Quantization of charged fields in the presence of intense electromagnetic fields
This thesis applies techniques from quantum field theory in curved spacetimes to study particle creation in external fields, focusing on the Schwinger effect (i.e., the production of particle-antiparticle pairs by intense electric fields). Although experimental verification remains out of reach, theoretical analysis advances our understanding of this phenomenon and its broader implications. The work develops the theoretical framework for quantizing charged fields in nontrivial backgrounds, ad…

Superconducting spin valve effect in Fe/Si$_3$N$_4$/Pb/Si$_3$N$_4$/Fe heterostructures
The structures of the superconducting spin valve (SSV) Fe/\allowbreak Si$_3$N$_4$/\allowbreak Pb/\allowbreak Si$_3$N$_4$/\allowbreak Fe (where Si$_3$N$_4$ is a dielectric insulating layer of controlled thickness) were investigated. The dependence of the magnitude of the SSV effect on the thicknesses of the superconducting (S) and insulating (I) layers was studied. Optimization of the S and I layer thicknesses enabled a complete switching between the normal and superconducting states when the mu…

Phenomenal day at the Victoria & Albert. It's as great as the British Museum but instead of singular historical works it's full of collections of terrific manufactured things. Lots of photos! Here starting with four sculptures.

IPbus extension for the ALFRED framework
We present a development of the ALFRED framework that includes support for the IPbus protocol, created for the Fast Interaction Trigger (FIT) detector in the ALICE experiment at CERN. This modification resolves the incompatibility between the current GBT-based slow-control protocols and the FIT electronics, which is based on the IPbus. A compatibility layer, named ALF IPbus, was created in C++ and integrated with DIM services, allowing for the transparent conversion of SWT frames into IPbus tra…
