Department of Biophysical and Structural Research

The research of the BBiS department's staff is diverse and generally concerns three directions. The first direction relates to fundamental and applied research, including the study of broadly understood solid state physics, low-dimensional structures, acoustic radiation or the thermodynamic evolution of comets. The second direction is related to applications of physics in biology and medicine, including, among others: the possibility of using Raman and IR spectroscopy to search for markers providing answers in cancer treatment, medical imaging using the phenomenon of resonance or synchrotron radiation. The third line of research focuses on issues related to high-energy physics, and in particular concentrates on the theoretical analysis of selected processes occurring in high-energy hadronic collisions.

Thin-film semiconductor materials in photovoltaic applications. The use of computational and measurement physical methods in medicine.
Dr hab. Marcin Wesołowski, prof. UR	My research is related to the thermodynamic evolution of comets. In particular, they focus on the emission of cometary matter, e.g. as a result of a cometary outburst. A secondary interest is the widely understood popularization of astronomy.
Dr Anna Cisek	The subject of research focuses on high-energy physics and particle physics. Scientific research includes calculations of total and differential cross sections. The cross section as a function of many variables (e.g. energy, transverse momentum, rapidity, azimuth angle) for the production of vector mesons in photon-proton, proton-proton, photon-nucleus and nucleus-nucleus collisions. The calculation results are compared with experimental data from HERA, RHIC, Tevatron and LHC accelerators.
Dr Grzegorz Górski	The main topic of research is the transport properties of nanoscopic systems. Particular attention is paid to spin-dependent transport in a quantum dot system coupled with a metallic, ferromagnetic and superconducting electrodes. The transport properties of a quantum dot coupled with Majorana fermion are also considered.

Dr Mirosław Łabuz	In my research work I deal with a one-dimensional model of Heisenberg magnets for finite chains with a 1/2 spin on each node. By using several alternative methods, such as solutions to Bethe equations or rigged string configurations, I determine eigenstates of the problem and investigate the coherent and divergent points of various approaches describing the system under study, mainly for chains composed of several nodes. The key aspect necessary to understand the problem of short chains is also the use of the extension of the field of rational numbers by primitive roots of the N-th degree of unity, which is related to the appropriate structure of the Galois group. This topic is a part of the current research related to nanoscopic physics and quantum informatics.
