Dark matter has proven to be one of the most elusive mysteries of modern-day physics. The fact that we have, as of yet, not been able to detect its interaction with standard model particles points to two most straightforward explanations. Either its interactions are too rare or too feeble for the technological limitations of our detectors. Phonons are some of the softest excitations one can produce in condensed matter systems. However, their readout has proven to be a very challenging task. In this seminar, I will talk about the possibility of employing chiral phonons together with surface-based magnetometric readout as dark matter detectors of tomorrow with unprecedented energy sensitivity.
During the seminar, the basic principles of laboratory X-ray tomography will be presented, as well as various less traditional tomographic methods - such as dual-energy tomography, triggering and 4D tomography, etc. In the field of materials research, the possibilities of studying time-dependent processes - fracture mechanics, deformation of 3D structures, etc. will be shown. In terms of research of cultural heritage objects, various possibilities of processing tomographic data to make otherwise difficult-to-access information visible will be demonstrated - stratigraphy of Gothic panel paintings, reading of old prints, research of ancient lead artifacts.
