- Follow Roman Bause, Postdoc (former PhD) at the Max Planck Institute of Quantum Optics, to his quantum gas lab, where he and his group cool small molecules down to the lowest temperatures ever reached, only a few billionths of a degree above absolute zero. The group creates degenerate dipolar quantum gases of NaK ground state molecules starting from an ultracold mixture of sodium and potassium atoms. Their strong and anisotropic long-ranged interaction allows to investigate the rich physics of dipolar many-body systems in a strongly-interacting regime. Currently the group are following particularly two research topics:
I. One is understanding and controlling collisions of molecules to remove entropy from the Fermionic molecular gas. We already have the coldest dipolar ground state molecules and are still trying to make the system colder.
II. The other is to simulate novel spin models and extended Hubbard model beyond nearest-neighbor interactions by trapping the molecules in an optical lattice.
The big goal: use the ultracold polar molecules to simulate so far unsolvable problems in the understanding of materials (like superconductivity) and in other systems where quantum effects play a larger role.
Very good presentation. Never knew before how to cool with lasers. Thx! Keep up the good work!😊
good luck guys
Looks beautiful
Excellent presentation! Kudos to Roman.
Really insightful video!
What a great video
wow
Wow to the tenth nanokelvin
What are some of the experiments you’re most excited about?
@7:47 is just beautiful
Just stunning experimental technique. Does zero degrees Kelvin exist in the cosmos?
That against uncertainty isn't it
Looks lovely ❣
'Former' Ph.D.? Huh. Was it taken away as a Post-Doc?😅
postgraduate cashcow based on
theoretical maths(guessing and making up values for invented symbols representing the results of theoretical algebra..)but having a,word salad backed by coding written to produce the result that guarantees funding (talking in circles about assumptions that reinforce the algebra you invented to get funding)...trillions...but really just like the japanese that youll jag some process that produces nihonium,but misdirecting about it.
Hey dude, can I have some of that stuff you're smoking? It sure must be strong!
@@MoraFermi misdirection response,has no clue.
