Correlations and commuting transfer matrices in integrable unitary circuits
Correlations and commuting transfer matrices in integrable unitary circuits
We consider a unitary circuit where the underlying gates are chosen to be \check{R} <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mover><mml:mi>R</mml:mi><mml:mo accent="true">̌</mml:mo></mml:mover></mml:math> -matrices satisfying the Yang-Baxter equation and correlation functions can be expressed through a transfer matrix formalism. These transfer matrices are no longer Hermitian and differ from the ones guaranteeing local conservation laws, …
