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)=∑i(−1)idim HomD(A,B[i])
). Thank you.
