In particular, we consider threeExpand

Large-n critical behavior of O(n)×O(m) spin models
We consider the Landau-Ginzburg-Wilson Hamiltonian with O(n)x O(m) symmetry and compute the critical exponents at all fixed points to O(n^{-2}) and to O(\epsilon^3) in a \epsilon=4-d expansion. WeExpand

  • 19 August 2008
We compute, with symplectic field theory (SFT) techniques, the Gromov-Witten theory of $${\mathbb{P}^1_{\alpha_1,\ldots,\alpha_a}}$$, i.e., the complex projective line with a orbifold points. AExpand

Critical exponents and equation of state of the three-dimensional Heisenberg universality class
We improve the theoretical estimates of the critical exponents for the three-dimensional Heisenberg universality class. We find gamma=1.3960(9), nu=0.7112(5), eta=0.0375(5), alpha=-0.1336(15),Expand

  • 2 December 2009
In this paper we attempt a self-contained approach to infinite dimensional Hamiltonian systems appearing from holomorphic curve counting in Gromov-Witten theory. It consists of two parts. The firstExpand

Critical behavior of frustrated spin models with noncollinear order
We study the critical behavior of frustrated spin models with noncollinear order, including stacked triangular antiferromagnets and helimagnets. For this purpose we compute the field-theoreticExpand

On the exact evaluation of 〈det Up〉 in a lattice gauge model
Abstract A simple analytic proof of Green and Samuel's conjecture on the behaviour of 〈det Up〉 in lattice QCD2 is found by exploiting the formal analogy of the model with the representation ofExpand
