A study of the chiral phase transition in the nonlinear sigma model
… studied using the three dimensional non-linear sigma model. Numerical simulations with the U(N) $\times$ U(N) and SU(N) $\times$ SU(N) flavor symmetries for both two and three flavors were examined to determine the order of the phase transition. The data from the simulations in the appropriate …

… is studied using the three dimensional nonlinear sigma model. Numerical simulations with the U(N) x U(N) and SU(N) x SU(N) flavor symmetries for both two and three flavors were examined to determine the order of the phase transition. The data from the simulations in the appropriate …

Études on fuzzy geometry and cosmology
… study the BPS and non-BPS solutions of the CJPN nonlinear sigma model on the noncommutative plane in some detail and show among other things that a class of its solitonic excitations may be built from bound states of noncommutative scalar solitons. We then go on to construct a fuzzy extension of …

Some Aspects of Fluctuation Driven Phenomena
… near-equilibrium critical dynamics of the O(3) nonlinear sigma model describing isotropic antiferromagnets with a non-conserved order parameter reversibly coupled to the conserved total magnetization. We find that in equilibrium, the dynamics is well-separated from the statics and the static …

Chiral Rings of Two-dimensional Field Theories with (0,2) Supersymmetry
… operators in general two-dimensional (0,2) nonlinear sigma models, both in theories twistable to the A/2 or B/2 model, as well as in non-twistable theories. As a special case, we study the quantum sheaf cohomology of Grassmannians as a deformation of the usual quantum cohomology. The …

Coupled one dimensional electron systems and stripe phases of high temperature superconductors
… chapter, I study an extended Hubbard-Heisenberg model on two types of two leg ladders, a model without flux and a model with flux $\pi$ per plaquette. In the case of the conventional (flux-less) ladder the Pair density wave state arises for certain filling fractions when commensurability …
