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: 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.

Topic: Cosmic rays at the highest energy
Description: The Pierre Auger Observatory [1] is the largest cosmic ray physics experiment in the world. It registers cosmic particles of energies far beyond the reach of any terrestrial accelerator over an area of 3000 sq. kms of Argentine pampa. The aim of the Observatory is to determine the energy spectrum and arrival directions of the particles and answer the question of their origin - whether they are produced in unknown cosmic accelerators or in decays of hypothetical dark matter particles. The Observatory is in fact indispensable to the whole field of ultra-high energy cosmic ray physics. As this scientific field rapidly evolves, the structure, size and complexity of the Observatory need to be modified to answer the newly appearing questions in sufficient detail. This is the major motivation for the ongoing upgrade of the Observatory called AugerPrime. While the particle flux suppression above the GZK energies was unambiguously established by the Observatory and some hints towards origin of cosmic ray sources were recently found, the questions of the cosmic ray composition at ultra-high energies, location of sources of these rare particles and the characteristics of their hadronic interactions remain open and will be addressed by the upgraded Observatory. New analysis techniques at the Observatory will be developed by the student as well as new emerging detection techniques of cosmic rays will be investigated such as within the simplified fluorescence telescopes FAST [2].

Topic: Physical properties of multifunctional thin films
Description: The research topic combines the fabrication of multifunctional metal, metal oxide and nitride thin films by physical vapor techniques (thermal evaporation, magnetron sputtering, reactive magnetron sputtering) and experimental testing of their structural and 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.
Supervisor: Mgr. Radim Čtvrtlík, Ph.D.
Topic: Synthesis of 1D structures and their decoration using plasma techniques
Description: The research topic covers mainly 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.
