The Centre for Ultrafast Imaging (CUI) operates the DFG Cluster of Excellence “Advanced Imaging of Matter”, consisting of partners from UHH, DESY, the Max Planck Institute for Structural Dynamics, and the European XFEL. Together, we aim to understand and manipulate the processes that arise from arrangements of atoms and molecules in different forms of matter. We image quantum processes in...
Quantum technology holds great promise for information processing, communication and sensing. However, quantum states incredibly are fragile, quickly losing their advantages properties under most circumstances. To get the technology out of the lab, into the real world, extraordinary materials are required, which exhibit robust quantum states - a challenging task, but not impossible: Join me on...
Spontaneous symmetry breaking in the Mexican-Hat potential leads to massless phase modes as low-energy excitations. In superconductors, however, coupling between the charged condensate and the gauge field shifts the phase mode to higher energies,[1] leaving the Higgs mode as the dominant low-energy excitation. The Meissner effect reflects a macroscopic quantum condensate where photons gain...
The WAVE initiative at Hamburg’s Science City Bahrenfeld brings together physicists, geophysicists, and engineers from the University of Hamburg, Helmut-Schmidt University, DESY and EuXFEL.
We have developed a dense seismic sensor network by using fiber-optic sensing technology to tap into telecommunication fiber. With this, we record both anthropogenic and natural vibrations and study their...
The CRR cleanroom at the bahrenfeld Campus, managed jointly by UHH, DESY and MPI, is a versatile platform, where users can access a variety of rooms for patterning at the micro and nanoscale. These include laser, optical and electron-beam lithography, thin film deposition, dry and wet etching,etc. The platform is used by groups in different research fields, such as the development of new...
In this talk we will highlight some recent research highlights in
mathematical optimization with applications to material science.
Topics range from free material optimization for the design of
optimal macroscopic material properties to shape optimization
approaches for the microscale design of meta materials with desired macroscopic properties.
Biological materials achieve an exquisite diversity and functionality through just a small number of abundant chemical elements. While engineering materials primarily use specific, often unsustainable, chemical compositions to realize their functions, nature achieves unparalleled functionality through optimized architectures that span multiple length scales. Water, with its ubiquity and unique...
Plants are hierarchically organized porous material systems with multiple functions that are intricately driven by water transport and distribution. The interplay between material composition, structural organization, and emergent function in plants offers powerful design principles for the development of next-generation technical material systems. By translating these biological strategies,...
Modern chemical production still depends heavily on fossil resources such as oil, gas, and coal. These raw materials have enabled the development of fuels, plastics, and countless everyday products. Yet, if we want to build a more sustainable future, we must replace fossil feedstocks with renewable alternatives such as biomass or carbon dioxide. This shift is not straightforward: renewable raw...
The f-elements (lanthanoids and actinoids) possess a variety of properties which make them invaluable or promising for a variety of applications, such as in electronics, optics or as catalysts. However, a thorough understanding on how to tune these properties on the molecular level is often lacking. This talk will highlight our approach towards a more rational design of new f-element compounds.
Hybrid metal–semiconductor nanostructures offer promising properties by combining fast electron transfer with efficient charge separation. While metal growth on nanorods is well-studied, selective growth on quasi-2D CdSe nanoplatelets (NPLs) remains underexplored. CdSe NPLs, only a few monolayers thick, exhibit exceptional optical features such as high quantum yields and narrow emission bands....
