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.

Researchers cast new light on magnons to verify topological phases in magnetic materials

Much recent research has focused on ‘topological’ materials – an intriguing type of solids which fall outside the standard classification into insulators and conductors. While their bulk is insulating, these phases are characterized by electrically conducting channels which appear at their edges. These resulting so-called...

Theoreticians discover why optical cavities curb the rate of chemical reactions

Chemical processes are all around us. From novel materials to more effective medicines or plastic products – chemical reactions play a key role in the design of the things we use every day. Scientists constantly search for better ways to control these reactions, for example to develop new materials. Now an international...

Terahertz light from superconducting stripes

Why do some materials carry electrical currents without any resistance only when cooled to near absolute zero while others do so at comparatively high temperatures? This key question continues to vex scientists studying the phenomenon of superconductivity. Now a team of researchers from Andrea Cavalleri’s group at the Max...
