# Examples of $1$-Calabi-Yau triangulated categories

Can you give me examples of $1$-Calabi-Yau triangulated categories $D$ different from the bounded derived category of coherent sheaves on an elliptic curve? I would like moreover the numerical Grothendieck group of $D$ to be of rank $2$ (by numerical Grothendieck group i mean the Grothendieck group modulo the pairing $$X(A,B)= \sum_i (-1)^i{\rm dim} \ {\rm Hom}_{D}(A,B[i])$$). Thank you.
