[Isac-journal-club] Paper for next week

[Ragnar Stroberg]

Hi all,

Here is the paper we will be discussing next Wedensday (attached, also
including supplemental material in case you get bored this weekend).

http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.117.132501

with an accompanying Physics Viewpoint (this might be a good place to
start):

http://physics.aps.org/articles/v9/106

Questions to guide your reading:

1) What is the difference between a local and non-local interaction?
2) What is the many-body method used in this work?
3) What is a scattering length?
4) What is a quantum phase transition?
5) What is the meaning of the parameter lambda used in this paper?
6) At which order of chiral effective field theory to they work?

Questions for discussion:

1) Are the results credible?
2) What should we take away from the claim that "nature is near a quantum
phase transition"?
3) How can this study help us understand clustering in nuclei?
4) Why are people so excited about Efimov physics?
5) In the end, is this useful or just cute?


Happy reading,

-Ragnar
