Abstract: We investigate sub-Doppler laser cooling of bosonic potassium isotopes, whose small hyperfine splitting has so far prevented cooling below the Doppler temperature. We find instead that the c...

The laser cooling and trapping of ultracold neutral dysprosium has been recently demonstrated
using the broad, open 421-nm cycling transition. Narrow-line magneto-optical trapping of Dy on
longer wa...

We present a laser cooling scheme for trapped ions and atoms using a combination of laser
couplings and a magnetic gradient eld. In a Schrie er-Wol transformed picture, this setup cancels the carri...

We propose and solve a simple but very general quantum model of an SU(2)spin interacting with a large external system with N states. The coupling is described by a random hamiltonian in a new general ...

In this paper, we study the laser cooling mechanisms with a new quantum theory approach by applying a new Schrodinger equation, which can describe a particle in conservative and non-conservative force...
April 5, 2007,Using a laser-cooling technique that could one day allow scientists to observe quantum behavior in large objects, MIT researchers have cooled a coin-sized object to within one degree of ...
