Title: Roton Metamaterials
Abstract: Based on the pioneering work of Lev Landau and Richard Feynman, rotons were observed in inelastic neutron scattering experiments on superfluid helium in 1961. For the roton dispersion relation, energy and momentum of the acoustical wave are proportional to each other for small momenta. For larger momenta, a (roton) minimum of energy versus momentum occurs. Rotons have also been investigated in other correlated quantum systems at low temperatures, such as quasi two-dimensional thin films of 3He, quantum Hall effect stripes in semiconductors, and Bose-Einstein condensates of atoms. In this talk, we present the physics and design of metamaterials showing roton dispersion relations under ambient conditions.
Biography: After completing his Diplom and PhD in physics at Johann Wolfgang Goethe-Universität Frankfurt (Germany) in 1986 and 1987, respectively, he spent two years as a postdoc at AT&T Bell Laboratories in Holmdel (U.S.A.). From 1990-1995 he was professor (C3) at Universität Dortmund (Germany), since 1995 he is professor (C4, later W3) at Institute of Applied Physics of Karlsruhe Institute of Technology (KIT). Since 2001 he has a joint appointment as department head at Institute of Nanotechnology (INT) of KIT, since 2016 he is one of three directors at INT. From 2001-2014 he was the coordinator of the DFG- Center for Functional Nanostructures (CFN) at KIT. Since 2018 he is spokesperson of the Cluster of Excellence 3D Matter Made to Order. His research interests comprise ultrafast optics, (extreme) nonlinear optics, optical laser lithography, photonic crystals, optical, mechanical, electronic, and thermodynamic metamaterials, as well as transformation physics. This research has led to various awards and honors, among which are the Alfried Krupp von Bohlen und Halbach Research Award 1993, the Baden- Württemberg Teaching Award 1998, the DFG Gottfried Wilhelm Leibniz Award 2000, the European Union René Descartes Prize 2005, the Baden-Württemberg Research Award 2005, the Carl Zeiss Research Award 2006, the Hector Research Award 2008, the SPIE Prism Award 2014 for the start-up company Nanoscribe GmbH, the Stifterverband Science Award – Erwin-Schrödinger Prize 2016, and the Technology Transfer Prize of the German Physical Society (DPG) 2018. In 2014, 2015, 2016, 2017, 2018, and 2020 Clarivate Analytics listed him as “Highly Cited Researcher” (top 1%). He is Member of Leopoldina, the German Academy of Sciences (since 2006), Member of acatech, the National Academy of Science and Engineering (since 2019), Member of the Hector Fellow Academy (since 2013, presently also President), Fellow of the Max Plack School of Photonics (since 2019), Fellow of the Optical Society of America (since 2008), and Honorary Professor at Huazhong University of Science & Technology, Wuhan, China (since 2014).

MIMS22: 2022 International Workshop on Multiscale Innovative Materials and Structures
We are delighted to announce the “2022 International Workshop on Multiscale Innovative Materials and Structures ” (MIMS22) ” to be held from September 29th through October 1st, 2022 in Cetara (Amalfi Coast) – Salerno, Italy. This will be the fourth edition of a fortunate series of international workshops held on the Amalfi Coast every three years, since 2013 (www.multiscale.unisa.it).
You are cordially invited to participate in this workshop. Abstracts related, but not limited, to the following areas are welcome:
– Multiscale mechanics
– Architectured materials and sustainable composites
– Mechanical and acoustic metamaterials
– Smart materials and structures
– Granular materials and systems
– Microstructure engineering
March 1st, 2021: Abstract submission opens
December 31st, 2021: Abstracts due
January 31st, 2022: Abstracts reviewed
February 1st, 2022: Early Registration opens
July 30th, 2022: Registration closes
Please visit the MIMS22 website for updates on this event, (www.multiscale.unisa.it) and contact us for any inquiries (email@example.com). The flyer of the event is attached for your convenience.
A special issue of Mechanics Research Communications edited by the conference chairs will collect original, peer-reviewed contributions presented at the Workshop. Papers in this issue are aimed at bringing together researchers working at the forefront of applied mechanics, material science and engineering, and physics to further our understanding of mechanics of materials at different scales, and its application to the design, modeling, manufacturing and experimentation of innovative multiscale materials and structures. The deadline of submission of full papers will be communicated on the conference website.
The Workshop will be held at the Cetus Hotel (www.hotelcetus.com) located in a scenic venue of the amazing Amalfi Coast. The hotel is equipped with 37 rooms, all with sea view, and may host up to 91 participants. Alternative accommodations are available at nearby hotels (www.multiscale.unisa.it).
We hope to see you in Cetara in October 2022!
