Optimization of path-integral tensor-multiplication schemes in open quantum systems
L. M. J. Hall, A. Gisdakis, E. A. Muljarov
Path-integral techniques are a powerful tool used in open quantum systems to provide an exact solution for the non-Markovian dynamics. However, the exponential scaling of the tenso…

Rigorous theory of coupled resonators
E. A. Muljarov
We demonstrate the general failure of the famous concept of tight binding and mode hybridization underlying modern theories of coupled open resonators. In spite of sophisticated ex…
