Physics in Chemnitz over the years
The Institute of Physics is celebrating its 70th anniversary this year. Reason enough to take a glance at the Institute's past and take a closer look at the history of physics at Chemnitz University of Technology: The Institute of Physics was established at the Hochschule für Maschienenbau(HfM) in 1954, just one year after the HfM was founded in 1953. As a result of the 3rd university reform in 1963, the Institute became the Physics/Electronic Components Section (PEB). From the fall of 1963, it trained physicists at the TH Karl-Marx-Stadt. In 1974/1975, the Weinhold Building was completed, which was to become the home of the Institutes of Physics and Electrical Engineering for the next 33 years. In 1992/93, a total of 10 new professorships were added to the existing 7 physics professorships as part of the relaunch of the universities in Saxony. In 2008, the time had come and the physics department moved into its new institute building. This year also marked the start of the staged Bachelor's and Master's degree in physics. In 2010, the Bachelor's/Master's degree course in Sensorik und kognitive Psychologie was launched, which remains particularly popular to this day and is the course with the largest number of students at the Institute of Physics.

The cochlea forms a key element of the human auditory system in the temporal bone. Damage to the cochlea continues to produce significant impairment for sensory reception of environmental stimuli. To improve this impairment, the optical cochlear implant forms a new research approach. A prerequisite for this method is to understand how light propagation, as well as scattering, reflection and absorption, takes place within the cochlea. We offer a method to study the light distribution in the human cochlea through phantom materials which have the objective to mimic the optical behaviour of bone and Monte‐Carlo simulations. The calculation of an angular distribution after scattering requires a phase function. Often approximate functions like Henyey‐Greenstein, two‐term Henyey‐Greenstein or Legendre polynomial decompositions are used as phase function. An alternative is to exactly calculate a Mie distribution for each scattering event. This method provides a better fit to the data measured in this work.

Publication: Simultaneous occurrence and compensating effects of multi-type disorder in two-dimensional photonic structures
Authors: D. Röhlig, E. Kuhn, A. Thränhardt, T. Blaudeck
Journal: Nano Select 4, 368 (2023)
Finite-difference time-domain (FDTD) simulations of the transmission spectra of planar small-footprint photonic components with up to four types of morphological disorder as a materials parameter are performed with the aim to identify the individual contributions of the type of disorder to the spectral features. Our work shows that several types of disorder as well as the mixing two types of disorder can be used for an intentional adaptation of the spectral transmission characteristics and may be considered in the design of small-footprint photonic components such as scatterers, diffusers, and waveguides.

How did science work in the Middle Ages? Did Newton really discover gravity when an apple fell on his head? How did the interpretations of quantum mechanics develop and become accepted? Hans-Reinhard Berger will once again read the lecture „Geschichte der Physik“ (in german) on these and other questions on the development of physical theories in the upcoming summer semester 2023.- Time: every friday, 13:45 - 15:15

Journal: GIT Labor-Fachzeitschrift, 11-12, 29 (2022)
Optical spectroscopy methods in the ultraviolet, visible and near infrared spectral ranges have proven to be powerful methods for structural analysis. This article describes how small technical advancements of a microreflectance spectroscopy setup in terms of focusing in different geometric planes and orientations of the sample can help to shed light, in the proverbial sense, on the internal morphology and light scattering properties of a new class of three-dimensional, liquid-processed, colloidal, nanostructured photonic objects.
TUC explains Nobel Prizes
This year, the Nobel Prize in Physics was awarded for experiments with entangled photons and pioneering work in the field of quantum information. In the field of chemistry, the development of click chemistry and its application in living cells was awarded. What are these topics about and why are they so important for the natural sciences? These and other questions will be answered at the event.- Time: 13th december 2022, 17:00 - 18:15

Fabian Teichert receives the 2022 Teaching Award for Young Scientists
The teaching award for young academics who teach illustrates that Chemnitz University of Technology recognises research and teaching as equally important areas, even in the qualification phase, and appreciates the commitment of young academics in teaching. The teaching prize is also intended as a career incentive to commit to qualitative university teaching and is awarded for the successful combination of research and teaching.
Hans-Reinhard Berger is one of the 175 inspiring people of the DPG
On 175 days in the anniversary year of the DPG, interesting physicists will be presented who have an inspiring effect on other people or even on society as a whole through their field of activity, their commitment or their thoughts.„Physik ist wie ein Bachsches Oratorium, bei dem man von unerwarteten, letztlich aber den Inhalt unterstützenden Harmonien überrascht wird.“
