Real-time Dyson expansion for the nonequilibrium approximation: Correlated spectra and dependence on the reference propagator
Erik Schroedter, Jan-Philip Joost, Michael Bonitz +1
Electronic spectra provide direct insight into the excitations and correlations of condensed matter systems. Their description requires electron correlations beyond mean field. In…
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…
Predicting nonequilibrium Green's function dynamics and photoemission spectra via nonlinear integral operator learning
Yuanran Zhu, Jia Yin, Cian C. Reeves +2
Understanding the dynamics of nonequilibrium quantum many-body systems is an important research topic in a wide range of fields across condensed matter physics, quantum optics, and…
Performance of wave function and Green's functions based methods for non equilibrium many-body dynamics
Cian C. Reeves, Gaurav Harsha, Avijit Shee +5
Theoretical descriptions of non equilibrium dynamics of quantum many-body systems essentially employ either (i) explicit treatments, relying on truncation of the expansion of the m…
A Real-time Dyson Expansion Scheme: Efficient Inclusion of Dynamical Correlations in Non-equilibrium Spectral Properties
Cian Reeves, Vojtech Vlcek
Time-resolved photoemission spectroscopy is the key technique to probe the real-time non-equilibrium dynamics of electronic states. Theoretical predictions of the time dependent sp…
Exploiting Maximally Mixed States for Spectral Estimation by Time Evolution
Kaelyn J. Ferris, Zihang Wang, Itay Hen +3
We introduce a novel approach for estimating the spectrum of quantum many-body Hamiltonians, and more generally, of Hermitian operators, using quantum time evolution. In our approa…
Learning nonlinear integral operators via Recurrent Neural Networks and its application in solving Integro-Differential Equations
Hardeep Bassi, Yuanran Zhu, Senwei Liang +4
In this paper, we propose using LSTM-RNNs (Long Short-Term Memory-Recurrent Neural Networks) to learn and represent nonlinear integral operators that appear in nonlinear integro-di…
