摘要：

The microscopic structure of a quantized vortex core in 2D He-4 is investigated using the fixed-phase approach. We present a general method to suggest new forms for the phase of a many-particle wave function. Starting from the Feynman phase, our scheme generates backflow corrections with qualitatively different properties than the starting Feynman vortex. We evaluate particle density, circulating current, core radius, and energy for an isolated vortex at zero temperature using Green's function Monte Carlo.
