A cubic scaling algorithm for excited states calculations in particle-particle random phase approximation
Jianfeng Lu, Haizhao Yang
The particle-particle random phase approximation (pp-RPA) has been shown to be capable of describing double, Rydberg, and charge transfer excitations, for which the conventional ti…
Recursive Diffeomorphism-Based Regression for Shape Functions
Jieren Xu, Haizhao Yang, Ingrid Daubechies
This paper proposes a recursive diffeomorphism based regression method for one-dimensional generalized mode decomposition problem that aims at extracting generalized modes $α_k(t)s…
Interpolative Butterfly Factorization
Yingzhou Li, Haizhao Yang
This paper introduces the interpolative butterfly factorization for nearly optimal implementation of several transforms in harmonic analysis, when their explicit formulas satisfy c…
Preconditioning orbital minimization method for planewave discretization
Jianfeng Lu, Haizhao Yang
We present an efficient preconditioner for the orbital minimization method when the Hamiltonian is discretized using planewaves (i.e., pseudospectral method). This novel preconditi…
