Topic: Study of processes of diffractive production at the LHC.
Description: Diffractive processes in proton-proton or proton-nucleus collisions, as observed or expected to be seen at the LHC, represent a unique kinematic domain of interactions. Particles in the initial state can survive the interaction without altering their additive quantum numbers, while the inelastically transferred energy in the collision gives rise to a system of secondary particles, similar to what occurs in non-diffractive interactions. The kinematics of the final state in diffraction processes include original particles scattered at small angles, retaining a significant fraction of their initial momentum. This signature allows for the experimental identification and separation of diffraction processes. The ATLAS experiment at the LHC has collected and will continue to collect data enabling the study of diffraction processes. An important aspect of LHC data analysis is the examination of simulated data produced using collision event generators based on the Monte Carlo method. These generators perform the integration of theoretical cross-sections and random generation of collision events. Work on the development of generators for diffraction processes has been relatively limited in recent years, presenting an opportunity to make significant contributions and stimulate progress in this field.

Topic: Collective measurements for quantum communications
Description: Collective measurements are quantum measurements carried out simultaneously on multiple copies of the quantum state under investigation. They have been shown to be an invaluable tool for efficiently detecting and quantifying several key properties of quantum states, such as different entanglement measures or stronger quantum correlations. At the same time, collective measurements can be easily implemented in quantum communications networks, making them a key tool for the operation of prospective large-scale quantum networks connecting multiple users. Thus, the study of collective measurements promises interesting fundamental insights as well as results applicable to practical quantum communications.

Topic: Fisher information in classical and quantum optics
Description: Fisher information is a quantity that allows the calculation of the uncertainty with which the value of a parameter can be determined. In classical and quantum optics, it is used to calculate the uncertainty with which the value of the phase in a Mach-Zehnder interferometer can be determined. Calculations of measurement uncertainty for different types of light will be performed. The results obtained using classical and quantum methods will be compared with each other.

Topic: Characteristics of Low-Photon Detectors for Next-Generation Neutrino Experiments
Description: The Water Cherenkov Test Experiment (WCTE) is an ongoing experiment on a secondary particle beam at CERN. Its purpose is to test technologies for the upcoming neutrino experiment Hyper-Kamiokande (Hyper-K) and measure certain particle cross-sections, such as those of muons and pions, as they pass through matter. The test beam campaigns focused both on monitoring the composition of the beam using aerogel Cherenkov detectors and time-of-flight scintillation detectors—with the use of photomultipliers, digital readout, and subsequent data processing—and on testing multi-PMT modules for the IWCD (Intermediate Water Cherenkov Detector) and the Hyper-K experiment itself. The latter is scheduled for assembly in 2028 and will begin collecting calibration and physics data. For its physics program, simulations and feasibility studies will be crucial, along with work on reconstructing the kinematics of particles producing Cherenkov signals and separating the signal from background. The student will contribute to testing photomultipliers for the IWCD and Hyper-K detectors in the Joint Laboratory of Optics and will also have the opportunity to actively participate in the analysis of existing data of 2025 from the WCTE experiment. They will become familiar with tools for data analysis in high-energy physics using a small-scale version of the detector for future neutrino observatories and will engage in construction, simulations, and possibly analysis of available data from the Hyper-K experiment.

The student will have the opportunity to contribute to simulations of the WCTE and Hyper-Kamiokande experiments using the WCSim program based on the Geant4 toolkit. Additionally, he/she will use available reconstruction tools, such as likelihood-based methods (fitQun) or machine learning approaches (WatChMaL), to analyze data from 2025 from the WCTE experiment. The student will gain experience with data analysis tools in high-energy physics using a small-scale version of the detector for future neutrino observatories and will also engage in construction, simulations, and potentially analysis of available data from the Hyper-K experiment.

Topic: Noclassical properties of simple PT-symmetric quantum systems described using methods of quantum statistical physics
Description: Simple quantum PT-symmetric and generalized systems like two- and more-level atoms and multi-mode optical bosonic systems will be studied from the point of view of their nonclassical properties. The analyzed systems will be described by Liouvillians and attention will be paid to their asymptotic behavior. Exceptional points are the striking features of PT-symmetric systems. At these points, the system behavior qualitatively changes, which may be used, e.g., for increasing sensitivity of quantum measurements. We will identify the exceptional points of analyzed systems including their degeneracies and study the behavior of system nonclassicality close to these points. We will look for suitable applications that expoint the striking properties of the analyzed systems.
