I was listening to the RadioLab podcast this morning (if you don't know RadioLab, you should (http://blogs.wnyc.org/radiolab/), and they had They Might Be Giants on. They Might Be Giants just released their 14th album, a kids album called "Here Comes Science". It's great! Anyway. During this podcast, they challenged They Might Be Giants to make a song up on the spot using the phrase, "Quantum decoupling transition in a one-dimensional Feshbach-resonant superfluid". Being They Might Be Giants, they did a great job.
I decided to pick up where they left off though, and use today's song a day song to write the full song. The lyrics come from an abstract that Sheey DE and Radzihovsky L. wrote on the subject in Sep. of 2005. I have NO idea what any of it means. I changed only one word...leaving out "Luttinger", because I couldn't figure out how to say it. Yay!
We study a one-dimensional gas of fermionic atoms interacting via an s-wave molecular Feshbach resonance. At low energies the system is characterized by two Josephson-coupled Luttinger liquids, corresponding to paired atomic and molecular superfluids. We show that, in contrast to higher dimensions, the system exhibits a quantum phase transition from a phase in which the two superfluids are locked together to one in which, at low energies, quantum fluctuations suppress the Feshbach resonance (Josephson) coupling, effectively decoupling the molecular and atomic superfluids. Experimental signatures of this quantum transition include the appearance of an out-of-phase gapless mode (in addition to the standard gapless in-phase mode) in the spectrum of the decoupled superfluid phase and a discontinuous change in the molecular momentum distribution function.

Quantum decoupling transition in a one demensional Feshbach-Resonant?!?!?!?!?!?!!
?!?!?!?!?!?!?!? plz someone help me out here. love the song but would sove to know what he means? -
Radzihovsky one of my current professors. win.
