We study the problem of predicting highly localized low-lying eigenfunctionsin bounded domainsfor rapidly varying potentialsV. Filoche and Mayboroda introduced the function 1/u, where, as a suitable regularization ofVfrom whose minima one can predict the location of eigenfunctions with high accuracy. We proposed a fast method that produces a landscapes that is exceedingly similar, can be used for the same purposes and can be computed very efficiently: the computation time on angrid, for example, is merely, the cost of two FFTs
