Analysis of single-excitation states in quantum optics
Jeremy Hoskins, Jason Kaye, Manas Rachh +1
In this paper we analyze the dynamics of single-excitation states, which model the scattering of a single photon from multiple two level atoms. For short times and weak atom-field…
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…
A fast time domain solver for the equilibrium Dyson equation
Jason Kaye, Hugo U. R. Strand
We consider the numerical solution of the real time equilibrium Dyson equation, which is used in calculations of the dynamical properties of quantum many-body systems. We show that…
A fast, high-order numerical method for the simulation of single-excitation states in quantum optics
Jeremy Hoskins, Jason Kaye, Manas Rachh +1
We consider the numerical solution of a nonlocal partial differential equation which models the process of collective spontaneous emission in a two-level atomic system containing a…
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…
