Doctoral program Applied Physics

Program description

The PhD study program Applied Physics is scientifically orientated. It aims at material physics, applied quantum and nonlinear optics, particle physics and astrophysics, nuclear spectroscopic methods, optical technologies and modelling and simulations. Material physics mainly involves physical methods of material preparation and analysis of physical properties of materials. Optical and mechanical properties of materials, surfaces of layered structures and their interfaces are studied. In the area of quantum and nonlinear optics, methods of generation and detection of non-classical states of light, applications of quantum correlations and entanglement in metrology, imaging and quantum information processing are addressed. Special attention is devoted to the process of parametric down-conversion and investigations of properties of weak and strong optical fields composed of photon pairs. In the area of particle physics and astrophysics, the PhD study aims at production and analysis of properties of heavy particles, especially top quark, in ATLAS experiment at CERN labs. Attention is devoted to the physics of elastic and diffraction protons with sub-detectors ALFA and AFP, at whose operation, simulation as well as development the involved departments participate. In the area of astrophysics, the PhD program consists of the study of cosmic radiation and building of experimental components and devices for astrophysical observatories in the framework of international collaborations. Data acquired by these detectors are analysed. Topics related to international collaborations Pierre Auger Observatory and Cherenkov Telescope Array are solved in cooperation with Institute of Physics of the Czech Academy of Sciences. In the area of nuclear spectroscopic methods, the Mossbauer spectroscopy is mainly studied with emphasis to detection of gamma radiation. Moreover, also special methods like spectroscopy of converted electrons of nuclear forward scattering of synchrotron radiation are studied. Also in-situ investigations of material properties using selected nuclear spectroscopic methods are discussed. New measurement devices and software for data analysis are developed. Creation and stability of super-heavy elements including development of suitable detectors is studied in cooperation with United Institute for Nuclear Research (JINR) in Dubna (Russia). In the area of optical technologies, various optical methods for contactless 3D topography, involving optical topography methods, interferometric methods and methods based on optical speckle, are developed. Attention is paid to modelling and simulations of physical processes in the above discussed area of physics. Among others, quantum processes in nonlinear media including modern photonic sources are modelled.

Topic: Complete characterization of strip silicon detectors developed for the ATLAS Inner Tracker by using testbeams and computer simulations
Description: The Large Hadron Collider accelerator at CERN will be upgraded to the High-Luminosity Large Hadron Collider (HL-LHC) machine between 2024 and 2027. The instantaneous luminosity of the HL-LHC will reach 7×1034 cm-2s-1, corresponding to an average of 200 inelastic proton-proton collisions per bunch crossing, and the total integrated luminosity delivered to the ATLAS experiment will be higher than 4000 fb-1. Parameters of the HL-LHC accelerator thus imply high requirements on radiation hardness, granularity, as well as the speed of data transfer and data processing of the inner tracking detector. The current inner detector of the ATLAS experiment will be replaced by the completely new all-silicon Inner Tracker (ITk), which will consist of pixel and strip silicon detectors. The main topic of this doctoral thesis is a detailed characterization of detection properties of strip silicon detectors developed by the ATLAS ITk collaboration. This characterization will be performed by using testbeams of ultrarelativistic electrons and hadrons at DESY II and CERN SPS synchrotrons using the EUDET beam Telescope built from several pixel silicon detectors located in front of and behind of the tested sample. The recorded experimental data will be compared to outputs of computer simulations prepared in Allpix Squared and Athena simulation frameworks which provide libraries to simulate a complete testbeam experiment, starting from the calculation of energy deposited by a charged particle passing through the silicon sensor to the signal digitization in individual readout channels.

Topic: Synthesis of 1D structures and their decoration using plasma techniques
Description: Synthesis of arrays of 1D nanostructured semiconducting materials is an important topic in materials research due to their very high surface to volume ratio, robust chemical and environmental stability and less charge carrier recombination. Nanostructured 1D materials can be further functionalized with the decoration of another semiconducting or metal nanostructure by plasma-based technique or by chemical-based technique. Those functionalized nanostructures can be highly advantageous for various applications including sensors, battery or supercapacitors, etc. In the proposed research work, we want to study the formation of 1D nanostructured materials of metal oxides by chemical as well as plasma-based techniques. These functional 1D nanomaterials will be grown by hydrothermal as well as by electrochemical anodization-based processes. For enhancing the crystallinity of those 1D materials thermal annealing will be carried out. Furthermore, the functional properties of these 1D nanomaterials will be further tuned by decorating another functional material by means of either magnetron sputtering or chemical or electrochemical based processes. In particular, the effort will be devoted to the relationship between physical and chemical properties of created structures and conditions of technological processes as well as their applicability in various fields.

Topic: Physical properties of multifunctional thin films
Description: Metal and metal oxide semiconductor thin film fabrication gaining tremendous research interest due to its applicability in optoelectronic devices as a charge carrier transport layer, various types of sensors as well as a transparent conducting oxide. The chemical, optical and optoelectronic properties of the metal oxide thin films depend on several parameters for example thickness, crystallinity, different types of defects as well as the surface morphology of the thin films. The research topic combines the fabrication of multifunctional metal and metal oxide thin film fabrication by physical vapor techniques (thermal evaporation, magnetron sputtering, reactive magnetron sputtering) and experimental testing of structural, compositional characteristics. The functional properties of those films will be further tuned by means of plasma treatment and the thermal annealing process. The optical, electrical and optoelectronic properties of those thin films will be characterized using various sophisticated analytic technologies. Furthermore, the applicability of those thin films will be studied as a flexible chemo-sensor or photodetector.

Topic: Analysis of cosmic gamma ray events in the CTA experiment
Description: The Cherenkov Telescope Array Observatory (CTAO or CTA) is going to be the largest and technically most advanced ground-based facility for detection of high-energy cosmic gamma rays. CTA will be located at both the southern and norther hemisphere. Both locations will be equipped with three types of telescopes covering three ranges of energies of the incoming gamma photons. The ultimate sensitivity will span energies from 20 GeV to 100 TeV. The detection principle is based on detection of Cherenkov light in the telescopes generated by charged particles traversing a medium with a speed greater than the actual speed of light in the given medium, i.e. in atmosphere. The charged particles are created in cascades of interactions whose onset is the primary interaction of the incoming gamma photon with atoms in the atmosphere. The envisaged work is supposed to cover the tasks of analysis and interpretation of the measured data. The primary task of CTA is to measure the energy spectrum and distribution sources of the gamma photons.

The aim of this work will be focused on the analysis of data from the current FAST prototypes, optical simulations, and future giant array optimization.
