Phase dispersion minimization

Phase separation in the Allen-Cahn equation, with a start in slow motion

Like the video https://youtu.be/t1swj0QJUTw this simulation shows a solution of the Allen-Cahn equation for phase separation, on a rectangular domain with periodic boundary conditions, starting from a random initial configuration. Time has been slowed down at the beginning, to give a bette

Phase separation in the Allen-Cahn equation

This video is a high resolution remake of some old simulations on this channel, such as https://youtu.be/NtEhToQOiys . It shows a solution of the Allen-Cahn equation for phase separation, on a rectangular domain with periodic boundary conditions. Phase separation occurs in mixtures of two

Convolution in the time domain

Now that you understand the Fourier transform, it's time to start learning about time-frequency analyses. Convolution is one of the best ways to extract time-frequency dynamics from a time series. Convolution can be conceptualized and implemented in the time domain or in the frequency doma
