Numerically exact simulation of open quantum networks with strong system-bath couplings using tensor network path integrals
Quentin W. Richter, Moritz Cygorek
Non-Markovian open quantum networks are among the most challenging problems in quantum theory, as they suffer from both, the exponentially scaling many-body state space as well as…

Atomistic Approach to Exciton-Phonon Couplings in Semiconductor Quantum Dots
Yasser Saleem, Moritz Cygorek
We present a fully atomistic approach to exciton-phonon coupling in semiconductor quantum dots that bridges microscopic electronic-structure calculations with non-Markovian open-qu…

Engineering Biquadratic Interactions in Spin-1 Chains by Spin-1/2 Spacers
Yasser Saleem, Weronika Pasek, Marek Korkusinski +2
Low-dimensional quantum systems host a variety of exotic states, such as symmetry-protected topological ground states in spin-1 Haldane chains. Real-world realizations of such stat…
