Bayesian Optimization for Mixed-Variable Problems in the Natural Sciences
Yuhao Zhang, Ti John, Matthias Stosiek +1
Optimizing expensive black-box objectives over mixed search spaces is a common challenge across the natural sciences. Bayesian optimization (BO) offers sample-efficient strategies…
Role of photonic interference in exciton-mediated magneto-optic responses
Güven Budak, Christian Riedel, Akashdeep Kamra +4
Coupled optical and magnetic excitations can give rise to remarkably strong magneto-optic responses. This is particularly evident in van der Waals magnets, such as the antiferromag…
Local density of state fluctuations in 2D superconductor as a probe of quantum diffusion
Mathieu Lizée, Matthias Stosiek, Christophe Brun +2
The interplay of superconductivity and disorder generates a wealth of complex phenomena. In particular, the peculiar structure of diffusive electronic wavefunctions is predicted to…
Multifractal correlations of the local density of states in dirty superconducting films
M. Stosiek, F. Evers, I. S. Burmistrov
Mesoscopic fluctuations of the local density of states encode multifractal correlations in disorderedelectron systems. We study fluctuations of the local density of states in a sup…
Friedel Oscillations and superconducting-gap enhancement by impurity scattering
Matthias Stosiek, Clemens Baretzky, Timofey Balashov +2
Experiments observe an enhanced superconducting gap over impurities as compared to the clean-bulk value. In order to shed more light on this phenomenon, we perform simulations with…
Self-consistent-field ensembles of disordered Hamiltonians: Efficient solver and application to superconducting films
Matthias Stosiek, Bruno Lang, Ferdinand Evers
Our general interest is in self-consistent-field (scf) theories of disordered fermions. They generate physically relevant sub-ensembles ("scf-ensembles") within a given Altland-Zir…
