Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-15 (2021)
Abstract A clinical implementation of cell-based bone regeneration in combination with scaffold materials requires the development of efficient, controlled and reproducible seeding procedures and a tailor-made bioreactor design. A perfusion system fo

Equal-time approach to real-time dynamics of quantum fields
Autor: Robert Ott, Torsten V. Zache, Jürgen Berges
Publikováno v: SciPost Physics, Vol 14, Iss 2, p 011 (2023)
We employ the equal-time formulation of quantum field theory to derive effective kinetic theories, first for a weakly coupled non-relativistic Bose gas, and then for a strongly correlated system of self-interacting $N$-component fields. Our results p

Robustness of gauge-invariant dynamics against defects in ultracold-atom gauge theories
Autor: Jad C. Halimeh, Robert Ott, Ian P. McCulloch, Bing Yang, Philipp Hauke
Publikováno v: Physical Review Research, Vol 2, Iss 3, p 033361 (2020)
Recent years have seen strong progress in quantum simulation of gauge-theory dynamics using ultracold-atom experiments. A principal challenge in these efforts is the certification of gauge invariance, which has recently been realized [Yang et al., ar

Nonequilibrium dynamics of fluctuations in an ultracold atomic mixture
Autor: Apoorva Hegde, Robert Ott, Andy Xia, Valentin Kasper, Jürgen Berges, Fred Jendrzejewski
Publikováno v: Physical Review A. 107
We investigate an ultra-cold mixture of Bose gases interacting via spin-changing collisions by studying the dynamics of spin fluctuations. The experimental implementation employs $^{23}$Na and $^{7}$Li atoms, which are prepared out of equilibrium acr

Imposante Dachwerke, Holzbrücken oder jahrhundertealte Glockenstühle beeindrucken nicht nur Baufachleute. Sie für die Zukunft zu erhalten, ist allerdings eine immense Herausforderung. Welches Fachwissen dazu nötig ist, zeigen die Beispiele in die

Femtosecond laser structuring of permeable and resorbable biomaterial
Autor: Swen Grossmann, Sabine Illner, Robert Ott, Grit Rhinow, Carsten Tautorat, Eric Bohne, Wolfram Schmidt, Niels Grabow, Klaus-Peter Schmitz, Stefan Siewert
Publikováno v: Current Directions in Biomedical Engineering, Vol 7, Iss 2, Pp 713-716 (2021)
Bioresorbable nanofiber nonwovens with their fascinating properties provide a wide range of potential biomedical applications. Modification of the material enables the adjustment of mechanical and biological characteristics depending on the desired a
