I am a mathematical physicist. My research interests include general relativity, gravitational optics, relativistic cosmological models and semiclassical physics.
This website is mainly dedicated to a project which is called WAQOU -- "Wavization and quantization of the observables in the Universe". I acted as a PI of this POLONEZ BIS fellowship in between Nov. 2022 and Nov. 2024. This research was part of the project No. 2021/43/P/ST2/01802 co-funded by the National Science Centre and the European Union Framework Programme for Research and Innovation Horizon 2020 under the Marie Skłodowska-Curie grant agreement no. 94533.
On the Polonez Bis Project
The observational information we obtain from the sky regarding the brightnesses, the distances and the image distortions of the astrophysical objects resides in the properties of a thin light bundle. It is true that we can treat light as a collection of particles, called photons, for many of the observations on the sky. This means that the ray picture of light is a good–enough approximation to detect certain phenomena in the Universe which belong to the subject field of Einstein’s theory of general relativity. On the other hand, it is also true that light demonstrates certain wave properties as well. In general, those wave properties can be classical or quantum in nature. However, there exists no generic formalism in the literature which studies the classical and quantum behavior of light in general relativistic scenarios.
In this project, we aim to fill this gap. Previously, we obtained the light bundle propagation in the Universe via a method that is analogous to the one of the light propagation through an optical device in Newtonian physics. This formalism has certain features that allow one to switch from the ray–picture to a wave–picture. In the current project, we would like to use this method in order to establish a theoretical framework to study (i) classical wave effects and (ii) quantum effects on the propagation of a thin light bundle which are most relevant for the observations on the sky. Even though the main objective is the light propagation, gravitational waves will be our other point of interest.
Within this project, we will try to find answers to some very important fundamentals problems. For example, how do the distance calculations of astrophysical objects change when we use wave–properties of light? Can one discover new wave phenomena in the Universe which are analogous to the ones we measure in a typical transistor of an electric kettle? More importantly how do the two distinct domains of physics (i.e., quantum and gravitational) can be merged considering the observations on the sky? Finding answers to those questions not only will help us to identify the ingredients of the Universe in a practical sense but it will also help us to understand our physical existence in the Universe on a foundational level.
This project is hosted by the Center for Theoretical Physics (CFT) of Polish Academy of Sciences. CFT brings together researchers from various fields related to theoretical physics, astrophysics and natural sciences: classical and quantum field theory, quantum optics, basics of quantum mechanics and quantum information theory, physics of new states of matter, cosmology and astronomy.
