Modelling quantum measurement dynamics: from decoherence to redundancy with site-hopping indistinguishable particles
Katja Schneeweiss, Tom Rivlin, Maximilian P. E. Lock +2
In recent years, new theoretical insights into decoherence and quantum measurements have emerged through the study of many-body dynamics in isolated quantum systems. It is now unde…
Capturing reduced-order quantum many-body dynamics out of equilibrium via neural ordinary differential equations
Patrick Egenlauf, Iva Březinová, Sabine Andergassen +1
Out-of-equilibrium quantum many-body systems exhibit rapid correlation buildup that underlies many emerging phenomena. Exact wave-function methods to describe this scale exponentia…
Projective purification of correlated reduced density matrices
Elias Pescoller, Marie Eder, Iva Březinová
In the search for accurate approximate solutions of the many-body Schrödinger equation, reduced density matrices play an important role, as they allow to formulate approximate meth…
Dynamical quasi-condensation in the weakly interacting Fermi-Hubbard model
Iva Březinová, Markus Stimpfle, Stefan Donsa +1
We study dynamical (quasi)-condensation in the Fermi-Hubbard model starting from a completely uncorrelated initial state of adjacent doubly occupied sites. We show that upon expans…
Non-equilibrium correlation dynamics in the one-dimensional Fermi-Hubbard model: A testbed for the two-particle reduced density matrix theory
Stefan Donsa, Fabian Lackner, Joachim Burgdörfer +4
We explore the non-equilibrium dynamics of a one-dimensional Fermi-Hubbard system as a sensitive testbed for the capabilities of the time-dependent two-particle reduced density mat…
The dynamically screened ladder approximation: Simultaneous treatment of strong electronic correlations and dynamical screening out of equilibrium
Jan-Philip Joost, Niclas Schlünzen, Hannes Ohldag +3
Dynamical screening is a key property of charged many-particle systems. Its theoretical description is based on the approximation that is extensively applied for ground-state…
