Brief introduction to single band BCS theory (ala Gorkov/Sigrist/Ueda/Rice/Volovik)
Momentum space topological nodal classification - discrepancies with single-band theory (maybe review real space 10-fold classification as well).
New superconductivity physics from additional degrees of freedom (Bogoliubov Fermi surfaces, fully gapped SC when nodes expected, breakdown of Blount's theorem, other examples).
Band descriptions including additional degrees of freedom (band representations with orbital, sublattice, spin and including non-symmorphic groups).
Representative tight-binding Hamiltonians of the above and applications to magnetism and superconductivity (likely chosen from my recent research).
Andrey Chubukov
FTPI, University of Minnesota
Lecture 1. BCS (briefly), superconductivity from nominally repulsive Coulomb interaction, Kohn-Luttinger superconductivity in 3D and 2D. Applications to cuprates (d-wave), Fe-based (s+-) , doped graphene (d+id) and twisted WSe2.
Lecture 2. a) Renormalization group treatment of SC [using Fe-based as an example]. b) Pairing by collective fluctuations (spin and charge) as an extention of Kohn-Luttinger, with FM and AFM spin fluctuations as two examples. c) Discussion on how to obtain an effective pairing interaction mediated by a coll. mode
Lecture 3. Interplay between the self-energy and pairing vertex. Eliashberg theory for both electron-phonon and collective mode cases and the limits of its applicability. Role of thermal fluctuations for spin-singlet and spin-triplet pairing (with application to electron-doped cuprates).
Lecture 4. Pairing at a QCP. a) Non-BCS pairing scenario. b) Threshold on the interaction and multiple solutions. c) Application to pairing at a van Hove point [BCS-looking formula for Tc, but non-BCS pairing mechanism].

University of Massachusetts, Amherst

LOCATION
The School will take place in Kenneth H. Keller Hall 3-180 (ground floor), 200 Union Street SE, Minneapolis 55455.
The Pizza party will take place in the atrium of John T. Tate Hall, 116 Church Street, SE, Minneapolis 55455
GROUND TRANSPORTATION
Once you land at the Minneapolis/St. Paul International Airport (MSP), you have several options you can take to get to the University of Minnesota (UMN). There is Light Rail, shuttle, Lyft/Uber and taxi services from the airport. Car rental is not encouraged because it is unnecessary and parking is expensive.
If you are arriving/departing late at night we recommend taking a Lyft/Uber or taxi.
Light Rail: take the blue line from either Terminal 1 or 2 to the US Bank Stadium station. There you should make a transfer to the green line heading east to campus. Your final stop on the green line will be the East Bank station
LODGING
Out of town participants will stay in dorm rooms at Pioneer Hall and Centennial Hall. Participants will receive individual messages regarding their reservations.
PARKING
If you are driving to the UMN campus the most economical option for parking is the Maroon lot at $6 per day. You will get a ticket when you enter and pay when you exit. You can leave your car here for the duration of the school and overnights are not a problem.
HOMEWORK AND PRESENTATIONS OF HOMEWORK SOLUTIONS
The student body will be split into three subgroups. Each group will receive a problem from one of the three lecturers on Monday. Groups have until Friday to solve the problem working within the subgroup. On Friday, a group representative will present the solution and defend it to the full audience (30 min per subgroup).
POSTER SESSIONS
Poster sessions have been added to the program. There will be a poster session on Tuesday, July 29th and Thursday, July 31st. We will split students into two groups. Group I will have presentations on Monday and a poster session on Tuesday. Group II will have presentations on Wednesday and a poster session on Thursday. We will send details closer to the start of the school. Posters will be attached to foam core boards and placed on easels. Recommended poster size is 4 x 4 feet but can be larger or smaller.
SHORT PRESENTATIONS BEFORE POSTERS
Each person will have 2 minutes to either advertise their poster or, if you prefer, tell us about something new. This should surprise others and force them to think about what you have said.
POSTER PRINTING
Poster printing may be done through Coffman Memorial Union Print Center. They require a PDF in the requested size you would like the poster printed (one dimension needs to be 44" or under.) The cost is $8 per square foot. For example a 36x48 inch poster is $96. Email cmucc@umn.edu - you may pay with cash or card.
