Quantum Material Control

Molecular quantum switches get help from the surfaces they are adsorbed on. In porphycene molecules, heavy surface atoms like copper participate in the intramolecular hydrogen tunneling reaction and can cause an increase in the tunneling rate by up to two orders of magnitude at a temperature of around 80 K. more

Research team develops method to detect the dynamics of light on ultrasmall scales using a highly sensitive tracer molecule. The magnesium phthalocyanine molecule acts as a trigger switch which detects changes in the local electro-magnetic fields. more

Symmetrically coupled light and matter can produce a new combined state of light and electrons – a state which could be utilized in the design of new materials.  more

Researchers show that short-lived topological states can be tracked with equally short light flashes spiraling like a corkscrew, using signal difference between left- and right-handed light. more
