libdlr: Efficient imaginary time calculations using the discrete Lehmann representation
Jason Kaye, Kun Chen, Hugo U. R. Strand
We introduce libdlr, a library implementing the recently introduced discrete Lehmann representation (DLR) of imaginary time Green's functions. The DLR basis consists of a collectio…

Discrete Lehmann representation of imaginary time Green's functions
Jason Kaye, Kun Chen, Olivier Parcollet
We present an efficient basis for imaginary time Green's functions based on a low rank decomposition of the spectral Lehmann representation. The basis functions are simply a set of…
