Fast iterative solution of the Bethe–Salpeter eigenvalue problem using low-rank and QTT tensor approximation
In this paper, we propose and study two approaches to approximate the solution of the Bethe–Salpeter equation (BSE) by using structured iterative eigenvalue solvers. Both approaches are based on the reduced basis method and...
