Revised Project List
(Please give your input here, and add a 2 or 3 line description of the content of each project)
- Cluster methods for spin systems (TP, AH, SW)
- Additionally interested: AL
- 2 PhD (Gö) = 1.5
- Outline: Step 1: Set up a cluster dynamical mean-field framework for (frustrated) spin systems. Step 2: Test solution with an ED impurity solver (frustrated systems are expected to yield a sign problem). Step 3: Work on QMC impurity solver(s). Go back to step 1 whenever necessary.

- Outline.
- Further development of continuous time QMC for clusters with bosonic and fermionic baths.
- Problem: very long autocorrelation times calls for better updating schemes.
- Applications. Electron-phonon and electron-electron correlations. eg: TTF-TCNQ. 2D CDW.
- EDMFT.
- Philipp, Matthias and Thomas please let me know if you have further suggestions.

- Low, but finite temperatures
- Comments:
- formerly 5. DDMRG++ (EJ & RN)
- Goettingen definitely is interested here, too (not necessarily requesting resources, though)
