Solvable relaxation in discrete unitary systems: Ruelle-Pollicott resonances and CMV matrices
Urban Duh, Friedrich Hübner, Marko Žnidarič
Leading eigenvalues of the truncated propagator, known as Ruelle-Pollicott (RP) resonances, are an elegant way of addressing the dynamics of unitary many-body systems. We study uni…

Ruelle-Pollicott resonances of diffusive U(1)-invariant qubit circuits
Urban Duh, Marko Žnidarič
We study Ruelle-Pollicott resonances of translationally invariant magnetization-conserving qubit circuits via the spectrum of the quasi-momentum-resolved truncated propagator of ex…
