Reverse Doppler effect in backward spin waves scattered on acoustic waves
, 2009 We report on the observation of reverse Doppler effect in backward spin waves reflected off of surface acoustic waves. The spin waves are excited in a yttrium iron garnet (YIG) film. Simultaneously, acoustic waves are also generated.

Sub-Doppler laser cooling of fermionic 40K atoms in three-dimensional gray optical molasses
, 2012 We demonstrate sub-Doppler cooling of 40K on the D_1 atomic transition. Using a gray molasses scheme, we efficiently cool a compressed cloud of 6.5x10^8 atoms from ~ 4\mK to 20uK in 8 ms.

Negative refraction with tunable absorption in an active dense gas of atoms
, 2012 Applications of negative index materials (NIM) presently are severely limited by absorption. Next to improvements of metamaterial designs, it has been suggested that dense gases of atoms could form a NIM with negligible losses.
