About the Collaborative Research Centre SFB 925

The SFB 925 addresses the dynamics of the many – one of the deepest and most challenging problems in modern physics: How does collective behaviour emerge from the interactions of multiple degrees of freedom, especially when the system is driven away from equilibrium? The spectacular advances in photon science with new sources of THz and X-ray radiation, in quantum gas physics and in many-body physics have put us in a unique position to tackle this problem comprehensively: We will go beyond imaging the quantum dynamics and reach out to steer many-body states with light to reach new emerging functionalities.

Scientists from DESY and the University of Hamburg succeeded in imaging snapshots of molecular orbitals of pentacene on metal surfaces during energy transfer. Their work has been recently published in the journal “Nature Communications”.

In his Nobel Lecture, Herbert Kroemer famously stated that “The interface is the device”. Scientists from DESY and Hamburg University unveiled fundamental electronic and structural dynamics of the hybrid organic/inorganic interface on an ultrafast timescale.

The image shows cold atoms (in yellow) in an optical resonator on their way to form a time crystal.

Researchers observe continuous time crystal

Researchers from the Institute of Laser Physics at Universität Hamburg have succeeded for the first time in realizing a time crystal that spontaneously breaks continuous time translation symmetry. They report their observation in a study published online by the journal Science on Thursday, 9 June, 2022.

Review on ultrafast control of quantum materials

A review involving a team of MPSD scientists, just published as a colloquium in the prestigious Reviews of Modern Physics, explores how light can fundamentally alter the properties of solids – and how these effects can be harnessed in future applications. The review on the latest developments in ultrafast materials science...
