Cas·i·mir effect

The effect of a net attractive force between objects in a vacuum, caused by the reduction of vacuum pressure in the space between the objects, where the wavelengths of vacuum fluctuations are more limited than in the space around the objects.

[After Hendrik Casimir (1909-2000), Dutch physicist who predicted its existence in collaboration with Dirk Polder (1919-2001), Dutch physicist.]

The advantage of using the self-normalizing matrix is that it allows the use of an iterative eigenvalue solver for the Casimir energy. In addition, this self-normalization greatly improves the numerical accuracy of the Casimir problem by removing numerical error due to cancellation.
Using the implementation of the A-EPA with point sampling [11,21], good results were achieved for both the Casimir energy and force.
