Striped high-Tc superconductors such as La⅞Ba⅛CuO4 show a fascinating competition between spin and charge order on one handside and superconductivity on the other handside. A theory for these systems therefore has to capture both the spin correlations in an antiferromagnet and the pair-correlation of a superconductor. For this purpose we developed an effective mean-field model by merging the theory of electron pairing with finite center-of-mass momentum with the antiferromagnetism known to coexist with d-wave superconductivity in systems with disorder. I will show that our model reproduces the key properties observed in experiments such as the formation of the antiferromagntic stripe pattern at ⅞ band filling or the quasi one-dimensional Fermi-surface observed by ARPES measurements. |
