我们研究了响应于电压开关从受限电子系统进入弱耦合电极的瞬时热流。我们表明，该排斥系统的库仑相互作用能的衰减表现出电子-电子吸引的签名，并由相互作用独立的速率。这只能从一般的对偶性来理解，它将量子系统的非幺正演化与具有反转能量的对偶模型的演化联系起来。从费米子宇称超选择假设推导出来，这种对偶性适用于一大类开放系统。
We study the transient heat current out of a confined electron system into a weakly coupled electrode in response to a voltage switch. We show that the decay of the Coulomb interaction energy for this repulsive system exhibits signatures of electron-electronattraction, and is governed by an interaction-independent rate. This can only be understood from a general duality that relates the nonunitary evolution of a quantum system to that of a dual model with inverted energies. Deriving from the fermion-parity superselection postulate, this duality applies to a large class of open systems.
