Influence of Markovianity and self-consistency on time-resolved spectral functions of driven quantum systems
Thomas Blommel, M. Rey Lambert, Michael A. Kurniawan +2
We present a systematic comparison of the real-time Dyson expansion (RTDE) with established non-equilibrium Green's function approaches for simulating driven, interacting quantum s…

A Practical Framework for Simulating Time-Resolved Spectroscopy Based on a Real-time Dyson Expansion
Cian Reeves, Michael Kurniawan, Yuanran Zhu +5
Time-resolved spectroscopy is a powerful tool for probing electron dynamics in molecules and solids, revealing transient phenomena on sub-femtosecond timescales. The interpretation…

The role of effective mass and long-range interactions in the band-gap renormalization of photo-excited semiconductors
Cian C. Reeves, Scott K. Cushing, Vojtech Vlcek
Understanding how to control changes in electronic structure and related dynamical renormalizations by external driving fields is the key for understanding ultrafast spectroscopy a…
