Solvable Quantum Circuits from Spacetime Lattices
Michael A. Rampp, Suhail A. Rather, Pieter W. Claeys
In recent years dual-unitary circuits and their multi-unitary generalizations have emerged as exactly solvable yet chaotic models of quantum many-body dynamics. However, a systemat…

Free Cumulants and Full Eigenstate Thermalization from Boundary Scrambling
Felix Fritzsch, Gabriel O. Alves, Michael A. Rampp +1
Out-of-time-order correlation functions (OTOCs) and their higher-order generalizations present important probes of quantum information dynamics and scrambling. We introduce a solva…

Geometric constructions of generalized dual-unitary circuits from biunitarity
Michael A. Rampp, Suhail A. Rather, Pieter W. Claeys
We present a general framework for constructing solvable lattice models of chaotic many-body quantum dynamics with multiple unitary directions using biunitary connections. We show…
