چکیده
1. Abstract We study the stochastic quantization of two-dimensional nonlinear sigma model in the large N limit. Our main tool is the effective Langevin equation with which we investigate nonperturbative phenomena and derive the results which are same as the path integral approach gives.

Role of long jumps in surface diffusion.
We analyze a probability of atomic jumps for more than one lattice spacing in activated surface diffusion. First, we studied a role of coupling between the x and y degrees of freedom for the diffusion in a two-dimensional substrate potential. Simulation results show that in the underdamped limit the average jump length scales with the damping coefficient eta as proportional, v...
متن کاملScaling of ballistic deposition from a Langevin equation.
An exact lattice Langevin equation is derived for the ballistic deposition model of surface growth. The continuum limit of this equation is dominated by the Kardar-Parisi-Zhang (KPZ) equation at all length and time scales. For a one-dimensional substrate the solution of the exact lattice Langevin equation yields the KPZ scaling exponents without any extrapolation. For a two-dimensional substrat...
متن کاملDynamical Symmetry Breaking on Langevin Equation : Nambu · Jona - Lasinio Model
In order to investigate dynamical symmetry breaking, we study Nambu·JonaLasinio model in the large-N limit in the stochastic quantization method. Here in order to solve Langevin equation, we impose specified initial conditions and construct “effective Langevin equation” in the large-N limit and give the same non-perturbative results as path-integral approach gives. Moreover we discuss stability...
متن کاملMassive Nonlinear Sigma Models and BPS Domain Walls in Harmonic Superspace
Four-dimensional massive N = 2 nonlinear sigma models and BPS wall solutions are studied in the off-shell harmonic superspace approach in which N = 2 supersymmetry is manifest. The general nonlinear sigma model can be described by an analytic harmonic potential which is the hyper-Kähler analog of the Kähler potential in N = 1 theory. We examine the massive nonlinear sigma model with multi-cente...
متن کاملTwo-dimensional Heisenberg model with nonlinear interactions.
We investigate a two-dimensional classical N-vector model with a nonlinear interaction (1+sigma(i) x sigma(j))(p) in the large-N limit. As observed for N=3 by Blöte et al. [Phys. Rev. Lett. 88, 047203 (2002)], we find a first-order transition for p>p(c) and no finite-temperature phase transitions for pp(c), both phases have short-range order, the correlation length showing a finite...
