Chronological Contrastive Learning: Few-Shot Progression Assessment in Irreversible Diseases

Clemens Watzenböck, Daniel Aletaha, Michaël Deman +9

Quantitative disease severity scoring in medical imaging is costly, time-consuming, and subject to inter-reader variability. At the same time, clinical archives contain far more lo…

Non-linear responses and three-particle correlators in correlated electron systems exemplified by the Anderson impurity model

Patrick Kappl, Friedrich Krien, Clemens Watzenböck +1

Three-particle correlators are relevant for, among others, Raman, Hall and non-linear responses. They are also required for the next order of approximations extending dynamical mea…

Long-term memory magnetic correlations in the Hubbard model: A dynamical mean-field theory analysis

Clemens Watzenböck, Martina Fellinger, Karsten Held +1

We investigate the onset of a not-decaying asymptotic behavior of temporal magnetic correlations in the Hubbard model in infinite dimensions. This long-term memory feature of dynam…

Photoexcitations in the Hubbard model -- generalized Loschmidt amplitude analysis of impact ionization in small clusters

Clemens Watzenböck, Markus Wallerberger, Laurenz Ruzicka +3

We study photoexcitations in small Hubbard clusters of up to 12 sites, some of which show an increase of the double occupation after the electric field pulse through impact ionizat…

Efficient Adaptive Computation of the Dynamics of Mott Transistors

Winfried Auzinger, Lukas Einramhof, Karsten Held +4

We investigate time-adaptive Magnus-type integrators for the numerical approximation of a Mott transistor. The rapidly attenuating electromagnetic field calls for adaptive choice o…

Efficient Magnus-type integrators for solar energy conversion in Hubbard models

Winfried Auzinger, Juliette Dubois, Karsten Held +7

Strongly interacting electrons in solids are generically described by Hubbardtype models, and the impact of solar light can be modeled by an additional time-dependence. This yields…
