Vortex lines in the three-dimensional XY model with random phase shifts.
The stability of the ordered phase of the three-dimensional XY model with random phase shifts is studied by considering the roughening of a single stretched vortex line due to disorder. It is shown that the vortex line may be described by a directed polymer Hamiltonian with an effective random potential that is long-range correlated. A Flory argument estimates the roughness exponent to z53/4 an...
متن کاملGeometry and scaling of tangled vortex lines in three-dimensional random wave fields
The shortand long-scale behaviour of tangled wave vortices (nodal lines) in random three-dimensional wave fields is studied via computer experiment. The zero lines are tracked in numerical simulations of periodic superpositions of threedimensional complex plane waves. The probability distribution of local geometric quantities such as curvature and torsion are compared to previous analytical and...
متن کاملRandom Vortex Method for Geometries with Unsolvable Schwarz-Christoffel Formula
In this research we have implemented the Random Vortex Method to calculate velocity fields of fluids inside open cavities in both turbulent and laminar flows. the Random Vortex Method is a CFD method (in both turbulent and laminar fields) which needs the Schwarz-Christoffel transformation formula to map the physical geometry into the upper half plane. In some complex geometries like the flow in...

متن کاملQuasi-long-range order in the 2D XY model with random phase shifts
We study the square-lattice XY model in the presence of random phase shifts. We consider two different disorder distributions with zero average shift and investigate the low-temperature quasi-long-range order phase which occurs for sufficiently low disorder. By means of Monte Carlo simulations we determine several universal quantities which are then compared with the analytic predictions of the...
