    "abstract": "We propose a cooling scheme based on depolarisation of a polarised cloud of\ntrapped atoms. Similar to adiabatic demagnetisation, we suggest to use the\ncoupling between the internal spin reservoir of the cloud and the external\nkinetic reservoir via dipolar relaxation to reduce the temperature of the\ncloud. By optical pumping one can cool the spin reservoir and force the cooling\nprocess. In case of a trapped gas of dipolar chromium atoms, we show that this\ncooling technique can be performed continuously and used to approach the\ncritical phase space density for BEC",
