Hello PF. I thought this would be a good place to ask around for information pertaining to "where we are at" in controlled creation of ultra-cold environments for atoms; for example, how cold an environment can we actually make today, etc.? I am especially interested in the BEC phenomena. When I search for information I tend to find articles and the likes dating from the 90's. I'd like to see some newer results. Anyone know of any recent review article perhaps? Or maybe some personal input to this matter? Guidance much appreciated. Thanks in advance.
