AI Thread Summary
Current advancements in creating ultra-cold environments for atoms, particularly in relation to Bose-Einstein condensates (BEC), are a topic of interest, but recent comprehensive reviews are scarce. Most available literature dates back to the 1990s, with newer articles focusing on narrower aspects of the research. The discussion highlights a need for updated resources that summarize the latest findings in this field. Participants suggest checking references from existing articles, though many are outdated. Continued exploration and sharing of recent studies are encouraged for better understanding of current capabilities in ultra-cold atom research.

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.

Some, not all. But most date back a bit, and the more recent ones are quite narrow in their content. Didn't see any recent review article or the likes.
 
Been around 40 years since I took basic physics in college and while I remember doing some examples of insulation values / energy conduction, I doubt I could to the math now even if I could find the formulas. I have some some corrugated plastic sheet (think of the plastic signs you see on the side of the road) that is used in bee hives. Also have some used in a green house though a bit different in dimensions than this example but the general approach should still apply. Typically, both...
Problem: You’re an Uber driver with a Tesla Model 3. Today’s low: 30F, high: 65F. You want to reach a USD$ profit target in the least number of hours, but your choices could have added cost. Do you preheat the battery only when you are headed to the charging station (to increase the charging rate by warming the battery — however the battery might not be “warm enough” when your reach the charger and thus slower charging rates), or do you always “navigate to the charger” the entire day (which...
Thread 'Is Callen right in claiming dQ=TdS for all quasi-static processes?'
Hello! I am currently reading the second edition of Callen's Thermodynamics and an Introduction to Thermostatistics, and I have a question regarding Callen's definition of quasi-static. On page 96, Callen says: Another way of characterizing Callen's definition is that a process is quasi-static if it traces out a continuous curve in the system's configuration space. So far it's all well and good. A little later, Callen claims that the identification of $$TdS$$ as the heat transfer is only...
