Query: Non Self-conjugate Strings, Singular Strings and Rigged Configurations
  in the Heisenberg Model   We observe a different type of complex solutions in the isotropic spin-1/2
Heisenberg chain starting from N=12, where the central rapidity of some of the
odd-length strings becomes complex making not all the strings self-conjugate
individually. We show that there are at most (N-2)/2 singular solutions for
M=4, M=5 down-spins and at most (N^2-6N+8)/8 singular solutions for M=6, M=7
down-spins in an even-length chain with N \geq 2M. Correspondence of the non
self-conjugate string solutions and the singular string solutions to the rigged
configurations has also been shown.
