Stabilizing Inputs to Approximated Nonlinear Functions for Inference with Homomorphic Encryption in Deep Neural Networks
Moustafa AboulAtta, Matthias Ossadnik, Seyed-Ahmad Ahmadi
Leveled Homomorphic Encryption (LHE) offers a potential solution that could allow sectors with sensitive data to utilize the cloud and securely deploy their models for remote infer…
A Wave Packet Approach to Interacting Fermions
Matthias Ossadnik
In this thesis, we study the breakdown of the Fermi liquid state in cuprate superconductors using the renormalization group (RG). We seek to extend earlier work on the crossover fr…
Limiting mechanism for critical current in topologically frustrated Josephson junctions
Sarah B. Etter, Hirono Kaneyasu, Matthias Ossadnik +1
Eutectic SrRuO-Ru samples with m-sized Ru-metal inclusions support inhomogeneous superconductivity above the bulk transition of SrRuO in the so-called 3-Kelvin p…
Phase space analysis of interacting fermions
M. Ossadnik
We propose the use of an orthogonal wave packet basis to analyze the low-energy physics of interacting electron systems with short range order. We give an introduction to wave pack…
Numerical Study of Charge Transport of Overdoped LaSrCuO within Semiclassical Boltzmann Transport Theory
Jonathan M. Buhmann, Matthias Ossadnik, T. M. Rice +1
The in-plane resistivity of the high-temperature oxide superconductor LaSrCuO [LSCO] shows a strong growth of a contribution linear in temperature as the doping…
Functional renormalization group with counterterms for competing order parameters
M. Ossadnik, C. Honerkamp
We explore the possibilities of using the fermionic functional renormalization group to compute the phase diagram of systems with competing instabilities. In order to overcome the…
