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
- M. Campostrini, M. Hasenbusch, A. Pelissetto, P. Rossi, E. Vicari
- Physics
- 24 October 2000
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 shown… Expand
25th-order high-temperature expansion results for three-dimensional Ising-like systems on the simple-cubic lattice.

- 11 January 2002
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 three… Expand
Large-n critical behavior of O(n)×O(m) spin models
- A. Pelissetto, P. Rossi, E. Vicari
- Physics
- 3 April 2001
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. We… Expand
Gromov-Witten theory of orbicurves, the space of tri-polynomials and symplectic field theory of Seifert fibrations
- P. Rossi
- Mathematics, Physics
- 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. A… Expand
Critical exponents and equation of state of the three-dimensional Heisenberg universality class
- M. Campostrini, M. Hasenbusch, A. Pelissetto, P. Rossi, E. Vicari
- Physics
- 17 October 2001
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
Integrable systems and holomorphic curves
- P. Rossi
- Mathematics, Physics
- 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 first… Expand
Critical behavior of frustrated spin models with noncollinear order
- A. Pelissetto, P. Rossi, E. Vicari
- Physics
- 25 July 2000
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-theoretic… Expand
On the exact evaluation of 〈det Up〉 in a lattice gauge model
- P. Rossi
- Physics
- 4 November 1982
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 of… Expand
