From physical fundamental research to key technology in the 21th century
CRC TRR142 "Tailored Nonlinear Photonics: From Fundamental Concepts to Functional Structures" introduces himself and illustrates his reasearch in simple terms.
Sep 2019 - Dr. Xuekai Ma visited with Prof. Yaroslav Kartashov the Institute of Photonic Sciences (ICFO) in Barcelona, Spain.
Collaboration on a novel concept to achieve parity-time (PT) symmetry in exciton-polaritons in a semiconductor micro resonator
Exchange with our project partner in China - Prof. Zentgraf (Project leader in the TRR142) visits the Beijing Institute of Technology in Beijing (China)
Using tailored and ringshaped laser profiles, TRR researchers demonstrate the existence of a vortex multistability in a planar optically driven semiconductor micro resonator.
Publication in Science Advances about two photons which meet on a single chip
Physicists from the University of Paderborn have for the first time succeeded in realizing the key building blocks of quantum photonics, the full Hong-Ou-Mandel experiment showing the bunching of two single photons on a single chip. This is an important step for establishing the new quantum technology. It is needed e.g. for synchronization of quantum communications,…
Clarivate Analytics, known for their internet platform Web-of-Science, announces the Highly Cited Researchers List 2018, a list of elite scientists and social scientists identified through analysis of highly cited papers (those ranking in the top 1% by citations for field and year). This year, for the first time, Clarivate Analytics has introduced a new Cross-Field category to identify researchers with substantial influence across several fields…
Congratulations to graduates in the TRR142 - Felicitats Walter successfully finished her PhD - Daniel Frese finshed his master thesis and joined the TRr as Phd
A major breakthrough in the measurement and understanding of the electronic structure changes during chemical reactions has been achieved by a team of physicists led by Martin Wolf (Fritz-Haber-Institut Berlin) and Wolf Gero Schmidt (Universität Paderborn). The researchers were able to monitor for the first time the redistribution of electrons during a chemical reaction in real time. The corresponding driving forces and mechanisms could be…

TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen
Die 44. Praktikumsleitertagung PLT 2018 der AG Physikalische Praktika (AGPP) der Deutschen Physikalischen Gesellschaft (DPG) fand in diesem Jahr am Department Physik der Universität Paderborn statt. Die jährliche Tagung, die jeweils von einer anderen Universität ausgerichtet wird, dient dem Erfahrungsaustausch zu einer der zentralen Lehrveranstaltungen im Physikstudium: den Laborpraktika. In diesen Lehrveranstaltungen werden Studierende an die…
Scientists from the Universities of Konstanz and Paderborn have succeeded in realizing and proving the so-called Wannier-Stark localization for the first time in a high-purity bulk gallium arsenide crystal manufactured at ETH Zurich. Physicists have overcome hurdles that have long been considered insurmountable in the field of optoelectronics and photonics. With this breakthrough, they have made it into "Nature Communications". Project A02 and…
With the award of a Heisenberg Professorship from the Deutsche Forschungsgemeinschaft to Stefan Schumacher in 2015, the new Professorship “Theory of Functional Photonic Structures” was established in the Physics Department at Paderborn University. The Heisenberg Professorship now receives funding for a second funding period. With this continued support, the DFG recognizes the excellent research achievements during the first funding period and the…
