Numerical Study of Wheeler-Dewitt Equation beyond Slow-roll approximation
Jie Jiang, Deog Ki Hong, Dong-han Yeom
The Wheeler-DeWitt (WDW) equation is analyzed using two boundary proposals: the Hartle-Hawking no-boundary condition and tunneling condition. By compactifying the scale factor …

Numerical Investigation of Two-Dimensional Fokker-Planck Equation in Inflationary Models: Importance of Slow-Roll Parameters
Deog Ki Hong, Jie Jiang, Dong-han Yeom
In this study, we generalize the Fokker-Planck equation to two-dimensional cases, including potential functions with periodic boundary conditions and piecewise-defined structures,…
