Quantum transport enabled by non-adiabatic transitions
Ajith Ramachandran, Alexander Eisfeld, Sebastian Wüster +1
Quantum transport of charge or energy in networks with discrete sites is central to diverse quantum technologies, from molecular electronics to light harvesting and quantum opto-me…
Topological edge states in a Rydberg composite
Matthew T. Eiles, Christopher W. Wächtler, Alexander Eisfeld +1
We examine topological phases and symmetry-protected electronic edge states in the context of a Rydberg composite: a Rydberg atom interfaced with a structured arrangement of ground…
Simulating optical linear absorption for mesoscale molecular aggregates: an adaptive hierarchy of pure states approach
Tarun Gera, Lipeng Chen, Alex Eisfeld +3
In this paper, we present a new method for calculating linear absorption spectra for large molecular aggregates, called dyadic adaptive HOPS (DadHOPS). This method combines the ada…
Calculating non-linear response functions for multi-dimensional electronic spectroscopy using dyadic non-Markovian quantum state diffusion
Lipeng Chen, Doran I. G. Bennett, Alexander Eisfeld
We present a methodology for simulating multi-dimensional electronic spectra of molecular aggregates with coupling of electronic excitation to a structured environment using the st…
Recompilation-enhanced simulation of electron-phonon dynamics on IBM Quantum computers
Ben Jaderberg, Alexander Eisfeld, Dieter Jaksch +1
Simulating quantum systems is believed to be one of the first applications for which quantum computers may demonstrate a useful advantage. For many problems in physics, we are inte…
Gaussian Process Regression for Absorption Spectra Analysis of Molecular Dimers
Farhad Taher-Ghahramani, Fulu Zheng, Alexander Eisfeld
A common task is the determination of system parameters from spectroscopy, where one compares the experimental spectrum with calculated spectra, that depend on the desired paramete…
