Demonstration of atomic frequency comb memory for light with spin-wave storage (2009)
Afzelius, Mikael, Usmani, Imam, Amari, Atia, Lauritzen, Björn, Walther, Andreas, Simon, Christoph, ...
We present a light-storage experiment where the light is mapped onto an inhomogeneously broadened optical transition in a praseodymium-doped crystal, which is shaped into an atomic frequency comb....
Experimental superradiance and slow light effects for quantum memories (2009)
Walther, Andreas, Amari, Atia, Kröll, Stefan, Kalachev, Alexey
The effects of high optical depth phenomena, such as superradiance, are investigated in potential quantum memory materials. The results may have relevance for several schemes, including CRIB, AFC and...
Plamper, Felix A., Walther, Andreas, Mueller, Axel H. E., Ballauff, Matthias
We analyze the structure of star-shaped polyelectrolytes in the presence of di- and trivalent counterions, and we use the gained knowledge to manipulate the polyelectrolyte's conformation by light....
