论文摘要
引入了一种允许访问边界驱动XXZ旋转链的幻象伯特境（PBS）家族的耗散方法。该方法包括将开放自旋链的末端耦合到合适的耗散磁性浴中，以迫使边缘旋转以满足PBS存在所需的特定边界条件。随着耗散幅度增长的密度基质的非手续成分的累积单调减少与热冷却响应的高能状态相似。与通用状态相比，PBS具有强烈的手性，非平凡的拓扑结构并具有高自旋电流。
A dissipative method that allows to access family of phantom Bethe-states (PBS) of boundary driven XXZ spin chains, is introduced. The method consists in coupling the ends of the open spin chain to suitable dissipative magnetic baths to force the edge spins to satisfy specific boundary conditions necessary for the PBS existence. Cumulative monotonous depopulation of the non-chiral components of the density matrix with growing dissipation amplitude is analogous to the depopulation of high-energy states in response to thermal cooling. Compared to generic states, PBS have strong chirality, nontrivial topology and carry high spin currents.
