New microscopy technique for quantum simulation

Method can be used to explore entirely new regimes

26-Nov-2021

Researchers from the Institute of Laser Physics at Universität Hamburg have developed a new technique for quantum gas microscopy that now allows imaging of three-dimensional quantum systems. In the journal Nature, they report on the new method, which can be used to explore entirely new ...

Using corkscrew lasers to separate mirror molecules

Innovative approach could deepen insight into the mysterious handedness of life

13-Dec-2019

Many of the molecular building blocks of life have two versions that are mirror images of one another, known as enantiomers. Although seemingly identical, the two enantiomers can have completely different chemical behaviour – a fact that has major implications in our day-to-day lives. For ...

Spontaneous occurrence of skyrmions in atomically thin cobalt films observed

27-Aug-2019

Since their experimental discovery, magnetic skyrmions - tiny magnetic knots - have moved into the focus of research. Scientists from Hamburg and Kiel have now been able to show that individual magnetic skyrmions with a diameter of only a few nanometres can be stabilised in magnetic metal films ...

Laser trick produces high-energy terahertz pulses

Milestone for compact particle accelerators

17-Jun-2019

A team of scientists from DESY and the University of Hamburg has achieved an important milestone in the quest for a new type of compact particle accelerator. Using ultra-powerful pulses of laser light, they were able to produce particularly high-energy flashes of radiation in the terahertz range ...

Flexible circuits for 3D printing

New process for flexible and transparent electronics

29-Apr-2019

A research cooperation between the University of Hamburg and DESY has developed a process suitable for 3D printing that can be used to produce transparent and mechanically flexible electronic circuits. The electronics consists of a mesh of silver nanowires that can be printed in suspension and ...

Disrupting crystalline order to restore superfluidity

16-Oct-2018

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, ...

Magnetic bits by electric fields

Making use of local electric fields for writing and deleting individual nanoscale magnetic skyrmions

08-Nov-2016

Physicists of the University of Hamburg in Germany have demonstrated for the first time the controlled writing and deleting of individual nanoscale magnetic knots – so called skyrmions – by applying local electric fields to an ultrathin film of iron as data storage medium. These tiny knots in the ...

Handshake of atoms: lefties or righties?

25-Feb-2016

A team of researchers from the Department of Physics at Hamburg University, together with col-leagues from the Radboud university in Nijmegen, the FZ Jülich and the MPI of Solid State Research in Stuttgart, explored the atomistic origin of magnetization handedness in a structure containing as few ...

Stability of magnetic bits defined by skyrmions

16-Oct-2015

One of the cogent necessities in the contemporary world is the storage of a vast amount of digital data. Currently, there are different methods available for that purpose including the use of differently magnetized ferromagnetic cells. All atomic magnets are aligned parallel within these cells ...
