Zero modes of the vortex-fermion system
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),…
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 three…
Large-n critical behavior of O(n)×O(m) spin models
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…
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),…
Gromov-Witten theory of orbicurves, the space of tri-polynomials and symplectic field theory of Seifert fibrations
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…
The large-N expansion of unitary-matrix models
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-theoretic…
Double Ramification Cycles and Quantum Integrable Systems
In this paper, we define a quantization of the Double Ramification Hierarchies of Buryak (Commun Math Phys 336:1085–1107, 2015) and Buryak and Rossi (Commun Math Phys, 2014), using intersection…
