Abstract
We have solved the negative-sign problem in a general frustrated double-spin-chain system, namely the J0-J1-J2-J3 model. This is made possible by changing the representation basis from the conventional sz basis to a dimer basis that has the spin-reversal symmetry. The necessary condition for the problem to disappear in this new basis is J0+J1≤J3. Frustration is the origin only in the conventional sz basis. We demonstrate the efficiency of this new basis at the transition point between the gapless spin-fluid phase and the gapped dimer phase.
